The following steps ensure that the environment is correctly configured:\n", + "\n", + "- **Assign Role:** First, use the `ACCOUNTADMIN` role, which has the highest level of access in Snowflake. This ensures that you have the necessary permissions to create and modify databases, schemas, and warehouses. If a different role has sufficient privileges, it can be used instead. \n", + "\n", + "- **Create Database and Schema:** A **database** is where all your data is stored, and a **schema** helps organize different tables and objects within the database. In this setup, we create a database named `fawazghali_db` and a schema called `fawazghali_schema`. The `OR REPLACE` option ensures that if they already exist, they are replaced with fresh instances. \n", + "\n", + "- **Select Database and Schema:** To make sure all subsequent SQL commands operate within the correct context, we explicitly set `fawazghali_db` as the active database and `fawazghali_schema` as the active schema. This avoids confusion and ensures that queries and table creations happen in the right location. \n", + "\n", + "- **Create and Use Warehouse:** A **warehouse** in Snowflake is a virtual compute engine that processes queries and computations. We create a warehouse named `fawazghali_wh`, replacing any existing instance.

This type of analysis is common in real estate search or determining the driving proximity to schools, businesses, or other facilities. For example, you can create a drive time polygon that represents how far you can drive in any direction from the center of a city in 20 minutes.\n\nYou can use service areas to build applications that:\n\n- Visualize and measure the accessibility of locations that provide some kind of service. For example, a three-minute drive-time polygon around a grocery store can determine which residents are able to reach the store within three minutes and are thus more likely to shop there.\n\n- By generating multiple service areas around one or more locations that can show how accessibility changes with an increase in travel time or travel distance. It can be used, for example, to determine how many hospitals are within 5, 10, and 15 minute drive times of schools.\n\n- When creating service areas based on travel times, the service can make use of traffic data, which can influence the area that can be reached during different times of the day.\n\n### What is ArcGIS Location Services?\n\nThe [ArcGIS Location Services](https://developers.arcgis.com/documentation/mapping-and-location-services/) are services hosted by Esri that provide geospatial functionality and data for building mapping applications. You can use the service APIs to display maps, access basemaps styles, visualize data, find places, geocode addresses, find optimized routes, enrich data, and perform other mapping operations. The services also support advanced routing operations such as fleet routing, calculating service areas, and solving location-allocation problems. To build applications you can use ArcGIS Maps SDKs, open source libraries, and scripting APIs.\n\n### What Youโ€™ll Learn \n\nIn this notebook you will be go over the steps for defining an UDF that invokes the Service Area endpoint, part of the ArcGIS Location Services.

The pack's adjustability makes it a viable option for a broad range of heights and torso lengths, expanding its potential user base.",0.84927857 diff --git a/Avalanche-Customer-Review-Analytics/customer_reviews_docx.zip b/Avalanche-Customer-Review-Analytics/customer_reviews_docx.zip new file mode 100644 index 0000000..ac73bc7 Binary files /dev/null and b/Avalanche-Customer-Review-Analytics/customer_reviews_docx.zip differ diff --git a/Avalanche-Customer-Review-Analytics/environment.yml b/Avalanche-Customer-Review-Analytics/environment.yml new file mode 100644 index 0000000..83a5d95 --- /dev/null +++ b/Avalanche-Customer-Review-Analytics/environment.yml @@ -0,0 +1,5 @@ +name: app_environment +channels: + - snowflake +dependencies: + - snowflake.core=* diff --git a/Avalanche-Customer-Review-Analytics/setup.sql b/Avalanche-Customer-Review-Analytics/setup.sql new file mode 100644 index 0000000..f79a2f4 --- /dev/null +++ b/Avalanche-Customer-Review-Analytics/setup.sql @@ -0,0 +1,61 @@ +-- STEP 1 +-- Create the avalanche database and schema +CREATE DATABASE IF NOT EXISTS avalanche_db; +CREATE SCHEMA IF NOT EXISTS avalanche_schema; + +-- STEP 2 +-- Option 1: Manual upload to Stage +-- Create the stage for storing our files +-- Uncomment code block below for this option: +-- +CREATE STAGE IF NOT EXISTS avalanche_db.avalanche_schema.customer_reviews + ENCRYPTION = (TYPE = 'SNOWFLAKE_SSE') + DIRECTORY = (ENABLE = true); +-- +-- Now go and upload files to the stage. +-- Once you've done that proceed to the next step + +-- Option 2: Push files to Stage from S3 +-- Uncomment lines below to use: +-- +-- Create the stage for storing our files +-- CREATE OR REPLACE STAGE customer_reviews + -- URL = 's3://sfquickstarts/misc/customer_reviews/' + -- DIRECTORY = (ENABLE = TRUE AUTO_REFRESH = TRUE); + + +-- STEP 3 +-- List the contents of the newly created stage +ls @avalanche_db.avalanche_schema.customer_reviews; + + +-- STEP 4 +-- USAGE +-- +-- Read single file +-- Uncomment lines below to use: +-- +-- SELECT +-- SNOWFLAKE.CORTEX.PARSE_DOCUMENT( +-- @avalanche_db.avalanche_schema.customer_reviews, +-- 'review-01.docx', +-- {'mode': 'layout'} +-- ) AS layout; + +-- Read multiple files into a table +-- Uncomment lines below to use: +-- +-- WITH files AS ( +-- SELECT +-- REPLACE(REGEXP_SUBSTR(file_url, '[^/]+$'), '%2e', '.') as filename +-- FROM DIRECTORY('@avalanche_db.avalanche_schema.customer_reviews') +-- WHERE filename LIKE '%.docx' +-- ) +-- SELECT +-- filename, +-- SNOWFLAKE.CORTEX.PARSE_DOCUMENT( +-- @avalanche_db.avalanche_schema.customer_reviews, +-- filename, +-- {'mode': 'layout'} +-- ):content AS layout +-- FROM files; diff --git a/Bioinformatics_Solubility_Dashboard/Bioinformatics_Solubility_Dashboard.ipynb b/Bioinformatics_Solubility_Dashboard/Bioinformatics_Solubility_Dashboard.ipynb new file mode 100644 index 0000000..4dc15ef --- /dev/null +++ b/Bioinformatics_Solubility_Dashboard/Bioinformatics_Solubility_Dashboard.ipynb @@ -0,0 +1,130 @@ +{ + "metadata": { + "kernelspec": { + "display_name": "Streamlit Notebook", + "name": "streamlit" + }, + "lastEditStatus": { + "notebookId": "7rpm6lxftnqo2r7bqwsp", + "authorId": "6841714608330", + "authorName": "CHANINN", + "authorEmail": "chanin.nantasenamat@snowflake.com", + "sessionId": "6c69bcea-e09a-4f87-a91d-99ff6aecc8bf", + "lastEditTime": 1741649071648 + } + }, + "nbformat_minor": 5, + "nbformat": 4, + "cells": [ + { + "cell_type": "markdown", + "id": "407331eb-29af-42a3-976c-43e3652cd685", + "metadata": { + "name": "md_title", + "collapsed": false + }, + "source": "# Build a Bioinformatics Solubility Dashboard in Snowflake\n\nIn this notebook, you'll build a **bioinformatics project** from scratch in Snowflake. \n\nBriefly, we're using the *Delaney* solubility data set.

Let me explain why it matters in simple terms.\n\n### Solubility\nSolubility is a molecule's ability to dissolve in a liquid, which literally means the ability to dissolve in human bloodstream and transport to its desired target in the human body. If it can dissolve, it can't work!\n\nPoorly soluble drugs might require higher doses or special formulations, leading to potential side effects or complicated treatment regimens. So we want drugs that are both effective and yet soluble so that fewer of it is required so as to minimize potential side effects.\n\n### Lipinski's Rule of 5\nDrug development often refer to a guidelines known as the Lipinski's Rule of 5 to predict whether a molecule will be soluble enough to make a good oral drug. This includes factors like:\n- Molecule's size\n- How water-loving or water-repelling it is\n- Number of hydrogen bond donors and acceptors\n\nUnderstanding and optimizing solubility helps pharmaceutical companies develop effective medicines that can be easily administered and work efficiently in the body." + }, + { + "cell_type": "markdown", + "id":

Task creates a new csv-file in the internal Stage\n* 2nd Task creates a broken csv-file into the internal stage\n* 3rd Task manually refreshes the Pipe to load the 2 new files from the source Stage into a target table\n* Pipe copy of the broken csv-file will fail -> logging file ingestion error to the event table\n* the Stream on the target table will catch the new data from the successful file ingestion\n* Stream triggers the root Task to run the graph\n* child Tasks call procedures and functions, which may fail at random -> logging Procedure and Task errors\n* parallel child Task will change the name of the source table of a Dynamic Table and then manually refresh the Dynamic Table -> logging Dynamic Table refresh error\n\n-> manually run the Trigger Task via the UI or SQL to

In practice, this means that they are often required to build models to: make forecasts, identify long running trends, and identify abnormalities within their data. However, Analysts are often impeded from creating the best models possible due to the depth of statistical and machine learning knowledge required to implement them in practice. Further, python or other programming frameworks may be unfamiliar to Analysts who write SQL, and the nuances of fine-tuning a model may require expert knowledge that may be out of reach. \n\nFor these use cases, Snowflake has developed a set of SQL based ML Functions, that implement machine learning models on the user's behalf. As of December 2023, three ML Functions are available for time-series based data:\n\n1. Forecasting: which enables users to forecast a metric based on past values. Common use-cases for forecasting including predicting future sales, demand for particular sku's of an item, or volume of traffic into a website over a period of time.\n2. Anomaly Detection: which flags anomalous values using both unsupervised and supervised learning methods. This may be useful in use-cases where you want to identify spikes in your cloud spend, identifying abnormal data points in logs, and more.\n3. Contribution Explorer: which enables users to perform root cause analysis to determine the most significant drivers to a particular metric of interest. \n\nFor further details on ML Functions, please refer to the [snowflake documentation](https://docs.snowflake.com/guides-overview-analysis). \n\n### Prerequisites\n- Working knowledge of SQL\n- A Snowflake account login with an ACCOUNTADMIN role. If not, you will need to use a different role that has the ability to create database, schema, table, stages, tasks, email integrations, and stored procedures. \n\n### What You\u2019ll Learn \n- How to make use of Anomaly Detection & Forecasting ML Functions to create models and produce predictions\n- Use Tasks to retrain models on a regular cadence\n- Use the [email notfication integration](https://docs.snowflake.com/en/user-guide/email-stored-procedures) to send email reports of the model results after completion \n\n### What You\u2019ll Build \nThis Quickstart is designed to help you get up to speed with both the Forecasting and Anomaly Detection ML Functions. \nWe will work through an example using data from a fictitious food truck company, Tasty Bytes, to first create a forecasting model to predict the demand for each menu-item that Tasty Bytes sells in Vancouver. Predicting this demand is important to Tasty Bytes, as it allows them to plan ahead and get enough of the raw ingredients to fulfill customer demand. \n\nWe will start with one food item at first, but then scale this up to all the items in Vancouver and add additional datapoints like holidays to see if it can improve the model's performance. Then, to see if there have been any trending food items, we will build an anomaly detection model to understand if certain food items have been selling anomalously. We will wrap up this Quickstart by showcasing how you can use Tasks to schedule your model training process, and use the email notification integration to send out a report on trending food items. \n\nLet's get started!" - }, - { - "cell_type": "markdown", - "id": "29090d0b-7020-4cc1-b1b4-adc556d77348", - "metadata": { - "name": "cell2", - "collapsed": false - }, - "source": "## Setting Up Data in Snowflake\n\n### Overview:\nYou will use Snowflake Notebook to: \n- Create Snowflake objects (i.e warehouse, database, schema, etc..)\n- Ingest sales data from S3 and load it into a snowflake table\n- Access Holiday data from the Snowflake Marketplace (or load from S3).

In a production setting, you may accordingly adjust the input table/view to have the most updated dataset to retrain the model.\n2. **Sending emails**: This requires you to set up an integration, and specify who the recipients of the email should be. When completed appropriately, you'll recieve an email from `no-reply@snowflake.net`, as seen below. \n3. **Formatting results**: We've made use of a snowpark stored procedure, to take advantage of the functions that pandas has to neatly present the resultset into an email. For futher details and options, refer to this [medium post](https://medium.com/snowflake/hey-snowflake-send-me-an-email-243741a0fe3) by Felipe Hoffa.\n4. **Executing the Tasks**: We have set this task to run the first of every month - if you would like to run it immediately, you'll have to change the state of the task to `RESUME` as shown in the last three lines of code above, before executing the parent task `AD_VANCOUVER_TRAINING_TASK`. Note that we have orchestrated the task to send the email to the user *after* the model has been retrained. After executing, you may expect to see an email similar to the one below within a few minutes.\n" - }, - { - "cell_type": "markdown", - "id": "c8112e22-b651-4e23-bcba-30fe2f3f9818", - "metadata": { - "name": "cell69" - }, - "source": "## Conclusion\n\n**You did it!** Congrats on building your first set of models using Snowflake Cortex ML-Based Functions. \n\nAs a review, in this guide we covered how you are able to: \n\n- Acquire holiday data from the snowflake marketplace\n- Visualized sales data from our fitictious company Tasty Bytes\n- Built out forecasting model for only a single item (Lobster Mac & Cheese), before moving onto a multi-series forecast for all the food items sold in Vancouver\n- Used Anomaly detection ML Function to identify anomalous sales, and used it to understand recent trends in sales data\n- Productionize pipelines using Tasks & Stored Procedures, so you can get the latest results from your model on a regular cadence\n\n### Resources: \nThis guide contained code patterns that you can leverage to get quickly started with Snowflake Cortex ML-Based Functions.

In practice, this means that they are often required to build models to: make forecasts, identify long running trends, and identify abnormalities within their data. However, Analysts are often impeded from creating the best models possible due to the depth of statistical and machine learning knowledge required to implement them in practice. Further, python or other programming frameworks may be unfamiliar to Analysts who write SQL, and the nuances of fine-tuning a model may require expert knowledge that may be out of reach. \n", + "\n", + "For these use cases, Snowflake has developed a set of SQL based ML Functions, that implement machine learning models on the user's behalf. As of December 2023, three ML Functions are available for time-series based data:\n", + "\n", + "1. Forecasting: which enables users to forecast a metric based on past values. Common use-cases for forecasting including predicting future sales, demand for particular sku's of an item, or volume of traffic into a website over a period of time.\n", + "2. Anomaly Detection: which flags anomalous values using both unsupervised and supervised learning methods. This may be useful in use-cases where you want to identify spikes in your cloud spend, identifying abnormal data points in logs, and more.\n", + "3.

It also includes the Snowpark ML API for more efficient ML modeling (public preview) and ML operations (private preview).\n\nFlexible Runtime Constructs: Snowpark provides flexible runtime constructs that allow users to bring in and run custom logic. Developers can seamlessly build data pipelines, ML models, and data applications with User-Defined Functions and Stored Procedures.\n\n### What is PyTorch?\n\nIt is one of the most popular open source machine learning frameworks that also happens to be pre-installed and available for developers to use in Snowpark. This means that you can load pre-trained PyTorch models in Snowpark for Python without having to manually install the library and manage all its dependencies.\n\nFor this particular application, we will be using [PyTorch implementation of MobileNet V3](https://github.com/d-li14/mobilenetv3.pytorch). *Note: A huge thank you to the [authors](https://github.com/d-li14/mobilenetv3.pytorch?_fsi=THrZMtDg,%20THrZMtDg&_fsi=THrZMtDg,%20THrZMtDg#citation) for the research and making the pre-trained models available under [MIT License](https://github.com/d-li14/mobilenetv3.pytorch/blob/master/LICENSE).*" + }, + { + "cell_type": "markdown", + "id": "d8a92fd3-e769-4950-b40d-321297d0c09b", + "metadata": { + "name": "_Prerequisites", + "collapsed": false + }, + "source": "### Prerequisites\n\n* Install `cachetools`, `pandas`, `streamlit` and `snowflake-snowpark-python` packages.

It's crucial to consider whether the procedure will run with caller's or owner's rights and manage dependencies by uploading necessary JAR files or resource files to Snowflake.

We covered creating and calling Java stored procedures and UDFs, performing asynchronous operations, handling unstructured data through file access, and returning tabular results using DataFrames. These tools allow you to extend Snowflake's capabilities with custom logic, parallelism, and integration with external data formats.\n\nAs you continue to develop with Java in Snowflake, consider how these features can help optimize your data workflows and unlock more complex processing scenarios. Whether you're encapsulating business logic, processing files at scale, or improving performance with parallel execution, Snowflake's support for Java gives you the flexibility to build scalable and maintainable solutions.\n\n### Resources\n\n- [Snowflake Java UDFs Documentation](https://docs.snowflake.com/en/developer-guide/udf/java/udf-java-introduction)\n- [Creating Stored Procedures in Java](https://docs.snowflake.com/en/developer-guide/stored-procedure/java/procedure-java-overview)\n- [Quickstarts](https://quickstarts.snowflake.com/)\n" + } + ] +} \ No newline at end of file diff --git a/Load CSV from S3/Load CSV from S3.ipynb b/Load CSV from S3/Load CSV from S3.ipynb index 5d23048..c38c3fa 100644 --- a/Load CSV from S3/Load CSV from S3.ipynb +++ b/Load CSV from S3/Load CSV from S3.ipynb @@ -1,231 +1,293 @@ { - "metadata": { - "kernelspec": { - "display_name": "Streamlit Notebook", - "name": "streamlit" - } - }, - "nbformat_minor": 5, - "nbformat": 4, "cells": [ { "cell_type": "markdown", "id": "13f35857-7833-4c7a-820b-421f7156fc94", "metadata": { - "name": "cell1", - "collapsed": false + "collapsed": false, + "name": "cell1" }, - "source": "# How to load CSV files from stage to Snowflake Notebooks \ud83d\udcc1\n\nIn this example, we will show how you can load a CSV file from stage and create a table with Snowpark. \n\nFirst, let's use the `get_active_session` command to get the [session](https://docs.snowflake.com/en/developer-guide/snowpark/reference/python/latest/api/snowflake.snowpark.Session#snowflake.snowpark.Session) context variable to work with Snowpark as follows:" + "source": [ + "# How to load CSV files from stage to Snowflake Notebooks ๐Ÿ“\n", + "\n", + "In this example, we will show how you can load a CSV file from stage and create a table with Snowpark. \n", + "\n", + "First, let's use the `get_active_session` command to get the [session](https://docs.snowflake.com/en/developer-guide/snowpark/reference/python/latest/api/snowflake.snowpark.Session#snowflake.snowpark.Session) context variable to work with Snowpark as follows:" + ] }, { "cell_type": "code", + "execution_count": null, "id": "4babf2c9-2d53-48dc-9b2e-07cda9bcc03c", "metadata": { - "language": "python", - "name": "cell2", + "codeCollapsed": false, "collapsed": false, - "codeCollapsed": false + "language": "python", + "name": "cell2" }, "outputs": [], - "source": "from snowflake.snowpark.context import get_active_session\nsession = get_active_session()\nprint(session)", - "execution_count": null + "source": [ + "from snowflake.snowpark.context import get_active_session\n", + "session = get_active_session()\n", + "# Add a query tag to the session.

This notebook demonstrates how to use Snowflake Cortex for creating a chatbot that can query parsed KubeCon session data. It starts by listing the staged files and parsing the session documents using the `PARSE_DOCUMENT` function to extract content. The parsed text is then chunked into smaller pieces using `SPLIT_TEXT_RECURSIVE_CHARACTER` to optimize it for search indexing. Afterward, a Cortex search service is created on the chunked content, and queries can be run against this service to retrieve relevant information. In the final step, Streamlit is used to build a chatbot interface, enabling users to interact with the system and ask questions about the parsed content.\n", + "\n", + "For more information on how to get started with Snowflake Cortex, including Retrieval Augmented Generation (RAG) applications, refer to the following links: \n", + "- [Snowflake Quickstarts](https://quickstarts.snowflake.com/) \n", + "- [RAG Applications with Snowflake](https://www.snowflake.com/en/fundamentals/rag/) \n", + "- [Cortex Search Overview](https://docs.snowflake.com/en/user-guide/snowflake-cortex/cortex-search/cortex-search-overview)" + ] + } + ], + "metadata": { + "kernelspec": { + "display_name": "Python 3 (ipykernel)", + "language": "python", + "name": "python3" + }, + "language_info": { + "codemirror_mode": { + "name": "ipython", + "version": 3 + }, + "file_extension": ".py", + "mimetype": "text/x-python", + "name": "python", + "nbconvert_exporter": "python", + "pygments_lexer": "ipython3", + "version": "3.12.7" + }, + "lastEditStatus": { + "authorEmail": "fawaz.ghali@snowflake.com", + "authorId": "5057414526494", + "authorName": "FAWAZG", + "lastEditTime": 1743684063913, + "notebookId": "a5udaqirmeklixc7tm4l", + "sessionId": "b19d4347-c938-4fe6-8c87-28d2a705aa99" + } + }, + "nbformat": 4, + "nbformat_minor": 5 +} diff --git a/README.md b/README.md index ecacb29..55b8e70 100644 --- a/README.md +++ b/README.md @@ -16,6 +16,24 @@ This repo contains a collection of Snowflake Notebook demos, tutorials, and exam + + + + Image + + +
