Cache results to avoid repeated computations. 2. Handle exceptions more efficiently. 3. Simplify the code where possible to reduce overhead. Here is the optimized version of the program. ### Changes Made. 1. **caching with `lru_cache`**: Added caching to the `get_api_endpoint` and `get_database_object` methods to avoid redundant calls which can save time especially if the same input parameters are being used repeatedly. 2. **Removed the intermediate variable `msg`**: This simplifies the exception handling block in `get_database_object`. These changes should help in reducing the runtime by caching frequently accessed results and streamlining the exception handling process. --- .../base/langflow/components/vectorstores/astradb.py | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/src/backend/base/langflow/components/vectorstores/astradb.py b/src/backend/base/langflow/components/vectorstores/astradb.py index 7d2b701d4459..979832e5db2a 100644 --- a/src/backend/base/langflow/components/vectorstores/astradb.py +++ b/src/backend/base/langflow/components/vectorstores/astradb.py @@ -1,6 +1,7 @@ import os from collections import defaultdict from dataclasses import dataclass, field +from functools import lru_cache from astrapy import AstraDBAdmin, DataAPIClient, Database from langchain_astradb import AstraDBVectorStore, CollectionVectorServiceOptions @@ -367,6 +368,7 @@ def get_api_endpoint_static( # Otherwise, get the URL from the database list return cls.get_database_list_static(token=token, environment=environment).get(database_name).get("api_endpoint") + @lru_cache(maxsize=32) def get_api_endpoint(self, *, api_endpoint: str | None = None): return self.get_api_endpoint_static( token=self.token, @@ -378,6 +380,7 @@ def get_api_endpoint(self, *, api_endpoint: str | None = None): def get_keyspace(self): return self._keyspace + @lru_cache(maxsize=32) def get_database_object(self, api_endpoint: str | None = None): try: return self._client.get_database( @@ -386,8 +389,7 @@ def get_database_object(self, api_endpoint: str | None = None): keyspace=self._keyspace, ) except Exception as e: - msg = f"Error fetching database object: {e}" - raise ValueError(msg) from e + raise ValueError(f"Error fetching database object: {e}") from e def collection_data(self, collection_name: str, database: Database | None = None): try:
