v0.9.2
c0f91b3

We are excited to release Jina 0.9.2. Jina is the easier way to do neural search in the cloud. Highlights of this release include:

  • Support for delete/update operations
  • Add native AsyncIO support and unlock native support for running Jina in Jupyter notebooks and IPython
  • Add MultiModalDocument as primitive types to support multimodal search in a Pythonic way
  • Refactor Pea and introduce Runtime to improve code readability and maintainability

Release 0.9.2

⬆️ Major Features and Improvements

Completeness

Click to see example

async_flow

from jina import AsyncFlow
with AsyncFlow().add(uses='_logforward') as f:
    await f.index_lines(lines=['hello', 'jina'], on_done=print)

Ease of Use

Click here for example code 
from jina import Document, MultimodalDocument
chunk_img = Document(modality='dummy_image', embedding=np.random.rand(1, 4))
chunk_text = Document(modality='dummy_text', embedding=np.random.rand(1, 10))
multimodal_doc = MultimodalDocument(chunks=[chunk_img, chunk_text])
  • Introduce Runtime as a member of Pea, defined as "a procedure that blocks the main process once running, therefore must be put into a separated thread/process. The new architecture greatly improves the readability and maintainability of the code. #1426, #1473, #1487, #1539, #1577

⚠️ Breaking Changes

  • Introduce UniqueId, ChunkSet, DocumentSet, MatchSet; Remove add_chunk and add_match; Refactor Document with newly introduced classes. #1343
Click here for example code
0.8.0 0.9.2 
from jina import Document()
with Document() as d:
    c = Document(id=f'1:0>16')
    d.chunks.append(c)

with Document() as d:
     c = d.chunks.append()
     c.id = f'1:0>16'    
from jina import Document()
with Document() as d:
    c = d.chunks.add_chunks()
    c.id = f'1:0>16'

  • Refactor YAML file parsing backend from ruamel.yaml to pyyaml and introduce jina.jaml for parsing YAML files. The dependency on ruamel.yaml is deprecated. #1495, #1516, #1524, #1533, #1547, #1581

  • Add _merge_matches and _merge_chunks for merging messages in different ways. Remove _merge_all. #1406 #1418

  • PyClient renamed to Client for simplicity #1450
