on GitHub

Double the transmission speed of search results to the client application through the following updates to gRPC:

• Optimize messages.
• Change the API of generated code.
• Remove compression.

Python SDK

• Divide the storage of search result ids and distances into separate arrays, which reduces the API response time.
• Add a new option to retrieve a specific target vector in search results: id = results.id_array[i][j], distance = results.distance_array[i][j].
• Add a new option for looping over arrays, which takes much less time if nq and topk is large.

  >> for id_list, dis_list in zip(results.id_array, results.distance_array):
  >>     for id, dis in zip(id_list, dis_list):
  >>        print("id={}, distance={}".format(id, dis))
  

Java SDK

• Add keepalive and idleTimeout settings when connecting to Milvus server.
• Now users can retrieve search result ids and distances separately through getResultIdsList and getResultDistancesList with better performance, or they can retrieve them together as a list of QueryResult objects through getQueryResultsList.

C++ SDK

• Now C++ SDK uses shared library.
• Add README file.

Enhance the search performance of IVF_SQ8H.
