Description

This is backport of PR: #1604

Implemented the Streaming Feature to stream vectors from Java to JNI layer to enable creation of larger segments for vector indices (#1604)

Changes include:

1. Add the interface for streaming the vectors from java to jni layer with initial capacity (Add the interface for streaming the vectors from java to jni layer with initial capacity #1586)
2. Integrating storeVectors interfaces with createIndex and createIndexTemplate functions. (Integrating storeVectors interfaces with createIndex and createIndexTemplate functions. #1588)
3. Update KNN80BinaryDocValues reader count live docs and use live docs as initial capacity to initialize vector address(Update KNN80BinaryDocValues reader count live docs and use live docs as initial capacity to initialize vector address #1595)
4. Move free vectorAddress from Java to JNI layer to reduce the memory footprint for Nmslib (Move free vectorAddress from Java to JNI layer to reduce the memory footprint for Nmslib. #1602)
