VectorEncoding class abstract final Query Enterprise Edition

A vector encoding to reduce the size of the vectors index by algorithmic compression.

This feature is only available in the Enterprise Edition.

You can configure the vector encoding to address your application’s needs.

This vector encoding compression reduces disk space required and I/O time during indexing and queries, but greater compression can result in inaccurate results in distance calculations.
