Qdrant 1.9.0 - Heighten Your Security With Role-Based Access Control Support - Qdrant

What this post added

This post introduces granular access control using JSON Web Tokens (JWT) to implement Role-Based Access Control (RBAC), allowing users to define permissions and restrict access to specific data segments and endpoints. It also details the `wal_delta` method for faster shard transfers during node recovery, which leverages Write-Ahead Logs (WAL) to transmit only differential data. Additionally, native support for `uint8` embeddings is added, enabling 4x memory savings and ~30% search speed-up by using pre-quantized embeddings.
