Fixes & improvements
- Compute: Added support for the Postgres
plcoffeeextensions. For more information about Postgres extensions supported by Neon, see Postgres extensions.
- Pageserver: Added an experimental feature that automatically evicts layer files from Pageservers to optimize local storage space usage. When enabled for a project, Pageservers periodically check the access timestamps of the project's layer files. If the most recent layer file access is further in the past than a configurable threshold, the Pageserver removes the layer file from local storage. The authoritative copy of the layer file remains in S3. A Pageserver can download a layer file from S3 on-demand if it is needed again, to reconstruct a page version for a client request, for example.
- Proxy: Significantly reduced network latencies for WebSocket and pooled connections by implementing caching mechanism for compute node connection information and enabling the
TCP_NODELAYprotocol option. The
TCP_NODELAYoption causes segments to be sent as soon as possible, even if there is only a small amount of data. For more information, refer to the TCP protocol man page.
