Release notes

The latest product updates from Neon

Storage release

What's new

  • Pageserver: Increased the default compaction_period setting to 20 seconds to reduce the frequency of polling that is performed to determine if compaction is required. The frequency of polling with the previous setting of 1 could result in excessive CPU consumption when there are numerous tenants and projects.
  • Pageserver: Added initial support for online tenant relocation.
  • Pageserver: Added support for multiple PostgreSQL versions.
  • Compute: Added support for the h3_pg and plv8 PostgreSQL extensions. For information about PostgreSQL extensions supported by Neon, see Available PostgreSQL extensions.
  • Compute: Added support for a future implementation of sequential scan prefetch, which improves I/O performance for operations such as table scans.
  • Compute: Moved the backpressure throttling algorithm to the Neon extension to minimize changes to the Neon PostgreSQL core code, and added a backpressure_throttling_time function that returns the total time spent throttling since the system was started.
  • Proxy: Improved error messages and logging.
