Release notes

The latest product updates from Neon

Storage and Compute release

What's new

  • Compute: Added support for sequential scan prefetch, which reduces round trips between Computes and Pageservers. Sequential scan prefetch allows fetching numerous pages at once instead of one by one, improving I/O performance for operations such as table scans.
  • Compute: Added support for the pg_prewarm PostgreSQL extension, which utilizes the above-mentioned sequential scan prefetch feature. The pg_prewarm extension provides a convenient way to load data into the PostgreSQL buffer cache after a cold start. For information about PostgreSQL extensions supported by Neon, see PostgreSQL extensions.
  • Compute: Updated supported PostgreSQL versions to 14.6 and 15.1, respectively.
  • Pageserver: Updated the storage_sync operation to make it more robust and reliable while syncing files between Pageservers and S3.
  • Safekeeper: Replaced etcd subscriptions with a custom Neon storage broker. The storage broker allows Safekeepers and Pageservers to learn which storage node holds a timeline and the status of a timeline while avoiding too many connections between nodes.
