FREE ChronicDB v2: Live schema changes with zero downtime for PostgreSQL - Mailing list pgsql-announce

We would like to announce the release of ChronicDB v2.2.2, which supports PostgreSQL. ChronicDB offers live schema changes with zero downtime including live database updates in the presence of active queries[1,2].

ChronicDB v2 accounts for in-progress transactions and applies a live database update only when it can be guaranteed that data consistency will be preserved. Updates are applied atomically within a configurable timeout period, eliminating the possibility for long-lived transactions to introduce permanent unavailability. This is accomplished by a combination of replication, live connection migration, and query rewritting.

We are celebrating this release by offering a FREE copy of ChronicDB[3] for the next two weeks. We also invite community feedback on improving live database updates[4] and making the technology more accessible to the PostgreSQL community.
