Timescale's new Livesync feature enables real-time data analytics with Postgres databases without downtime or risk. It streams data from any Postgres, including those on RDS or Azure, into Timescale Cloud, optimizing it for analytical workloads. Livesync employs the logical replication protocol to achieve high-throughput ingestion and enhances data preparedness with features like hypertables. It maintains full operational continuity of source systems while enabling fast analytics and potential future migration to Timescale.
