POSETTE: An Event for Postgres 2024 (formerly Citus Con) will happen virtually Jun 11-13, 2024. Call for Speakers is open! 💥
We released Citus 11 in the previous weeks and it is packed. Citus went full open source, so now previously enterprise features like the non-blocking aspect of the shard rebalancer—and multi-user support—are all open source for everyone to enjoy. One other huge change in Citus 11 is now you can query your distributed Postgres tables from any Citus node, by default.
When using Citus to distribute Postgres before Citus 11, the coordinator node was your application’s only point of contact. Your application needed to connect to the coordinator to query your distributed Postgres tables. Coordinator node can handle high query throughput, about 100K per second but your application might need even more processing power. Thanks to our work in Citus 11 you can now query from any node in the Citus database cluster you want. In Citus 11 we sync the metadata to all nodes by default, so you can connect to any node and run queries on your tables.
Running queries from any node is awesome but you also need to be able to monitor and manage your queries from any node. Before, when you only connected the coordinator, using Postgres’ monitoring tools was enough but this is not the case anymore. So in Citus 11 we added some ways to observe your queries similar to you would do in a single Postgres instance.Keep reading
