## Tenant monitoring in Citus 11.3 Now you can monitor the tenants of your multi-tenant SaaS application. Use citus_stat_tenants to quickly locate the noisy neighbor in your cluster. Also in 11.3, execute shard moves in parallel from different co-location groups, and MERGE between co-located, distributed tables. Plus improved metadata syncing for very large numbers of tables. Read [Marco’s blog post](https://www.citusdata.com/blog/2023/05/05/whats-new-in-citus-11-3-multi-tenant-saas/#parallel-shard-rebalancing) for all the info. Or if you’re more interested in the code you can check out the [Citus database GitHub repo](https://github.com/citusdata/citus) (feel free to give the project a star to show support :).)
