--node-count Worker node count of the cluster. When node count is 0, it represents a single node configuration with the ability to create distributed tables on that node. 2 or more worker nodes represent multi-node configuration. Node count value cannot be 1. Required for creation. --node...

Azure Cosmos DB for PostgreSQLis a distributed Postgres database service geared toward workloads that need a multi-node database cluster. Typical workloads for a distributed PostgreSQL database include multi-tenant SaaS, real-time analytics apps such as timeseries, and hybrid tra...
Hyperscale (Citus) so far was the cost and complexity of running a distributed database cluster, but this changes in Citus 10. With Citus 10 and the new Basic tier in Hyperscale (Citus), you can now shard your Postgres tables on a single Citus node to make your datab...
11, Citus extends pg_stat_activity via citus_stat_activity and citus_dist_stat_activity views. These views pull all the activity across the cluster, making it easier to examine the activity within the cluster. This becomes handy especially if your app is using the query from any node feature...
range partitioning to partition your tables by time ranges (super useful for time series data) and then—assuming your application needs more cpu and memory than you can get on a single node—you can also use Citus database sharding to distribute sharded partitions across a multi-node cluster....
Data Node数据节点是数据实际存储的地方。数据的分布可以由DBA来配置。为了提高可用性,可以配置数据节点的热备以便进行故障转移准备。 总结:gtm是负责ACID的,保证分布式数据库全局事务一致性。得益于此,就算数据节点是分布的,但是你在主节点操作增删改查事务时,就如同只操作一个数据库一样简单。Coordinator是调度的,将...
