Summary

TBase is Tencent-published, open-source database software for distributed hybrid transactional and analytical processing (HTAP). It combines database and data-warehouse services in one cluster and supports an extended subset of SQL, including transactions, foreign keys, user-defined types, and functions. TBase is compatible with PostgreSQL and is self-hosted: deployment guidance describes compiling from source and setting up a cluster across one or more hosts, including basic x86 servers. A cluster uses Coordinator Nodes to plan queries, DataNodes to hold user data, and a Global Transaction Manager. Tables can be distributed or replicated, and the system sends queries to DataNodes and gathers their results. Administrators can configure and manage clusters with pgxc_ctl. Table choices include shard, partitioned shard, hot-and-cold partitioned shard, and replication tables. Shard-table distribution-key values, lengths, and types cannot be changed. Replication tables keep a full copy on every DataNode, making them unsuitable for large tables and slower to update. Monitoring features include session memory, DataNode operator details, and cluster-wide active sessions. The software is free under the BSD 3-Clause License, with a listed third-party component exception.

Who it is for

TBase is suited to teams that need a self-hosted distributed database and data-warehouse cluster, with SQL capabilities and PostgreSQL compatibility. It may also suit administrators who want cluster management and query-monitoring tools.

What is good

  • Combines database and warehouse services in one cluster.
  • Supports transactions, foreign keys, types, and functions.
  • Tables can be distributed or replicated.
  • Includes cluster administration and monitoring features.
  • Free, open-source software under BSD 3-Clause.

What to know first

  • Shard-table distribution keys cannot be modified.
  • Replicated tables are unsuitable for large tables.
  • Replicated tables have low update performance.
  • Deployment involves compiling from source.

Verdict

TBase brings distributed database and warehouse services together, with self-hosted deployment and several table strategies. Consider the fixed shard distribution keys and replication limits when planning a cluster.
