MySQL vs TBase

MySQL has no write-up on Specifiction yet; its figures are above.

TBase is Tencent-published, open-source database software for distributed hybrid transactional and analytical processing. It provides database and data warehouse services through one cluster and supports an extended subset of SQL, including transactions, foreign keys, user-defined types, and functions. A cluster uses Coordinator Nodes to plan queries, DataNodes to store user data, and a Global Transaction Manager. Tables can be distributed or replicated, with queries sent to DataNodes and results gathered. Deployment is self-hosted; setup guidance describes compiling from source and deploying across one or more hosts, including basic x86 servers. Administrators can use pgxc_ctl to configure and manage clusters. Table options include shard, partitioned shard, hot-and-cold partitioned shard, and replication tables. Shard-table distribution-key values, lengths, and types cannot be modified. Replication tables keep a full copy on every DataNode, and the guide cautions against using them for large tables. Monitoring includes session memory, DataNode operator details, and cluster-wide active sessions. TBase is listed as free under the BSD 3-Clause License.
