OceanBase
The team/company behind the OceanBase distributed SQL database — originally built at Ant Group to run Alipay and Taobao at scale — and the maker of seekdb, its Apache-2.0 agent state store. The pedigree is the credibility pitch for SeekDB: a database group with proven large-scale OLTP experience now targeting the agent-infrastructure market rather than building another harness. (Tracked lightly — this wiki’s interest is SeekDB as agent tooling, not OceanBase’s broader DB business.)
