Architecture

Last Updated:2026-09-03 09:50:18

OceanBase Admin Toolkit (OAT) consists of the following components:

  • HTTP server: allows you to access OAT and perform operations by using a browser.
  • MetaDB: stores metadata of OAT and data of the task engines.
  • Scheduler and executor: the task engines of OAT, which support asynchronous, concurrent, and controllable O&M task processing.
