This topic describes the terms that are used in OceanBase Admin Toolkit (OAT).
OAT: a platform that is used to install and manage services and components in the OceanBase ecosystem.
OceanBase Database: a distributed relational database that supports the MySQL and Oracle modes.
ecosystem services: the services in the OceanBase ecosystem, including OceanBase Cloud Platform (OCP), OceanBase Developer Center (ODC), OceanBase access proxy (OB Sharding), and OceanBase Migration Service (OMS).
- OCP: a platform that is used to manage OceanBase clusters.
- ODC: a platform for database development.
- OMS: a service for data exchange between homogeneous or heterogeneous data sources and OceanBase Database.
- OB Sharding: a dedicated proxy service of OceanBase Database. OB Sharding receives SQL requests from users, forwards them to the optimal server, and then returns the execution results to users.
components: the components of OceanBase Database, including MetaDB, OBDNS, and InfluxDB.
- MetaDB: a container-based OceanBase Database service that is built in with an OceanBase proxy for external access. It stores the metadata of services such as OCP, ODC, and OMS.
- OBDNS: a DNS and Tengine-based load balancing service that is deployed by using a container. If no external load balancing devices such as F5 are available, you can use OBDNS as a software load balancer. However, you must set the DNS server to the server on which OBDNS resides on your client. OBDNS provides load balancing and high availability capabilities for OceanBase ecosystem services such as OCP.
- InfluxDB: a container-based time-series database service that stores monitoring data for data transmission in OMS.
- Network Load Balancer (NLB): an OpenResty-based load balancer that features high availability, simple deployment, and low resource consumption. It provides load balancing capabilities for OceanBase ecosystem services such as OCP, ODC, and OMS.
tools: the extended O&M tools available upon delivery. Only OBLB is available.
- OBLB: an iptables-based load balancing service. If no external load balancing devices such as F5 are available and the traffic is light, you can use OBLB as the software load balancer for OceanBase clusters.
