Stolon from 3 The main parts are

• keeper： It manages a PostgreSQL The example converges to that calculated by the leader sentry clusterview.
• sentinel： It detects and monitors keepers and proxy, And calculate the best clusterview.
• proxy： Client access point . It forces the connection to the correct PostgreSQL Lord The server And force the connection to the old master server to be closed .

Stolon Is a PostgreSQL High availability cloud native PostgreSQL Manager . It's cloud native , Because it allows you to Containers in （kubernetes Integrate ） And all other types of infrastructure （ cloud IaaS、 Old infrastructure, etc ） Maintain high availability on PostgreSQL.

function

• utilize PostgreSQL Streaming replication .
• Adapt to any type of partition . While trying to maintain maximum availability , It prefers consistency to usability .
• kubernetes Integration enables you to postgreSQL High availability .
• Use etcd、consul or kubernetes API server And other cluster storage as highly available data storage and storage leader The election .
• asynchronous （ Default ） And synchronous replication .
• Complete cluster setup in a few minutes .
• Easy and simple cluster management .
• With your preferred backup / Recovery tool integration for point in time recovery .
• Standby cluster （ For multi site replication and migration with near zero downtime ）.
• Automatic service discovery and dynamic reconfiguration （ Handle postgres and stolon The process changes its address ）.
• have access to pg_rewind With the current master Fast instance resynchronization .
