Version control executor parameters

Spring common parameters

ParameterEnvironment VariableDefault ValueDescription
spring.main.web-environment WEB_APPLICATION_ENABLE false If you enabled process metrics you should also enable 'web-environment'.
spring.main.web-application-type WEB_APPLICATION_TYPE none If you enabled process metrics you should set 'web-application-type' to 'servlet' value.
spring.main.allow-circular-references "true" Spring Boot configuration property that controls whether circular dependencies between beans are allowed.

Server common parameters

ParameterEnvironment VariableDefault ValueDescription
server.address HTTP_BIND_ADDRESS Server bind address (has no effect if web-environment is disabled).
server.port HTTP_BIND_PORT 8086 Server bind port (has no effect if web-environment is disabled).

Zookeeper connection parameters. Used for service discovery.

ParameterEnvironment VariableDefault ValueDescription
zk.enabled ZOOKEEPER_ENABLED true Enable/disable zookeeper discovery service.
zk.url ZOOKEEPER_URL localhost:2181 Zookeeper connect string
zk.retry_interval_ms ZOOKEEPER_RETRY_INTERVAL_MS 3000 Zookeeper retry interval in milliseconds
zk.connection_timeout_ms ZOOKEEPER_CONNECTION_TIMEOUT_MS 3000 Zookeeper connection timeout in milliseconds
zk.session_timeout_ms ZOOKEEPER_SESSION_TIMEOUT_MS 3000 Zookeeper session timeout in milliseconds
zk.zk_dir ZOOKEEPER_NODES_DIR /thingsboard Name of the directory in zookeeper 'filesystem'
zk.recalculate_delay ZOOKEEPER_RECALCULATE_DELAY_MS 0 The recalculate_delay property is recommended in a microservices architecture setup for rule-engine services. This property provides a pause to ensure that when a rule-engine service is restarted, other nodes don't immediately attempt to recalculate their partitions. The delay is recommended because the initialization of rule chain actors is time-consuming. Avoiding unnecessary recalculations during a restart can enhance system performance and stability.
