Method Detail

getKey

public String getKey()

allowExecution

public Boolean allowExecution()

If this node is allowed to execute timers. If this is false then the timers will be added to the database, and another node may execute them. Note that depending on your refresh interval if you add timers with a very short delay they will not be executed until another node refreshes.

allowExecution

public DatabaseDataStore allowExecution(Boolean value)

If this node is allowed to execute timers. If this is false then the timers will be added to the database, and another node may execute them. Note that depending on your refresh interval if you add timers with a very short delay they will not be executed until another node refreshes.

datasourceJndiName

public String datasourceJndiName()

The datasource that is used to persist the timers

datasourceJndiName

public DatabaseDataStore datasourceJndiName(String value)

The datasource that is used to persist the timers

partition

public String partition()

The partition name. This should be set to a different value for every node that is sharing a database to prevent the same timer being loaded by multiple noded.

partition

public DatabaseDataStore partition(String value)

The partition name. This should be set to a different value for every node that is sharing a database to prevent the same timer being loaded by multiple noded.

refreshInterval

public Integer refreshInterval()

Interval between refreshing the current timer set against the underlying database. A low value means timers get picked up more quickly, but increase load on the database.

refreshInterval

public DatabaseDataStore refreshInterval(Integer value)

Interval between refreshing the current timer set against the underlying database. A low value means timers get picked up more quickly, but increase load on the database.
