Info

When using data publisher API to publish data in a periodic manner to WSO2 BAMDAS/CEP, the eviction time and eviction idle time for the connections should be higher than the periodic interval. This is required to re-use the created socket connections from the pool, avoiding closure of it and creation of new connections. The default eviction period is 5.5 seconds (5500 milliseconds). If you are publishing events in a periodic interval as more than 5.5s, you need to tune the <secureEvictionTimePeriod> parameter accordingly, in the <PRODUCT<DAS_HOME>/repository/conf/data-bridge/thrift-agent-config.xml file of the agent in the client side, by increasing this default value.
