Together with the http://docs.jboss.org/jbpm/v5.3/userguide/ch.core-persistence.html#d0e3800 documentation section 8.3 , it said :   Storing history information in the runtime database can result in the database rapidly increasing in size, not to mention the fact that monitoring and analysis queries might influence the performance of your runtime engine. This is why process execution history information and runtime state should be stored separately. So , I want to ask inbest practice , we should   use 3 databases for the JBPM5 project ??? * A database  for storing runtime data which has the following tables only  : eventtypes , processinstanceinfo , sessioninfo , workiteminfo * A database for storing history information  (BAM purpose) which has the following tables only : nodeinstancelog, processinstancelog , processinstancelog * A database for the human task -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/756139#756139] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
