WSO2 CEP - Single Event Table for Multiple Execution PLans -


i have been exploring wso2 cep last couple of days.

i considering scenario single lookup table used in multiple execution plans. far know, way store data data event table.

my questions are:

  1. can load event table once(may 1 execution plan) , share table other execution plans?

  2. if answer of q1 no, multiple copies of same data storing in different execution plans, right ? there way reduce space utilization ?

  3. if event table not correct solution other options ?

thanks in advance, -obaid

event tables work in scenario. however, might need use rdbms eventtable or hazelcast eventtable instead of in-memory event tables. them, can share single table data multiple execution plans.

if want data preserved after server shutdown, should use rdbms eventtables (with can access table data using respective db browsers, i.e., h2 browser, mysql workbench, etc...). if want share single event table multiple execution plans @ runtime, can go ahead hazelcast eventtable.
