Hi When I looked at the sample code you have sent, I believe you have misunderstood the way Siddhi Snapshot works.
Siddhi does not restore the queries or definitions when restoring, but it will only restore the states on each query (e.g the partially matched states in sequence/pattern query, events in windows, running average values, etc..). Here on your setup method, you have to create the Siddhi Manager and add the Stream Definitions, Queries and then restore the state. You can find a sample test case here https://github.com/wso2-dev/siddhi/blob/master/modules/siddhi-core/src /test/java/org/wso2/siddhi/test/management/PersistenceTestCase.java Regards Suho On Mon, Sep 1, 2014 at 7:20 PM, Antonio Jesus Navarro <ajnava...@stratio.com > wrote: > Hi all, > > I could not fix the problem. > > Someone can explain me what i'm doing wrong? > > Thanks in advance. > > > 2014-08-13 9:53 GMT+02:00 Antonio Jesus Navarro <ajnava...@stratio.com>: > > Hi Rajeev and Tishan, >> >> I add a couple of tests to show the two possible use cases described, one >> using PersistenceStore implementation, and other using snapshot() and >> restore(...)
