Re: Continuous Query Questions

So, if I define the CQ as a service, and the node crashes, wouldn't ignite start a new service with CQ already registered, say if the CQ registration is in service init? I can do initial query at the as well. On Wed, Apr 1, 2020 at 7:33 PM Evgenii Zhuravlev wrote: > Well, with this use case,

Re: Continuous Query Questions

Well, with this use case, if one of the nodes goes down, there is always a chance to lost notifications. I don't think that it's possible to recover lost notifications with out of the box solution, but if you will be able to track the last processed notification and store update time in entries,

Re: Continuous Query Questions

Thanks Evgenii for the recommendation and the heads up. Is there a way to recover the lost notifications or even know if a notification is lost? On Wed, Apr 1, 2020 at 12:15 PM Evgenii Zhuravlev wrote: > Hi, > > 1) I would recommend checking ContinouousQuery.setLocal: >

Re: Continuous Query Questions

Hi, 1) I would recommend checking ContinouousQuery.setLocal: https://www.gridgain.com/sdk/ce/latest/javadoc/org/apache/ignite/cache/query/Query.html#setLocal-boolean-. Please check if it fits your requirements. 2) You will need to do this in a separate thread, because cache operations shouldn't

Re: Persistent dataregion config

Hi Andrey, Sorry, Looks like mixed up eviction policy for data region and Expiry Policy. Eviction Policy shouldn't work with persistence, it works only for in memory data regions. Evgenii -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/

Re: Ignite Web Session Clustering with standalone node

The way you connect to a single server or a cluster is the same. You need to define a “finder” and the way you do that — well, one of the ways — is to configure it in an XML file (https://apacheignite.readme.io/docs/tcpip-discovery ). In
