Re: Continuous query setPageSize and setTimeInterval question

Thanks Alex, But I still not quite understand the expected behaviour. If I set the page size to 100 and interval to 0, should the local query be triggered for every 100 updates? Regards, Rick -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/

Hi, setTimeInterval limits the time Ignite will wait for an internal buffer to fill up before sending. It is not a time delay setting. From the doc: https://ignite.apache.org/releases/latest/javadoc/org/apache/ignite/cache/query/ContinuousQuery.html#setTimeInterval-long- When a cach

Hello! According to documentation https://apacheignite.readme.io/docs/system-views ignite should expose the Node Metrics System View. However there is no such view in the code ( org.apache.ignite.spi.systemview.view package). Is it a peace of not-implemented-yet feature or is it a bug in the docum
