Re: Re[2]: Ever increasing startup times as data grow in persistent storage

Thank Zhenya. Currently we call Ignition.Stop() with the flag to allow jobs to complete. I assume when using deactivate we don;t need to call that, or is it still a good idea as a belt and braces shut down for the grid? Raymond On Wed, Jan 13, 2021 at 8:28 PM Zhenya Stanilovsky wrote: > > > >

Hi Zhenya, Thanks for confirming performing checkpoints more often will help here. I have established this configuration so will experiment with settings little. On a related note, is there any way to automatically trigger a checkpoint, for instance as a pre-shutdown activity? Checkpoints seem t

Re: Ever increasing startup times as data grow in persistent storage

Hi Naveen, We currently have two data regions. A small one (for ingest), set to 128 Mb, and a larger one for requests (4Gb). We leave the checkpoint page buffer size at the default value, so this will be 1Gb for the larger region, and possibly 128Mb for the smaller region (if I recall the rules co

Re: Ever increasing startup times as data grow in persistent storage

Hi Raymond Did you try checkpointPageBufferSize instead of time interval, we have used 24MB as checkpointPageBufferSize , working fine for us, we also have close to 12 TB of data and does take good 6 to 10 mts to bring up the node and become cluster active Regarding the no of partitions also, 128

Ever increasing startup times as data grow in persistent storage

We have noticed that startup time for our server nodes has been slowly increasing in time as the amount of data stored in the persistent store grows. This appears to be closely related to recovery of WAL changes that were not checkpointed at the time the node was stopped. After enabling debug log

Okay, thanks Ilya . After it gets this issue, the app doesnt startup till I restart my server nodes. Is there anyway I can ensure clean shutdown when I face issues like this ? It looks like some ignite state is not cleaned up . regards, Veena. -- Sent from: http://apache-ignite-users.70518

Hi, You don’t have to specify the communication settings explicitly, usually it’s ok to leave the defaults.
