Has anyone benchmarked the write-throttling? Would be nice to see the CPU and memory graphs. On Thu, Nov 16, 2017 at 12:03 AM, Ivan Rakov wrote: > I agree. > > Moreover, peak throughput after long idle period won't be decreased. > Throttling works only during ongoing checkpoint (and probability

I agree. Moreover, peak throughput after long idle period won't be decreased. Throttling works only during ongoing checkpoint (and probability of checkpoint running after idle period is very low). Best Regards, Ivan Rakov On 16.11.2017 10:52, Dmitry Pavlov wrote: Yes, it is correct. But st

Yes, it is correct. But still, right after implementation I was for enabling this mode by detault. - It is not simple to explain need to enable this feature to each user. - Moreover write freezing after peak load may be considered by some Ignite users as bug. Not all of them will write to user lis

AFAIK throttling may decrease peak throughput. Alex, Ivan, Is it correct? On Thu, Nov 16, 2017 at 1:12 AM, Dmitriy Setrakyan wrote: > Thanks Denis, looks very nice! > > Igniters, let's stop asking users to enable flags in order for the system > to behave properly. All such flags should be enabl

Thanks Denis, looks very nice! Igniters, let's stop asking users to enable flags in order for the system to behave properly. All such flags should be enabled by default. D. On Wed, Nov 15, 2017 at 11:26 AM, Denis Magda wrote: > Igniters, > > I finished documenting pages write throttling and ch

Igniters, I finished documenting pages write throttling and checkpointing buffers adjustment sections under the performance notes: https://apacheignite.readme.io/docs/durable-memory-tuning#section-pages-writes-throttling https://apacheignite.readme.io/docs/durable-memory-tuning#section-checkpoint
