Hi igniters! Using data streamer from compute tasks may cause starvation, because both operations are executed in the same public pool. Is it possible to add configuration for separate thread pool for data streamer? Thanks! Dmitry.

Hi Binti, Probably the issue is related to the fact that you’re working with the cache inside of CacheStore.writeAll method. Have you tried to use PESSIMISTIC/REPEATABLE_READ mode? Is the situation the same? Please attach thread dumps from all the nodes after the hang is reproduced one more tim

Hi Pradeep, Member-member (server-server) performance is better than client-server one in the scenario because in the first case roughly a half of data will be stored on the server that executes the benchmark (meaning that there won’t be I/O at all). While in case with client-server case the cl

Re: Ignite client reads old metadata even after cache is destroyed and recreated
