Re: Getting Baseline Topology Error

Hi, When do you usually change the baseline topology? It looks like you changed topology for part of the nodes and the changed it for another node separately, so now they have different baseline topologies. Do you have nodes for runs before this issue happened? Thanks, Evgenii чт, 14 мая 2020

Re: SQL execution performance problems due to insufficient off-heap space

The base rule is keep at 4K unless there is a very good reason to change it. See here: https://apacheignite.readme.io/docs/durable-memory-tuning#page-size also try to turn on direct IO: https://apacheignite.readme.io/docs/durable-memory-tuning#enabling-direct-io small page sizes might cause

Re: SQL execution performance problems due to insufficient off-heap space

Hi, I tested and found that pageSize can be configured up to 16K. If 4K, 8K and 16K are configured respectively, the read performance will increase linearly, but the write performance will decrease linearly, and the disk space occupation of persistent files will also increase significantly.

Re: ignite node ports

If you download Ignite and run it, the REST server isn’t enabled. You have to copy ignite-rest-http from libs/optional to libs. Assuming you did that, you can start Ignite like this: ./ignite.sh -J-DIGNITE_JETTY_PORT=8088 That will start the REST service on port 8088. > On 14 May 2020, at

No, it needs to be able to determine which node the data should be on without reference to anything else. This means that you’d need company-id in your address table. > On 13 May 2020, at 21:23, narges saleh wrote: > >  > My other question is whether affinity is transitive. > Company
