Andrey,
Yes it is a little bit complicated for understanding.
CacheConfiguration.evictionPolicy takes it roots back in history where
there were neither offheap nor persisence, cache data was stored in
java heap only. Also, as far as I know, today
CacheConfiguration.evictionPolicy (as already
Hello!
Data is always written to persistence immediately (via WAL). You can
control eviction of offheap with evictionThreshold and pageEvictionMode
settings of DataRegionConfiguration.

When data overfit dataRegion max size, so no more available offheap space,
then data goes to persistence. So, what option controls how data pages
should be evicted from offheap to persistence.

Hello!
Data is always stored in offheap. Eviction strictly controls onheap cache.
Once data is evicted from onheap it is available in offheap.

We plan to use persistence in production. I didn't understand,
CacheConfiguration.EvictionPolicy specify heap->offheap eviction,
offheap->persistence eviction or both. It's not clear for me.

No, we didn't specify EvictionPolicy. I didn't find does CacheConfiguration
have default EvictionPolicy?

Hello!
Oops, I was wrong. This is indeed the wrong setting.
Have you tried specifying evictionPolicy? I think it is the one that
controls eviction from onheap cache. You can put a LruEvictionPolicy of 100
000 here, for example.

No, because we didnt specify QueryEntity.
Does onheapCacheEnabled uses for SQL only?
What default value for sqlOnheapCacheMaxSize?

Hello!
Have you tried also specifying sqlOnheapCacheMaxSize? You can specify 100
000 if you like.

We use simple replicated KV cache.
We try to upload 32 000 000 small records to it (about 6Gb in
data region, persistance disabled). We load data using DataStreamer.
If we set onheapCacheEnabled=false, server node consumes heap about 500 Mb.
If we set onheapCacheEnabled=true, server node
12 matches
