Re: Swap space
I see it is evicting the entries to swap. there was an email chain that says about memory leak in case of off-heap + swap + eviction. Do you remember and have any workaround ?

Re: Swap space
HI Val, When max heap is set, explicit eviction policy is not needed. correct ? Thanks.

Re: Swap space
An entry will go to swap only if it's evicted from the cache [1]. If eviction policy is not configured, this will never happen.

Re: Swap space
I think what he means is that no files are being created.. We are doing some tests with Ignite and we don't see any use of the cache, even when we load more keys than fit in physical memory. -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/Swap-space-tp8156p9112.html Sent from the Apache Ignite Users mailing list archive at Nabble.com.

Re: Swap space
Hi Vladislav,
i was trying swap space and see it is not working in unix but my test
program worked on windows.
i can swap folders but no files. Did you see any issue in the below
configuration ?
CacheConfiguration pConfig = new
CacheConfiguration();
pConfig.setName("Person_Cache");
pConfig.setIndexedTypes(String.class, Person.class);
pConfig.setBackups(1);
pConfig.setCacheMode(CacheMode.PARTITIONED);
pConfig.setCopyOnRead(false);
pConfig.setSwapEnabled(true);
pConfig.setMemoryMode(CacheMemoryMode.OFFHEAP_TIERED);
pConfig.setSqlOnheapRowCacheSize(100_000);
pConfig.setOffHeapMaxMemory(10 * 1024 * 1024 * 1024);
pConfig.setStartSize(200);
pConfig.setStatisticsEnabled(true);
and ignite.xml -
XX.XX.XX.1:47500..47509
XX.XX.XX.2:47500..47509
XX.XX.XX.3:47500..47509

Re: Swap space
Hi, You can to spy movement into swap space using Ignite event listener[1] on event EventType#EVT_SWAP_SPACE_DATA_EVICTED By default swap space directory is "swapspace" into working directory (if you configured IGNITE_HOME the directory placed in it in "work" sub-directory). You can configure this like: ... ...
