Re: IgniteOutOfMemoryException in LOCAL cache mode with persistence enabled

For the requested full ignite log, where would this be found if we are running using local mode? We are not explicitly running a separate ignite node, and our WorkDirectory does not seem to have any logs From: user@ignite.apache.org At: 12/03/19 19:00:18To: user@ignite.apache.org Subject: Re:

Re: IgniteOutOfMemoryException in LOCAL cache mode with persistence enabled

For our configuration properties, our DataRegion initialSize and MaxSize was set to 11 MB and persistence was enabled. For DataStorage, our pageSize was set to 8192 instead of 4096. For Cache, write behind is disabled, on heap cache is disabled, and Atomicity Mode is Atomic From:

Re: Expected serialization performance of Ignite .NET

Ok thanks. I have managed to get the times down to 13 seconds write and 7.5 seconds read, basically double your times, on my 12 processor Intel i7-8850 laptop which is running 100% so you must have some good kit! Does Java version have any bearing on performance? -- Sent from:

What is the purpose of indexes in Cassandra table when they can not be queried?

Hi, I am using Cassandra Ignite integration. In this integration, one is able to provide specific "mapping" in persistence xml so a key is e.g. a primitive and value is POJO. Now, I was quite surprised (as a lot of other people too as I read more about this), that it is not possible to do SQL

Re: IgniteOutOfMemoryException in LOCAL cache mode with persistence enabled

Hi Mitchell, Looks like it could be easily reproduced on low off-heap sizes, I tried with simple puts and got the same exception: class org.apache.ignite.internal.mem.IgniteOutOfMemoryException: Failed to find a page for eviction [segmentCapacity=1580, loaded=619, maxDirtyPages=465,

IgniteOutOfMemoryException in LOCAL cache mode with persistence enabled

We are running Ignite in LOCAL mode currently and have persistence enabled. For this specific test, the off heap memory was set to as low as possible (~10 MB) to test on-disk performance. We have multiple caches sharing the same DataRegion. For the test, we basically write synchronously to

Re: Expected serialization performance of Ignite .NET

I've tried your code and got similar numbers (11s to write, 3s to read). Profiler shows that serialization takes 90% of the streaming time (40% is your WriteBinaryInternal method, the rest is Ignite internals) Actual size of serialized object is 161 bytes, and DataRegionMetris.TotalAllocatedSize

Hi Ivan, Thank you for the confirmation. In the link, I can see that the issue will be resolved in Ignite 3.0 version. When will Ignite 3.0 be released? Is there any tentative date? Regards, Shravya Nethula, BigData Developer, [cid:2a5e6893-c131-4622-bebf-2deef20e1f50] Hyderabad.

Hello! I've re-checked your case, and I think it's due to the known issue https://issues.apache.org/jira/browse/IGNITE-11161 This is because of incorrect default in Thin Client. You need to change the following: ClientConfiguration cfg = new ClientConfiguration().setAddresses(HOST + ":" +
