Re: Using more memory than is physically available

If you don't want to lose the data, which doesn't fit in RAM, on restarts then go for Ignite persistence. If it's fine to lose the data on restarts then the OS swapping is a good option as well: https://apacheignite.readme.io/docs/swap-space -- Denis On Thu, Aug 9, 2018 at 2:33 PM

Transaction Throughput in Data Streamer

Using more memory than is physically available

Will Apache Ignite allow me to use more memory than is physically available on my system? If yes, Do I need to turn persistence on? If I do not need to turn persistence on , how do I specify the location on disk to which memory will be swapped? -- Sent from:

Proper config for IGFS eviction

I've been struggling to find a configuration that works successfully for IGFS with hadoop filesystem caching. Anytime I attempt to load more data than what will fit into memory on my Ignite node, the ignite process crashes. The behavior I am looking for is that old cache entries will be

Re: continous query remote filter issue

Hello! I have just created sample project with your code (by running two standalone nodes with peerAssemblyLoadingMode="CurrentAppDomain" as well as one client with project code) and it runs just fine. Both Hello World closure and filter are executed just fine. This is slightly puzzling to me,

Re: affinity key field not recognized c++

Hello! I am pretty confident that affinity key configuration is supported by C++. There is one error in your configation file: you are using Simple Mapper, but still specify package of class in question. This causes weird behavior on Ignite side, but is trivial to fix: After that,

Re: H2 performs better than ignite !!?

Hello! The expectation is that distributed grid will inherently work slower on single node than dedicated DB. However, distributed grid will also work on multiple node, when traditional DB wouldn't. So extracting every last bit of single-node performance takes a back seat when also considering

Re: H2 performs better than ignite !!?

Yes, I am running on a single node. Still ignite being in-memory, I expected it to perform better than H2. Is there anything I can do to make it faster? Like right now I have a single data region, does having multiple data regions give me better performance? Something like that? -- Sent from:

Re: Hibernate L2 cache with Ignite. How?

Hi, Are you sure that you access the same cache that is used for l2? Try to invoke Ignite.cacheNames() - it will give you a list of caches in the cluster, using that, you can check that use right cache. Evgenii -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/

Re: Partitions distribution across nodes

Hi Akash, 1) Actually exchange is a short-time process when nodes remap partitions. But Ignite uses late affinity assignment, that means affinity distribution will be switched after rebalance completed. In other words after rebalance it will atomically switch partition distribution. But you don't
