Re: Ignite Node failure - Node out of topology (SEGMENTED)

We are still seeing the NODE SEGMENTATION issue happening to one of the node in our production even after JVM option is enabled ( -Djava.net.preferIPv4Stack=true). We don't see any activity reported in the logs for a period of ~30min after node failed. The below logs are from the failed node, and

IgniteCache.destory does delete CacheName*.dat file from persistent store directory

Hi, We are using Ignite 2.3 as distributed offheap persistent store to various caches in a cache group. When we create the cache, it creates the CACHENAME_cache_data.dat file and *.bin files in persistent store directory. After the use of cache, we are deleting the cache using IgniteCache.destory

RE: RDBMS as backend for Ignite SQL

Re: RDBMS as backend for Ignite SQL

Hi, You can use only one backed store per cache. I'm not sure, but very likely you will not be able to use cross-cache transaction for caches backed by different stores. Anyway, you can try. On Sat, Jun 9, 2018 at 1:15 PM, Michaelikus wrote: > Is it possible to use various RDBMS as persisted b

RE: Question on peer class loading

Hi, peerClassLoading only works for Ignite’s Compute Grid – i.e. for the tasks you send via ignite.compute() calls. Other classes, such as 3rd party libraries, need to be present on all nodes. Stan From: Dmitry Pavlov Sent: 9 июня 2018 г. 13:08 To: user; Vishwas Bm Subject: Fwd: Question on pee
