Does Ignite enforce FULL_SYNC with Paxos ?

expect only one PutIfAbsent to succeed (returning true) and the other to fail (returning false), is it what happens ? If so, is it a Paxos algorithm that chooses only one of those 2 PutIfAbsent ? Thanks, Vincent "FINASTRA" is the trade name of the FINASTRA group of companies. This emai

Crash of Ignite (B+Tree corrupted) on a large PutIfAbsent

PutIfAbsent of 100 megabytes ? Anyway Ignite should probably not crash when this limit is exceeded. Please send a clean error instead like "Insertion request exceeds limit XYZ" and keep Ignite alive in this case. Regards, Vincent Semeria error : PerformanceAttribu

Re: Ignite Client getting OOM, GridAffinityProcessor grows in size

It looks like this happens when the connection is lost to the ignite servers from my clients. we use a internal vert.x event bus which seems to fail when ignite fails. Can it be that ignite does something to the thread when a disconnect happens. At first i had a vert.x event loop and merged the ev

Hi, When running for some time handling a constant load of 1.5K or more my application blows up with a OOM. org.apache.ignite.internal.processors.affinity.GridAffinityProcessor is taking up 96+% of memory in my application. It's a client so i do not undrestand why the application accumulates somet

Re: Apache Ignite vs alluxio

spark SQL thriftserver over ignite and cassandra

Hi, I am evaluating the possibility to use Spark SQL (and its scalability) over an Ignite cache with Cassandra persistent store to increase read workloads like OLAP style analytics. Is there any way to configure Spark thriftserver to load an external table in Ignite like we can do in Cassandra ? He
