Re: Full GC happening during rebalancing

Hi, I have not been able to get the heap dump after oom (it is not opening from mat or jhat) but I am repeating my experiment and just took the heap dump when one of the ignite servers is at 2 gb out of 5 gb. This is what the mat extract tells me 80 instances of "org.apache.ignite.internal.util.

I have a question. our company system uses Ignite1.9 version. we made the topology with 8 nodes.(01-08) In our business logic, every one minute all nodes have to check other nodes status each other by Ignite ping . when 02_node sent ignite ping to the 06_node, the exception was occured. Excep

Ignite SparkSQL need to pre-load data?

I want to find how to speed up SparkSQL using Ignite (in particular I am wondering if it can be a replacement for Presto and my files are parquet format in S3). Question: Reading from the links in https://ignite.apache.org/use-cases/spark/sql-queries.html, is it true (in my case) I need to pre-lo

Do elements with EternalExpiryPolicy in cache ever get evicted?

Hi, I am on Ignite version 2.5, not using Ignite persistence, and I have some data in a cache which I want to keep around in memory so I've set up an EternalExpiryPolicy on the particular cache. Will this stay in memory then so my cache queries will work (provided I have enough memory)? I really

SQL performance very slow compared to KV in pure-in-memory cache?

Hi, I was trying to benchmark ignite for with YCSB in both KV and SQL model. Ignite is 2 node cluster with 4CPU and 24GB ram and capable 10Gig n/w cards. Persistance=false(disabled) and backup=1 With this setup, when i ran ycsb for insert and read operations i get following: 1) 100% insert perf

Partitions stuck in MOVING state after upgrade to 2.7

Iterating through native persistence entries before joining the cluster

Hi, in our use case we need to run some C++ code (via JNI) whenever something is pushed into the local Ignite cache. In other words, we need to have Ignite in sync with C++ memory. We have a local listener that listens to EVT_CACHE_OBJECT_PUT events and executes the C++ code, so everything is fine

Re: Ignite .NET in docker (linux)?
