Re: how to loadCache from Hbase

Hi, There is no example particularly for HBase, but it's no different from other implementations - you need to implement CacheStore interface and provide it in configuration. I would start with extending convenient CacheStoreAdapter class and implementing load/write/delete methods, like shown

Re: Client fails to connect - joinTimeout vs networkTimeout

Hi, You can limit the size of the allocated off heap memory for a cache by setting CacheConfiguration.offHeapMaxMemory property. If it's exceeded, entries will start to evict from cache on LRU basis. If you have a persistence store, it will then loaded from from there. Otherwise, you lose the

Re: java.lang.OutOfMemoryError in normal Ignite usage

1GB of heap is generally very small. The memory issue may or may not be related to Ignite. I would suggest increasing the heap size and check the heap graphs in any profiler, to make sure that it is not constantly growing without being reclaimed. If it is, then I would check which objects are the

Cluster Stopped when no activity for hours

Hi Team, I have a ignite cluster with 11 nodes, and I have four partitioned caches all using off heap memory. I want to load several GBs of data into the caches (each node is 256GB RAM). I use loadCache API to load, and it takes a lot of time to load the data into cache. I leave the cluster as

Val, we are going to try 10 GB off heap storage with 4 GB heap sizes this week and next and will revert how that looks. A follow up question - what happens when data does not fit off heap and we have defined affinity, where does it go - on heap or do we start seeing inconsistent results? We do not

Re: java.lang.OutOfMemoryError in normal Ignite usage

Hi, Most probably, you just have insufficient heap, as queries require some heap space during execution. Probably you should give your node more heap and monitor it for some. If all is fine, you will see a saw-like pattern - when memory is allocated and then release. If there is a leak, you will
