Memory utilization of Indexes in ignite

[Tejashwa Kumar Verma <te...@gmail.com>]

Hi All,

I have some open questions about memory utilization of indexes in ignite.

So here is the scenario.
I have created one cache(CACHE_1) with following props:
<property name="offHeapMaxMemory" value="#{1 * 1024L * 1024L * 1024L}" />
<property name="cacheMode" value="PARTITIONED" />
<property name="swapEnabled" value="true" />

And i am loading 5GB in CACHE_1. So as per our configs 1 GB data is
residing in offHeap and remaining 4GB is going in swap.

Now my question is where exactly indexes are going in offHeap or Swap?




Thanks & Regards
Tejas

Hi Tejas,

Ignite will store indexes in off-heap, but indexes can't be swapped to a
disk.

However in the latest version of ignite, disk storage was implemented and
indexes can be saved on the disk, but it's unlikely because indexes are hot
data that should be kept in memory.


Thanks,
Mike.
