RHDG 7 FileStorage preloading Order

Solution Unverified - Updated -

Issue

  • What is the FileStorage preload filling order when warming up the cache?
  • When using the preload in memory with a fixed number of records (e.g 6.000.000). How does datagrid select the 6.000.000 of records that are preloaded in memory amongst the limit ? Is it random or there is a given order?

Environment

  • Red Hat Data Grid (RHDG)
    • 7.x
  • Infinispan cache configured with both eviction and preload:
<!-- eviction -->
            <memory>
                <object size="6000000"/>
            </memory>
<!-- persistence with pre-load=true -->            
<persistence passivation="false">
                <file-store fetch-state="true" purge="false" read-only="false" preload="true" shared="false" path="/jboss/app/udm_core/data/CacheStore">

                </file-store>
            </persistence>
