Hi,
We are currently working on a scenario where we have cache with some of the
below configuration.
1. Dedicated data region with min and max provided and eviction enabled
with with Random-2-LRU.
2. External storage persistence for data recovery.
3. two backups
With the above setup we have come across a behavior where if the data from
the cache reaches its limit the data is automatically getting evicted which is
expected. But the issue we are currently facing is that we are not able to
query the data which is evicted using SQL API as the data is not longer present
in **OFF HEAP** memory.
Also when eviction happens can we still retrieve the data from the
configured backups or they will be evicted as well?
In this case the only way to get the data is to explicitly call either of
below methods.
1. cache.get(ID) - This will load specific Key data onto off heap memory
which will then be available for querying
2. cache.loadCache() - In this case do we need to call the method every
time we need to retrieve a specific key from cache data or
for every transaction as the data we are looking for might not be in
cache due to eviction in place?
Can you please suggest any approach where we can perform SQL queries to
retrieve data with Cache eviction in place and don't have to load the data for
every transaction.
Attaching sample configuration for dataregion and cache config
