Is the following statement true in all cases for REPLICATED mode ?

[userx <ga...@gmail.com>]

Hi team,

I was going through the documentation of REPLICATED cache at
https://apacheignite.readme.io/docs/cache-modes#replicated-mode

and came across the following statement.

"As the same data is stored on all cluster nodes, the size of a replicated
cache is limited by the amount of memory available on the node with the
smallest amount of RAM."

I am not sure if this statement is correct in case of a configuration with
Persistent Store enabled. Is the understanding correct ?

Andrey, this is not how Ignite persistence works.

When the persistence is enabled, all the data will be persisted, without
exceptions. If the data size exceeds the the pre-configured allocated
memory, then Ignite will start purging the cold pages and will only keep
the hot data in memory.

Hi,

When persistence store is enabled the data pages that can't be stored in the
memory will be evicted to the persistence store. But capacity of your disks
is still limit your data set size. So the statement is still correct.
