Hi Anand,
Ignite will collect a batch of updates for multiple operations if you enable
write-behind.
So, it will be done for entry.setvalue() within Cache.invoke for your case.
And then Ignite will make a writeall() call for the batch.
If your own CacheStore implementation does not override writeall() method
then a default implementation will be used:
foreach (entry in a batch) {
write(entry);
}
So, please implement writeall() with respect to your legacy DB to have a
performance boost for batch updates.
Thank you,
Alexey
