Summary: Implement batch processing of Raft log entries
Key: IGNITE-19946
URL: https://issues.apache.org/jira/browse/IGNITE-19946
Project: Ignite
Issue Type: Improvement
Reporter: Ivan Bessonov
Issue is created as a part of IGNITE-15568. Here we need to implement batches
for the log specifically, so that there will be less IO while writing data into
a shared log storage.
Copy of the comment in that issue:
_The actual implementation here differs from the description._
_First of all, only the log manager is affected._
_Second, instead of having a single event that would notify all listeners, I
re-use the "endOfBatch" flag. This solution is not as general, and it can be
later re-implemented using additional event, but I decided not to change the
API too much for now._
_Log manager internally has the information about the stripe it belongs to.
Using that information, it's possible to perform a single write into a shared
log storage, even when batch consists of data from several different
replication groups._
