> Currently we only have a knob to control maximum number of transactions in the log file
but there is no direct way to control actual size of the file. This has implications on the
time it takes for a learner to sync using transaction log as the leader needs to seek the
file to find the appropriate transaction. This is a proposal for adding a config parameter
to control the transaction log size.
