Method Details

setWALReaderEditsBufferBytes

void setWALReaderEditsBufferBytes(long usage)

Sets the total usage of memory used by edits in memory read from WALs. The memory represented by this usage measure is across peers/sources. For example, we may batch the same WAL edits multiple times for the sake of replicating them to multiple peers..

Parameters:

usage - The memory used by edits in bytes

getWALReaderEditsBufferBytes

long getWALReaderEditsBufferBytes()

Returns the size, in bytes, of edits held in memory to be replicated across all peers.
