Specifies memory in units of bytes. Use the suffix k or m to specify units of kilobytes or megabytes, respectively. The default
is 1m.
When more than one -n option or -s option is specified in the command line, dbmlsync may experience fragmentation which results
in discarded memory. The discarded memory can only be recovered by rescanning the database transaction log. This option lets
you specify a limit on the amount of discarded memory that is allowed to accumulate before the log is rescanned and the memory
recovered. Another way to control the recovery of discarded memory is to implement the sp_hook_dbmlsync_log_rescan stored
procedure.
