+ CheckpointStats.repl_map_cutoff_lsn = cutoff;
Could we set repl_map_cutoff_lsn closer to where it is calculated? Right
now, it's set at the bottom of the function just before the directory is
freed. Is there a strong reason to do it there?
+ "logical rewrite mapping file(s) removed/synced=" UINT64_FORMAT ", size=%zu bytes, time=%ld.%03d s, cutoff LSN=%X/%X",
Can we split out the "removed" versus "synced" files? Otherwise, I think
this is basically just telling us how many files are in the mappings
directory.
+ CheckpointStats.repl_snap_cutoff_lsn = cutoff;
I have the same note for this one as I have for repl_map_cutoff_lsn.
