With this patch, Data and Meta GFIDs are post processed. If Changelog has
UNLINK entry then remove from Data and Meta GFIDs list(If stat on GFID is
ENOENT in Master).
While processing Changelogs,
- Collect all the data and meta operations in a temporary database
- Delete all Data and Meta GFIDs which are already unlinked as per Changelogs
(unlink only if stat on GFID is ENOENT)
- Process all Entry operations as usual
- Process data and meta operations in batch(Fetch from Db in batch)
- Data sync is again batched based on number of changelogs(Default 1day
changelogs). Once the sync is complete, Update last Changelog's time as last_synced
time as usual.
Additionally maintain entry_stime on Brick root, ignore Entry ops if changelog
suffix time is less than entry_stime. If data stime is more than entry_stime,
this can happen only when passive worker updates stime by itself by getting
mount point stime. Use entry_stime = data_stime in this case.
New configurations:
max-rsync-retries - Default Value is 10
max-data-changelogs-in-batch - Max number of changelogs to be considered in a
batch for syncing. Default value is 5760(4 changelogs per min * 60 min *
24 hours)
max-history-changelogs-in-batch - Max number of history changelogs to be
processed at once. Default value 86400(4 changelogs per min * 60 min * 24
hours * 15 days)
