> Currently, incremental backup is based on WAL files. Bulk data loading bypasses WALs
for obvious reasons, breaking incremental backups. The only way to continue backups after
bulk loading is to create new full backup of a table. This may not be feasible for customers
who do bulk loading regularly (say, every day).
> Here is the review board (out of date):
> https://reviews.apache.org/r/54258/
> In order not to miss the hfiles which are loaded into region directories in a situation
where postBulkLoadHFile() hook is not called (bulk load being interrupted), we record hfile
names thru preCommitStoreFile() hook.
> At time of incremental backup, we check the presence of such hfiles. If they are present,
they become part of the incremental backup image.
