jsteemann 81229b8f39 Added sequence number hint for GetSortedWalFiles
Added an optional SequenceNumber hint to WAL manager's GetSortedWalFiles
API. This allows GetSortedWalFiles to prune irrelevant files early. It
will use the sequence number cache for this. This requires a scan over
the sequence number cache, which will take time proportional to the
number of entries in the cache. However, it may still be a lot better
than peeking into the WAL files and performing lots of IO.
The change helps when there are many (archived) WAL files and the first
call to GetUpdatesSince() with a sequence number close to the tip of the
WAL. Previously, this would open _all_ available WAL files and read
their first entries to find out the lowest sequence number per file.
With the change, we now keep track of the lowest sequence number as we
open files, so that we can ignore all WAL files with a log number that
is lower than the log number we will need.
Note that the sequence number given to GetSortedWalFiles is only a hint,
which is used as a performance optimization.
The API can still return more files than needed, so that callers may
still want to post-filter its result (GetUpdatesSince does so). But in
the ideal case the hint allows performing less file IOs or at least
building up smaller in-memory results.
