In running Prometheus instances, compressing the records was shown to
reduce disk usage by half while incurring a negligible CPU cost.

Test createBlock and check all os.RemoveAll in the tests for errors. (#549)
Testing that createBlock creates blocks that can be opened.

and checking the os.RemoveAll for errors will catch errors for un-closed files under windows.

Many missing .Close() calls were added for fixing failing os.RemoveAll

Fabian Reinartz 1e88ba06b4 Use boolean function instead of postings to drop WAL series
There is not guarantee or requirement for WAL writers to only add
series entries in increasing order of IDs. A postings list cannot look
back and thus unordered WAL entries would skip over IDs to not truncate
from the WAL.
We replace it with a simple boolean check function that does not require
order.

Fabian Reinartz 6892fc6dcb Finish old WAL segment async, default to no fsync
We were still fsyncing while holding the write lock when we cut a new
segment. Given we cannot do anything but logging errors, we might just
as well complete segments asynchronously.

There's not realistic use case where one would fsync after every WAL
entry, thus make the default of a flush interval of 0 to never fsync
which is a much more likely use case.
