Chris Marchbanks	b40cc43958	Provide option to compress WAL records (#609) ... In running Prometheus instances, compressing the records was shown to reduce disk usage by half while incurring a negligible CPU cost. Signed-off-by: Chris Marchbanks <csmarchbanks@gmail.com>	7 years ago
Tom Wilkie	77d5a7d47a	LiveReader can get into an infinite loop on corrupt WALs. (#524) ... Make WAL live tailer return EOF when the there is a half-written record at the end of the file. Previously, this would cause an infinite loop as we ignored EOFs when filling the buffer. We now differentiate between EOFs that read >0 bytes, and EOFs that didn't. Add some more unit tests for tailing a corrupt WAL, and unify interfaces Reader and LiveReader for the purposes of testing. Signed-off-by: Tom Wilkie <tom.wilkie@gmail.com>	7 years ago
