Owen Diehl	4d9865acd4	Adds WAL support (experimental) (#2981) ... * marshalable chunks * wal record types custom serialization * proto types for wal checkpoints * byteswith output unaffected by buffer * wal & record pool ifcs * wal record can hold entries from multiple series * entry pool * ingester uses noopWal * removes duplicate argument passing in ingester code. adds ingester config validation & derives chunk encoding. * segment writing * [WIP] wal recovery from segments * replay uses sync.Maps & preserves WAL fingerprints * in memory wal recovery * wal segment recovery * ingester metrics struct * wal replay locks streamsMtx in instances, adds checkpoint codec * ingester metrics * checkpointer * WAL checkpoint writer * checkpointwriter can write multiple checkpoints * reorgs checkpointing * wires up checkpointwriter to wal * ingester SeriesIter impl * wires up ingesterRecoverer to consume checkpoints * generic recovery fn * generic recovery fn * recover from both wal types * cleans up old tmp checkpoints & allows aborting in flight checkpoints * wires up wal checkpointing * more granular wal logging * fixes off by 1 wal truncation & removes double logging * adds userID to wal records correctly * wire chunk encoding tests * more granular wal metrics * checkpoint encoding test * ignores debug bins * segment replay ignores out of orders * fixes bug between WAL reading []byte validity and proto unmarshalling refs * conf validations, removes comments * flush on shutdown config * POST /ingester/shutdown * renames flush on shutdown * wal & checkpoint use same segment size * writes entries to wal regardless of tailers * makes wal checkpoing duration default to 5m * recovery metrics * encodes headchunks separately for wal purposes * merge upstream * linting * addresses pr feedback uses entry pool in stream push/tailer removes unnecessary pool interaction checkpointbytes comment fillchunk helper, record resetting in tests via pool redundant comment defers wg done in recovery s/num/count/ checkpoint wal uses a logger encodeWithTypeHeader now creates its own []byte removes pool from decodeEntries wal stop can error * prevent shared access bug with tailers and entry pool * removes stream push entry pool optimization	5 years ago
