- [ENHANCEMENT] Time-ovelapping blocks are now allowed. [#370 ](https://github.com/prometheus/tsdb/pull/370 )
- Added `MergeChunks` function in `chunkenc/xor.go` to merge 2 time-overlapping chunks.
- Added `MergeOverlappingChunks` function in `chunks/chunks.go` to merge multiple time-overlapping Chunk Metas.
- Added `MinTime` and `MaxTime` method for `BlockReader` .

- [CHANGE] `NewLeveledCompactor` takes a context so that a compaction is canceled when closing the db.

- [ENHANCEMENT] When closing the db any running compaction will be cancelled so it doesn't block.
2019-01-23 13:46:58 +00:00
- [CHANGE] `prometheus_tsdb_storage_blocks_bytes_total` is now `prometheus_tsdb_storage_blocks_bytes`

## 0.4.0
2018-12-18 18:56:51 +00:00
- [CHANGE] New `WALSegmentSize` option to override the `DefaultOptions.WALSegmentSize` . Added to allow using smaller wal files. For example using tmpfs on a RPI to minimise the SD card wear out from the constant WAL writes. As part of this change the `DefaultOptions.WALSegmentSize` constant was also exposed.
2019-01-18 08:35:16 +00:00
- [CHANGE] Empty blocks are not written during compaction [#374 ](https://github.com/prometheus/tsdb/pull/374 )
2019-01-16 10:03:52 +00:00
- [FEATURE] Size base retention through `Options.MaxBytes` . As part of this change:
2019-02-14 13:29:41 +00:00
- Added new metrics - `prometheus_tsdb_storage_blocks_bytes_total` , `prometheus_tsdb_size_retentions_total` , `prometheus_tsdb_time_retentions_total`
- New public interface `SizeReader: Size() int64`
- `OpenBlock` signature changed to take a logger.
2018-12-28 18:13:02 +00:00
- [REMOVED] `PrefixMatcher` is considered unused so was removed.
2018-12-28 17:42:46 +00:00
- [CLEANUP] `Options.WALFlushInterval` is removed as it wasn't used anywhere.
2019-01-16 18:09:08 +00:00
- [FEATURE] Add new `LiveReader` to WAL pacakge. Added to allow live tailing of a WAL segment, used by Prometheus Remote Write after refactor. The main difference between the new reader and the existing `Reader` is that for `LiveReader` a call to `Next()` that returns false does not mean that there will never be more data to read.

## 0.3.1
2018-12-28 17:42:46 +00:00
- [BUGFIX] Fixed most windows test and some actual bugs for unclosed file readers.
2018-12-04 13:50:11 +00:00
## 0.3.0
- [CHANGE] `LastCheckpoint()` used to return just the segment name and now it returns the full relative path.
- [CHANGE] `NewSegmentsRangeReader()` can now read over miltiple wal ranges by using the new `SegmentRange{}` struct.
- [CHANGE] `CorruptionErr{}` now also exposes the Segment `Dir` which is added when displaying any errors.
- [CHANGE] `Head.Init()` is changed to `Head.Init(minValidTime int64)`
- [CHANGE] `SymbolTable()` renamed to `SymbolTableSize()` to make the name consistent with the `Block{ symbolTableSize uint64 }` field.
- [CHANGE] `wal.Reader{}` now exposes `Segment()` for the current segment being read and `Offset()` for the current offset.

- [FEATURE] tsdbutil analyze subcomand to find churn, high cardinality, etc.
