## master / unreleased
|
|
- [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.
|
|
- [REMOVED] `PrefixMatcher` is considered unused so was removed.
|
|
- [CLEANUP] `Options.WALFlushInterval` is removed as it wasn't used anywhere.

|
|
- [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.
