LevelDB v1.15 Release Notes
Release Date: 2014-09-15 // over 9 years ago-
- ๐ง switched from mmap based writing to simpler stdio based writing. Has a minor impact (0.5 microseconds) on microbenchmarks for asynchronous writes. Synchronous writes speed up from 30ms to 10ms on linux/ext4.
Should be much more reliable on diverse platforms. - compaction errors now immediately put the database into a read-only mode (until it is re-opened). As a downside, a disk going out of space and then space being created will require a re-open to recover from, whereas previously that would happen automatically. On the plus side, many corruption possibilities go away.
- ๐ force the DB to enter an error-state so that all future writes fail when a synchronous log write succeeds but the sync fails.
- repair now regenerates sstables that exhibit problems
- ๐ fix issue #224 - Use native memory barriers on OSX
- ๐ fix issue #218 - QNX build is broken
- ๐ fix build on iOS with xcode 5
- ๐ make tests compile and pass on windows
