Benchmark Changes (mainline v0.0.2 -> v0.0.3)
- added new
mergemodule withMergeIteratorfor efficient merging of multiple iterators - implemented
Peekableadapter inpeek.rsto allow peeking at next item without consuming - updated
Memtableto usePeekableiterator - optimized
MergeIteratorto handle pointer entries and exhausted iterators - added comprehensive tests for
MergeIteratorandPeekable - improved performance of key lookups in memtables
- refactored
KeyBytesandValueBytesserialization/deserialization - added benchmarks for database operations in
benches/db.rs - implemented new merge benchmarks in
benches/merge.rs - updated
README.mdwith info on MVCC semantics and hybrid logical clock - added
sysinfo.pyscript to gather system information for benchmarks - various minor code cleanups and optimizations throughout
Results
to read the benchmark groups, the structure is like this:
