Some checks failed
Go Tests / Run Tests (1.24.2) (push) Has been cancelled
Adds a complete LSM-based storage engine with these features: - Single-writer based architecture for the storage engine - WAL for durability, and hey it's configurable - MemTable with skip list implementation for fast read/writes - SSTable with block-based structure for on-disk level-based storage - Background compaction with tiered strategy - ACID transactions - Good documentation (I hope)
