AI Analysis

●●SolidWizardryShip It

LSM-tree with SSI, column families, and adaptive compaction—solid database primitives, nothing novel.

Strengths

•Five-tier isolation levels with Serializable Snapshot Isolation and write-skew detection prevents all known anomalies.
•Hybrid compaction modes (full merge, dividing, partitioned) with dynamic capacity adjustment minimize write/space amplification tradeoffs.
•Lock-free block manager using atomic operations + two-tier caching; real systems engineering rigor.

Weaknesses

•Not a full database—users must build storage layer on top, limiting immediate applicability.
•No published benchmarks against RocksDB, LevelDB, or SQLite; difficult to assess real-world performance claims.

Post Description

Hey everyone! sharing an open source storage engine I created and work on called TidesDB. I hope you check it out, and do let me know your thoughts and or questions!

You can also find design documentation, benchmarks, libraries and more on the website.
