SQLite4: SQLite4
This Is Probably Not The Project You Are Looking For SQLite4 was an experimental rewrite of SQLite that was active from 2012 through 2014. All development work on SQLite4 has ended. Lessons learned from SQLite4 have been folded into the main SQLite3 product. SQLite4 was never released. There are no plans to revive it. You should be using SQLite3. This repository preserves the history of the SQLite

1. Summary SQLite reads and writes small bl obs (for example, thumbnail images) 35% fasterÂ¹ than the same bl obs can be read from or written to individual files on disk using fread() or fwrite(). Furthermore, a single SQLite database holding 10-kilobyte bl obs uses about 20% less disk space than storing the bl obs in individual files. The performance difference arises (we believe) because when working

LMDB | symas
An ultra-fast, ultra-compact, crash-proof, key-value, embedded data store Symas LMDB is an extraordinarilyÂ fast, memory-efficient database we developed for theÂ OpenLDAP Project.Â With memory-mapped files, LMDB has the read performance of a pure in-memory database while retaining the persistence of standard disk-based databases. Bottom line, with only 32KB of object code, LMDB may seem tiny. But itâ€™
