lcdb - a reimplementation of LevelDB in C89

DISCLAIMER: lcdb has no affiliation with or endorsement from Google Inc. whatsoever despite the API prefix being ldb_ (let's hope they don't cease and desist us again).

A state-of-the-art database in C89 (originally designed by Jeffrey Dean and Sanjay Ghemawat and implemented in C++).


Why?

LevelDB was painstakingly ported from C++ to C89¹ for use with mako. mako is a C project which requires an LSM tree for its UTXO database (which in turn requires high write throughput with very effective compaction). mako has a strict development policy of "do not link to libstdc++" and "do not require a c++ compiler".
