⚠️ This library is in active development: there is currently no release schedule!
lsm-tree is a project that is developed by Well-Typed LLP on behalf of Input Output Global Inc (IOG). The main contributors are Duncan Coutts, Joris Dral, and Oleg Grenrus.
The lsm-tree library is a Haskell implementation of log-structured merge-trees, based on Monkey, that provides an on-disk key-value store.
It has a number of custom features that are primarily tailored towards performant disk IO in the Haskell implementation of the Ouroboros-family of consensus algorithms, which can be found in the ouroboros-consensus repository. Nevertheless, this library should be generally useful for projects that require an on-disk key-value store.
This library only supports 64-bit, little-endian systems.
