The vcache-trie package

[ Tags: bsd3, database, library ] [ Propose Tags ]

VCache supports larger-than-memory values with caching, persistence, and structure sharing. Effective use of VCache requires useful data structures be modeled above it. The trie is useful for modeling key value databases or abstract virtual filesystems, where keys have shared prefixes or elements with a common prefix are likely to be updated together.

Currently, the implementation is specialized to a bytestring trie.

Haskell VCache Trie

A Patricia trie implemented above VCache.

Suitable for database-as-a-value or modeling abstract virtual filesystems.

Currently, this only supports bytestring keys, similar to the bytestring-trie package. It may be necessary to later adapt the list-tries model to support arbitrary keys... though, not for any projects I'm pursuing at the moment.
