Package	Description
com.bigdata.btree	The BTree is a scalable B+-Tree with copy-on-write semantics mapping variable length unsigned byte[] keys to variable length byte[] values (null values are allowed).
com.bigdata.cache	A canonicalizing object cache may be constructed from an outer weak reference value hash map backed by an inner hard reference LRU policy.
com.bigdata.htree
com.bigdata.journal	The journal is an append-only persistence capable data structure supporting atomic commit, named indices, and transactions.
com.bigdata.rdf.lexicon
com.bigdata.resources	This package provides the logic to managed the live journal and the historical journals and index segments for a DataService.
