A scalable concurrent {@link ConcurrentNavigableMap} implementation. The map is sorted according to the {@linkplain Comparable natural ordering} of its keys, or by a {@link Comparator} provided at map creation time.

Concurrency aware, can verify that its configuration is thread safe

A database with easy access to named maps and other collections.

Exception hierarchy for MapDB

Concurrent HashMap which uses IndexTree for hash table

ArrayList like structure backed by tree

Primitive Sorted Map<Long,Long.

Extra methods for Map interface

Data streaming

FIFO Queue with option to remove element from middle

Wraps volume factory and returns volume as readonly

Uses Elsa serialization: http://www.github.com/jankotek/elsa

Read only Sorted Table Map. It stores data in table and uses binary search to find records

Stores records, mutable version

Store which uses binary storage (file, memory buffer...) and updates records on place. It has memory allocator, so it reuses space freed by deletes and updates.

Common utils for StoreDirect, StoreWAL and StoreCached

Stores records

Store which does not use serialization, but puts everything into on-heap Map.

Wraps Store and throws UnsupportedOperationException("Read-only") on operations which would modify it

Store which serializes its content into primitive Map<Long,byte[]>. It optionally persist its content into file, in this case it supports rollback and durability.

Stores records, transactional version

StoreDirect with write ahead log

Class can verify its status and data integrity: collections, Stores...
