Data-Center Replication

+

In previous releases, Accumulo only operated withing the constraints of a single installation. +Because single instances of Accumulo often consist of many nodes and Accumulo's design scales +efficiently across many nodes, it is typical that one Accumulo is run per physical installation +or data-center. ACCUMULO-378 introduces support in Accumulo to automatically +copy data from one Accumulo instance to another.

+

This data-center replication feature is directly applicable for users wishing to implement +a disaster recovery strategy. Data can be automatically sent from a primary instance to one +or more other Accumulo instances. Conversely to normal Accumulo operation in which ingest and +query are strongly consistent, replication is a lazy, eventually consistent operation. This +is desirable for replication as it prevent additional latency for ingest operations on the +primary instance. Additionally, outages between the primary instance and replicas can sustain +prolonged outages without any administrative overhead.

+

The Accumulo User Manual contains a new chapter on replication which covers +in better detail the design and implementation of the feature, how users can configure replication +and special cases to consider when choosing to integrate the feature into a user application.

User Initiated Compaction Strategies

Per table compaction strategies were added in 1.6.0. In 1.7.0 the ability to specify a compaction strategy for a user initiated compaction was added in
