description: Figaro High Availability, or HA, adds support for replicated systems to Figaro Transactional Data Store (TDS). There are two basic reasons to build a replicated highly available system: scale and reliability.
    - Scale your transactional application beyond the processing constraints of a single system.
    - Deliver a highly reliable system where the failure of one node does not cause system-wide failure.

Replicated databases come in some different configurations. The HA layer of the Oracle Berkeley DB database engine can be configured for any of the replicated designs that involve a single writer as a master and multiple replicas allowing for read-only access to data.

Figaro HA supports the entire range of configurations from a simple hot standby with failover setup to a geographically diverse set of tiered replica clusters. Figaro HA makes no assumptions about how the nodes communicate with one another; it will support TCP/IP communications networks.

Figaro HA supports any topology regardless of the number of replicated nodes within it. Upon notification of a failure of the master node, an election algorithm will identify a new master so that processing can continue uninterrupted. Figaro HA can even be used as a completely diskless in memory reliable distributed storage system.

Choose Figaro HA when:
    - Single-system throughput isn&#39;t enough to meet your data requirements.
    - System uptime of %99.999 or better is a requirement.
    - The system must be able to survive node failure.
    - There is a need for consistent online backup of system data.
    - Your architecture calls for a hot-failover strategy.
    - Your hardware device has multiple redundant systems and must be able to fail from one to the other gracefully.
