Couchbase Buckets: provide data persistence and data replication. Data stored in Couchbase Buckets is highly-available and reconfigurable without server downtime. They can survive node failures and restore data plus allow cluster reconfiguration while still fulfilling service requests.
The main features are:
- Supports items up to 20MB in size.
- Persistence, including data sets that are larger than the allocated memory size for a bucket. You can configure persistence per bucket and Couchbase Server will persist data asynchronously from RAM to disk.
- Fully supports replication and server rebalancing. You can configure one or more replica servers for a Couchbase bucket. If a node fails, a replica node can be promoted to be the host node.
- Full range of statistics supported.
