---

Release 1.2.0 (Rashomon)

Released on 2012-11-09.

Changes

This is the first release of the product. It includes:

• JSON data model and immediate consistency support
• Distributed joins, subqueries, aggregation, atomic updates
• Hadoop-style map/reduce
• Friendly web and command-line administration tools
• Takes care of machine failures and network interrupts
• Multi-datacenter replication and failover
• Sharding and replication to multiple nodes
• Queries are automatically parallelized and distributed
• Lock-free operation via MVCC concurrency

Limitations

There are a number of technical limitations that aren't baked into the architecture, but were not resolved in this release due to time pressure. They will be resolved in subsequent releases.

• Write requests have minimal batching in memory and are flushed to disk on every write. This significantly limits write performance, expecially on rotational disks.
• Range commands currently don't use an index.
• The clustering system has a bottleneck in cluster metadata propagation. Cluster management slows down significantly when more than sixteen shards are used.
