Vermeer is a self-clustering database server for doing atomic distributed transactions and uses Biglog as its store. There are no masters or slaves, leaders or elections, or transaction coordinators: just a consensus of parts. Adding to the cluster is as simple as bringing up new instances.
Vermeer offers cell-level ACLs, secondary indexes, schemas and more. Vermeer partitions at the level of logical streams which are easily definable, and transactions can occur across multiple objects and streams. An HTTP API is built-in.
Vermeer extends the Linda data coordination language, so fully supports publish-subscribe semantics intuitively.
Biglog is a log-structured storage system with an in-memory index. It is designed to be safe, reliable and fast. With transactions, unlimited multi-values (ie. queues), sparse/wide columns, column-families, streaming, BLOBs, and regex searches on keys/columns and secondary indexes. Bigdog is a wrapper for managing multiple Biglog instances, for example transactions over multiple data sets or replicas/mirrors.
