Subject HerdDB: a Distributed 'embeddable' Database built on Apache BookKeeper
Date Fri, 30 Dec 2016 16:02:33 GMT
Hi all,
I'm glad to announce to all the BookKeepers the first ALPHA release of HerdDB.

HerdDB is a distributed database which:
- is ultra fast for writes
- can be replicated among tens of machines, without any shared medium or SAN
- can handle thousands of tables
- can handle multi-table transactions
- can handle multi-table queries
- scale horizontally on the number of tables, by simply adding macchines
- can optionally run inside the same process of the JVM which runs the
main service
- can be controlled by using SQL language and the JDBC API
- can support indexing of data

It is essentially a Key-Value database with an additional SQL layer
which lets the users make queries using the well known SQL language.

It uses BookKeeper for replication following the common
replicated-state machine pattern.

See this blog post for further details
