Aerospike 3 by Alex Popescu.
From the post:
Aerospike 3 database builds off of Aerospike’s legacy of speed, scale, and reliability, adding an extensible data model that supports complex data types, large data types, queries using secondary indexes, user defined functions (UDFs) and distributed aggregations. Process more data faster to create the richest, most relevant real-time interactions.
Aerospike 3 Community Edition is a free unlimited license designed for a single cluster of up to two nodes and storage of up to 200GB of data. Enterprise version is available upon request.
Alex has picked up a new sponsor that merits your attention!
From the community download page:
Free Aerospike 3 Community Edition is a full copy of Aerospike Database, in a 2-node cluster configuration that supports a database up to 200 GB in size. For example, if you have 125 million records at 1.5 K bytes/object, you can do 16k reads/sec and 8k/writes/sec with data on SSD. Or, if you are deploying an in-memory database, you can handle 60k reads/sec and 30k writes/sec. This product includes:
- Unlimited license to use the software forever. No fees, no strings attached.
- Access to online forums and documentation
- Tools for setting up and managing two Aerospike Servers in a single Aerospike Cluster
- Aerospike Server software and Aerospike SDK for developing your database client application
- When scale demands, easy upgrade to the Enterprise Edition without stopping your service!
The in-memory performance numbers look particularly impressive!
