> Implement Aerospike Datastore
> -----------------------------
>
> Key: GORA-502
> URL: https://issues.apache.org/jira/browse/GORA-502
> Project: Apache Gora
> Issue Type: New Feature
> Components: gora-aerospike, storage
> Affects Versions: 0.6.1
> Reporter: Cihad Guzel
> Assignee: Nishadi Kirielle
> Labels: gsoc2017
> Fix For: 0.8
>
>
> Aerospike is a NoSQL database solution for real-time operational
> applications, delivering predictable performance at scale, superior uptime,
> and high availability at the lowest TCO compared to first-generation NoSQL
> and relational databases. It could be nice to support Aerospike as a
> datastore at Gora. Aerospike uses Apache v2 license for Java client and uses
> aGPL license for Aerospike Server Community Edition.
