Cassandra vs. Oracle vs. Couchbase

Stitch is a wrapper around a Cassandra database. It has a web application that provides read-access to the counts through an HTTP API. The counts are written to Cassandra in two distinct ways, and it's possible to use either or both of them:

• Real-time: For real-time updates, Stitch has a processor application that handles a stream of events coming from a broker and increments the appropriate counts in Cassandra.

• Batch: The batch part is a MapReduce job running on Hadoop that reads event logs, calculates the overall totals, and bulk loads this into Cassandra.

Implements the App Engine Datastore API.

Stores massive data, distributed among many different clusters.

Cassandra is our data management workhorse. It handles all our key-value services, supports time-series data storage and retrieval, securely stores all our audit trails, and backs our Datomic database.

Logs storage and aggregation

We are using Cassandra in a few of our apps. One of them is as a count service application to track the number of shares, clicks.. etc

Storage and management of Virtual Services

While we experimented with Cassandra in the past, we are no longer using it. It is, however, open for consideration in future projects.

Main data storage. Any writes to Couchbase auto-replicate to Elasticsearch (via XDRC) and from there on propagate into the internal Jezebel pipeline via opes.

We use Couchbase heavily in our PowerStandings platform to enable real-time analytics of agent data, as well as data storage for parts of our new Playbooks product.
