Brian O'Neill commented on CASSANDRA-13475:
-------------------------------------------
A "storage engine" is analogous to the storage engine concept of MySQL. InnoDB
and MyISAM are MySQL storage engines, and a few others exist as well. A driver
swap is analogous to swapping MySQL for PostgreSQL, which aren't fully
compatible. Pluggable storage inside Cassandra allows applications to continue
using Cassandra, and with a high degree of compatibility.
An application can define tables against the engine which make the most sense,
and all of them can co-exist. Over time, the preferred storage engine might
change, much like how InnoDB is preferred over MyISAM, which was the original.

> In this jira, we discuss how to make Cassandra's storage engine to be
> pluggable. We will discuss the scope, expectation, and guideline for this
> project, as well as a detailed design so that we can create sub tasks for
> each small project.
> Here is a design doc we are currently working on:
