Eric Evans commented on CASSANDRA-926:
--------------------------------------
* 0001: adds record defs to {{internode.genavro}} that had been previously
"included" from cassandra.genavro. Since the records where added to the
{{org.apache.cassandra.db.migration.avro}} package, this patch also contains a
lot of search-and-replace to update it from {{org.apache.cassandra.avro}}.
* 0002: strips {{cassandra.genavro}} over everything not needed by the hadoop
package.
* 0003: removes the option to start an avro daemon from {{bin/cassandra}}
* 0004: removes the functional tests.
* 0005: removes (non-generated )source for the rpc interface.
* 0006: moves the remaining records to the hadoop package.
> implement alternative RPC interface using Avro

> *UPDATE: This ticket is now for the removal of the Avro interface, (see
> http://thread.gmane.org/gmane.comp.db.cassandra.client.devel/36 for
> background).*
> Avro is data serialization and RPC framework similar to Thrift. It provides:
> * Rich data structures.
> * A compact, fast, binary data format.
> * A container file, to store persistent data.
> * Remote procedure call (RPC).
> * Simple integration with dynamic languages. Code generation is not required
> to read or write data files nor to use or implement RPC protocols. Code
> generation as an optional optimization, only worth implementing for
> statically typed languages.
> Cassandra's Avro interface is being structured in a way that closely mirrors
> the existing Thrift interface, both in terms of public facing API, and how it
> is implemented. GSOC students interested in this task should begin by
> familiarizing themselves with Cassandra's Thrift service
> (org.apache.cassandra.thrift).
> Note: This is a very large and long-running task so treat this as a
> meta-issue and add sub-tasks and/or blocking issues as appropriate.
