Subject [jira] [Commented] (ACCUMULO-2589) Create new client API
Date Wed, 03 Dec 2014 17:47:13 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-2589?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14233236#comment-14233236
] 

Christopher Tubbs commented on ACCUMULO-2589:
---------------------------------------------

For serialization... I mostly meant things we currently use "Writable" for... like Key and
Value and Credentials and Authorizations. Not thrift serialization, but things we either manually
serialize to a byte array / byte buffer to pass to thrift, or things we serialize for non-thrift
persistence.

I'll start isolating changes and incrementally bringing stuff into a branch after my next
rebase.

> There are many issues with the current client API, and we've had a lot of lessons learned
that could be incorporated into a new one.
> Some of the issues this would address:
> * questions like "What is considered 'Public API'?"
> * automated testing for incompatible API changes
> * provide better support for alternative implementations of pluggable features
> * distinguish between compile-time dependencies and runtime dependencies
> * consistent exception handling
> * consistent/symmetric getters/setters
> * well-defined resource lifecycles
> * better resource management
> * simpler entry point to communicate with Accumulo
> * better support for client-side configuration management
> * logical layout of first class Accumulo objects in the API (Table, User, Scan, Connection)
> Some of these goal may evolve during the development of this feature, and many previously
identified issues can be moved to sub-tasks of this one. This ticket is intended to cover
the overall feature, but the details will be handled in sub-tasks.
