Veena Basavaraj commented on SQOOP-1557:
----------------------------------------
Recent changes have moved the SQ_DIRECTION out of config and added a Config
Directions table. Hence this patch only contains the SQ_CONFIGURABLE changes
and related code to make Driver a first class citizen in the repo. It now has a
real persistence ID, instead of a fake ID.

> SQ_CONNECTOR -> will be now call SQ_CONFIGURABLE ( it is basically a table to
> hold entities that will specify configs)
> Add another field to it, that is CONFIGURABLE_TYPE ( it can be connector or
> driver at this point ). we can have a standard id for Driver that we will
> use in the SQOOP, having nulls to represent things is not clean since
> "none/null" can mean different things at different contexts
> Most importantly, not to have NULLs representing one too many things!!
>
> Next,
> We propose to split up the SQ_FORM ( which is the SQ_CONFIG after 1498) to
> SQ_JOB_CONFIG and SQ_LINK_CONFIG ( it will parallel the SQ_JOB_INPUT and
> SQ_LINK_INPUT)
> Direction is only relevant to job config ( and henceforth the job inputs). So
> we will store the DIRECTION field in JOB_CONFIG.
> If we want to have SQ_CONFIG, we can have it with the SQ_CFG_TYPE and then it
> will have FK on the SQ_CONFIGURABLE, so we know which entity owns this
> config easily.
> We can then have SQ_JOB_CONFIG and SQ_LINK_CONFIG have a FK on SQ_CONFIG.
> Alternatively, dont have SQ_CONFIG, and just have SQ_JOB_CONFIG and
> SQ_LINK_CONFIG and have a FK directly to SQ_CONFIGURABLE, both will have the
> CONFIG_NAME and INDEX fields.
