-------------------------------------
bq. I'm really not happy where this is going... What would normally take a
single line now requires many object instantiations and I have to manage the
single Cell get all over the place. The patch I attached is not complete and
should be used to see current proposal usage.
Well maybe a way of dealing with it can be hiding scopes and HbaseMapWritable-s
from users as much as possible. Something like:
{code}
Get get = new Get(row);
get.setTimestamp(col1, timestamp1);
get.setTimestamp(col2, timestamp2);
get.setVersions(col2, numVersions);
......
get.setAllTimestamps(timestamp); // for all columns
......
// maybe also add a constructor overload similar to current API
Get get = new Get(row, cols /* array of byte arrays */, timestamp);
{code}
> Improve the current client API by creating new container classes

> The current API does not scale very well. For each new feature, we have to
> add many methods to take care of all the overloads. Also, the need to batch
> row operations (gets, inserts, deletes) implies that we have to manage some
> "entities" like we are able to do with BatchUpdate but not with the other
> operations. The RowLock should be an attribute of such an entity.
> The scope of this jira is only to replace current API with another
> feature-compatible one, other methods will be added in other issues.
