When will setFetchSize() work properly ?

[R Lenard]

According to the javadoc/source (with 3.0.16) it appears that the driver only support

1 row at a time (streamed) or all rows in a go.

Now 1 row at a time is *REALLY* poor for performance with large data sets (but allows you to ensure you will always have sufficient memory to hit the data), but all rows in a go requires the a-priori knowledge of how many rows will be pulled over to ensure there is sufficient memory on the client to hold the results (which is a bit chicken before the egg).

When will setFetchSize() allow setting of values, so that setFetchSize(100) limits the number fetched to 100 at a time, but still allows all the data to be retreived (i.e. in chunks of 100) ?
