Using HBase Thrift API to move a number of rows

Hi

Is there a way to use the HBase Thrift Scanner to just jump a number of
rows instead of reading them one by one. This is very useful for paging.

Thanks a lot Nick

I implemented it that way and it works perfectly.

I believe so, yes. Your client would take note of the last row key returned
and use that to decide on the new start row key.

Hi Nick

So what do I use to seek from row 10? The start row?

Same as in Java clients, you use the PageFilter to limit result ranges.
