partial key scan
Hi,
The HBase book "The definitive guide" describes the concept of partial key
scans, I'd like to use that to find a user's groups where the key is made
up of userid - groupid so I just need to scan for userid and I'll get all
of the groups for that user. Thrift doesn't appear to support this unless
I'm missing something. I believe I'm using the latest release of Thrift in
0.7.0.
Cheers

It is almost definitely a bug in either the server-side code that
implement the operation, or in the documentation for it, or your
understanding of it. :)
Think of it this way: all thrift does is get data from here to there. How
it's generated is someone else's issue.

Greg, this is the mailing list for the Apache Thrift *framework*, not the
HBase Thrift gateway. The latter is just a part of the HBase project.

Jake,
To be honest I really think this is a thrift issue. Both of the following
two methods return the same thing, the second sounds like it should be
matching the prefix of a key which is exactly what I'm after.
scannerOpen(table, row, columns) and
scannerOpenWithPrefix(table, prefix, columns)
Cheers

Greg
If the thrift idl for HBase defines a service to do this then it would be possible. This would be a better question for the HBase user group
