Adam Warrington updated HBASE-3942:
-----------------------------------
Attachment: HBASE-3942-0.patch
This patch adds a new function called scannerOpenWithScan to the thrift api.
Currently, the thrift api has 5 scannerOpen functions, each supporting
different parameters. Instead of continuing to grow the number of scannerOpen
functions (potentially exponentially) with every new supported parameter, I've
added a new TScan type, which is analogous to the Scan class in the HBase Java
api. This type can grow over time without having to add new scannerOpen
functions with every new supported option.
The TScan type supports 5 options: startRow, stopRow, timestamp, columns, and
caching. This means the new openScannerWithScan function can support all
options the other 5 scannerOpen functions currently support.
> The thrift scannerOpen functions should support row caching

> supported.
