[jira] [Created] (HBASE-3942) The thrift scannerOpen functions
should support row caching
The thrift scannerOpen functions should support row caching
-----------------------------------------------------------
Key: HBASE-3942
URL: https://issues.apache.org/jira/browse/HBASE-3942
Project: HBase
Issue Type: Improvement
Components: thrift
Affects Versions: 0.90.3
Reporter: Adam Warrington
After noticing very poor scanner performance using the Thrift api, I realized that there was no way to set caching on the scanner. This should probably be supported.

[jira] [Updated] (HBASE-3942) The thrift scannerOpen functions
should support row caching
Posted by "Adam Warrington (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HBASE-3942?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
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.
