Release date: not yet released
- Add support for the Thrift compact protocol (TCompactProtocol) in Connection.
Release date: 2014-02-25
- Add (and default to) ‘0.96’ compatibility mode in Connection.
- Add support for retrieving sorted columns, which is possible with the HBase 0.96 Thrift API. This feature uses a new sorted_columns argument to Table.scan(). An `OrderedDict implementation is required for this feature; with Python 2.7 this is available from the standard library, but for Python 2.6 a separate `ordereddict` pacakge has to be installed from PyPI. (issue #39)
- The batch_size argument to Table.scan() is no longer propagated to Scan.setBatching() at the Java side (inside the Thrift server). To influence the Scan.setBatching() (which may split rows into partial rows) a new scan_batching argument to Table.scan() has been added. See issue #54, issue #56, and the HBase docs for Scan.setBatching() for more details.
Release date: 2013-11-06
- Added a wal argument to various data manipulation methods on the Table and Batch classes to determine whether to write the mutation to the Write-Ahead Log (WAL). (issue #36)
- Pass batch_size to underlying Thrift Scan instance (issue #38).
- Expose server name and port in Table.regions() (recent HBase versions only) (issue #37).
- Regenerated bundled Thrift API modules using a recent upstream Thrift API definition. This is required to expose newly added API.

- Added a thread-safe connection pool (ConnectionPool) to keep connections open and share them between threads (issue #21).
- The Connection.delete_table() method now features an optional disable parameter to make deleting enabled tables easier.
- The debug log message emitted by Table.scan() when closing a scanner now includes both the number of rows returned to the calling code, and also the number of rows actually fetched from the server. If scanners are not completely iterated over (e.g. because of a ‘break’ statement in the for loop for the scanner), these numbers may differ. If this happens often, and the differences are big, this may be a hint that the batch_size parameter to Table.scan() is not optimal for your application.
- Increased Thrift dependency to at least 0.8. Older versions are no longer available from PyPI. HappyBase should not be used with obsoleted Thrift versions.
- The Connection constructor now features an optional timeout parameter to to specify the timeout to use for the Thrift socket (issue #15)
- The timestamp argument to various methods now also accepts long values in addition to int values. This fixes problems with large timestamp values on 32-bit systems. (issue #23).
- In some corner cases exceptions were raised during interpreter shutdown while closing any remaining open connections. (issue #18)
Release date: 2012-07-11
- Add an optional table_prefix_separator argument to the Connection constructor, to specify the prefix used for the table_prefix argument (issue #3)
- Add support for framed Thrift transports using a new optional transport argument to Connection (issue #6)
- Add the Apache license conditions in the license statement (for the included HBase parts)
- Documentation improvements
Release date: 2012-05-25
- Improved compatibility with HBase 0.90.x
- In earlier versions, using Table.scan() in combination with HBase 0.90.x often resulted in crashes, caused by incompatibilities in the underlying Thrift protocol.
- A new compat flag to the Connection constructor has been added to enable compatibility with HBase 0.90.x.
- Note that the Table.scan() API has a few limitations when used with HBase 0.90.x.
- The row_prefix argument to Table.scan() can now be used together with filter and timestamp arguments.
- Lower Thrift dependency to 0.6
- The setup.py script no longer installs the tests
- Documentation improvements
Release date: 2012-05-22
- Fix package installation, so that pip install happybase works as expected (issue #1)
- Various small documentation improvements
Release date: 2012-05-20
