HappyBase 0.5¶

Release date: 2013-05-24

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

New features:

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.
