Hello, Now that Hypertable version 0.9.8.0 is out the door, I'd like to point out some significant changes that have gone into the release. These changes are described below.
*1. *Default port numbers have changed from 380XX to 1586X. The reason for this is that on some Linux systems, the ephemeral port range goes from 32768-65535 which was causing startup problems due to port conflicts. *2. *Improved secondary index support. The new secondary index support has been vastly improved. You can read all about it in User Guide - Secondary Indices <http://hypertable.com/documentation/user_guide/#secondary-indices>. *3. *All timestamps passed through the Hypertable APIs now undergo localtime conversion. *4. *Added ability to add and remove secondary indices with the ALTER TABLE <http://hypertable.com/documentation/reference_manual/hql#alter-table> command. *5. *Added a REBUILD INDICES <http://hypertable.com/documentation/reference_manual/hql#rebuild-indices> command. *6. *Improved schema, access group, and column family specifications by making them more uniform. Changed the semantics of the table_alter <http://hypertable.com/documentation/reference_manual/thrift_api/#tablealter> to accept a schema object returned by table_get_schema <http://hypertable.com/documentation/reference_manual/thrift_api/#tablegetschema> and then modified as desired. *7. *Added a Developer Guide <http://hypertable.com/documentation/developer_guide/> to the Hypertable website. This guide illustrates how to build thrift client programs, exercising the various APIs, in all supported languages (Perl TBD). The guide is now auto-generated from a system test, so all of the code examples will remain valid and will compile and run and will not go stale over time. *8. *The query cache now invalidates on row+column_family instead of just the row. This will improve the performance of read heavy applications that use multiple column families. *9. *Upgraded Thrift to > 0.9.1 - Doug -- You received this message because you are subscribed to the Google Groups "Hypertable Development" group.
