Options for offline reorganization of HALDB databases

You have several options when reorganizing a HALDB database.

Your options for reorganizing a HALDB database include:

• You can reorganize any number of partitions. If you need to reorganize only one partition, you can unload and reload it without processing other partitions.
• You can reorganize partitions in parallel or you can reorganize the database with one process. The degree of parallelism is determined by the number of reorganization jobs you run. Each job can process one or multiple partitions. To increase the parallelism, you can increase the number of reorganization jobs and decrease the number of partitions each job processes.
• You can reuse existing database data sets or you can delete them after they are unloaded and allocate new data sets for the reload.
• You can add partitions, delete partitions, or change partition boundaries.
