Overview

WDOptimizer

The different operations that can be performed with WDOptimizer are as follows:
  • Optimizing the indexes
    This option allows you to perform several types of operations:
    1. Check the indexes: Checks the consistency between the index and the data files.
    2. Optimize speed of indexes (Re-calculate statistics): Optimizes the indices by calculating index statistics. These statistics are used to optimize the filters, the queries and the HFSQL views.
      Remark: The more the data file is modified, the less the statistics reflect the content of HFSQL data file. The more records the data file contains, the less the modification of a single record impacts the overall statistics.
    3. Rebuild the indexes: Optimizes the access to the records of the data file and recalculates the statistics. All the crossed records are automatically deleted.
    4. Rebuild the indexes and the memos: Optimizes the entire data file, its index and its memos.
    5. Check and compress the indexes and the memos: Optimizes the entire data file, its index and its memos. The memos will be compressed. Advanced options are available ("Options for compressing the memos").
