  • Description
    If you chose delta mode for an index of a table, new data is not written
    to the main index, but to the delta index. This can significantly
    improve performance during indexing. However, if the delta index becomes
    very large, this can have a negative impact on performance when you
    execute queries.
    When the delta index reaches 10% of the main index, the system displays
    a warning.
    Repair
    A MERGE is performed for these indexes in repair mode. The settings are
    retained.

    The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
