12 Database handling

    13 -----------------

    14 

    15 * Most indexes and constraints will be rebuilt during the migration, because

    16   they are now named after a md5 hash to control the name's size.

    17 

    18 * Index are renamed upon renaming of an entity type, so they are still

    19   correctly tracked.

    20 

    21 * A new `db-check-index` command is added to `cubicweb-ctl`, to display the

    22   differences between the indexes in the database and those expected by the

    23   schema. It's recommended to run this command after the migration to 3.23 and

    24   to adjust things manually for cases that are not easily handled by the

    25   migration script, such as indexes of entity types that have been renamed. It

    26   should be mostly about dropping extra indexes.

    29 Data-import

    30 -----------

    31 

    32 * Deprecated `MetaGenerator` in favor of slightly adapted API in

    33   `MetadataGenerator` (more consistent, giving more control to sub-classes and

    34   suitable for usage with the `MassiveObjectStore`)

    35 

    36 * Major cleanups of the `MassiveObjectStore` and its `PGHelper` companion

    37   class:

    38 

    39   - dropped a bunch of unnecessary / unused attributes

    40   - refactored / renamed internal methods

    41   - added support for a metadata generator, the now recommended way to control

    42     metadata generation
