Table update operations

When installing or updating Semantic MediaWiki, an administrator will see an activity report detailing related database schema and table operations.

Schema validation

The database schema is validated and checked against the requirements defined in TableSchemaManager and if necessary, the TableBuilder will initiate a change of related fields or indices.

Selected storage engine is "SMWSQLStore3" (or an extension thereof)

Table optimization

The optimization step was added1 to allow for individual wp:RDBMS back-ends to carry out table specific optimization that can improve the execution plan of queries.

Database initialized completed.

Running table optimization.
   Table smw_object_ids ...
   ... analyze, optimize done.
   Table smw_concept_cache ...
   ... analyze, optimize done.
   Table smw_query_links ...
   ... analyze, optimize done.
   Table smw_ft_search ...

The runtime of the optimization depends on the size of existing tables and the RDBMS system used.

Import

The automatic import2 of data structures is executed after the standard tasks has been completed to deploy information during the installation process before any user interaction takes place.
