Index Service Task Queue Reader 

Use

System-internal index management tasks that trigger indexing, for example, should only be carried out in a certain CM installation in a load-balancing environment. This CM installation must be entered beforehand in the configuration of the index service task queue reader.

In contrast to the content exchange task queue reader , the index service task queue reader carries out tasks that are gathered in a queue.

 

Prerequisites

The index management service is activated.

 

Features

If index management tasks have already been carried out on any of the CM installations in the load-balancing environment, a corresponding request is written to the index service task queue. The index service task queue reader is now executed on a specified system, and reads the index service task queue once a minute. If a relevant task is found, it is then executed.

 

The following tasks are executed by the index service task queue reader:

·        Indexing

·        Deindexing

·        Reindexing

·        Incremental update of indexes

·        Incremental update of indexes by data source

·        Taxonomy training with an existing hierarchy

·        (For query-based taxonomies): Updating taxonomies
