Restore the entire Elasticsearch index from the database via Commander service.

Changes in the object structure might lead to differences between the index of Elasticsearch and the database. As of yuuvis® Momentum version 2020 Winter, it is possible to reindex Elasticsearch according to the database by means of the dbs-reindex command provided by the Commander service.

The reindexing can be limited by a start date and an end date, and by specifying a tenant. Per default, the command is executed in a simulation mode that does not manipulate any data. In order to actually apply the reindexing to the data, the simulation mode has to be turned off with the dbs-configure Command. After the non-simulation reindexing has been executed, the simulation mode is turned on again automatically.

These parameters can be given to the dbs reindex command:

The following example code shows the commands together with the corresponding command line outputs for a non-simulation reindexing. The simulation mode is turned off in line 7. In line 18, the reindexing is executed for the default tenant starting from 2017-01-01 and ending on 2017-12-31.
