Publish and synchronize repeated export

Automatic execution of the Publish & Synchronize process does not always resolve all your tasks. For example, you might want to re-synchronize(re-sync) the published data in Redis and Elasticsearch to display updated information in your shop front end. Or you might want to regenerate the published data and re-write the data of the database tables in the Storage and Search modules with the subsequent update of Redis and Elasticsearch records. This can be done manually by running console commands.

Data re-synchronization

In some cases, you might want to re-export data into Redis and Elasticsearch. For example, if Redis has been flushed and the data in Redis and/or Elasticsearch is lost.

To re-export data, run the following command:

vendor/bin/console sync:data

This command does the following:

1. Reads the aggregated data from the database tables of Storage and Search modules.
2. Sends the data to the RabbitMQ queues.
3. Copies the data from the RabbitMQ queues to Redis and Elasticsearch.

You can specify particular Storage and Search tables by specifying entity names as follows:

vendor/bin/console sync:data {resource_name}

For example, the command to re-sync data for CMS Block looks as follows:

vendor/bin/console sync:data cms_block

To trigger data re-sync for a resource, there must be a corresponding sync plugin created for this resource. To learn how to create it, see Implement synchronization plugins

Published data re-generation

You can regenerate published data from scratch. For example, something went wrong during a product import and you want to re-publish the data. In other words, you need to update Storage and Search tables and sync the data in Redis and Elasticsearch.

To regenerate published data, run the following command:

vendor/bin/console publish:trigger-events

This command does the following:

1. Reads data from the Storage and Search tables and re-writes them
2. Updates Redis and Elasticsearch records.

You can specify particular Storage and Search tables by indicating resource names as follows:

vendor/bin/console publish:trigger-events -r {resource_name}

Also, you can add one or more entity IDs:

vendor/bin/console publish:trigger-events -r {resource_name} -i {ids}

For example, the command to regenerate the published data for CMS Block and Availability resources with IDs 1 and 2 looks as follows:

vendor/bin/console publish:trigger-events -r cms_block,availability -i 1,2

To trigger data re-publish for a resource, there must be a corresponding publisher plugin created for this resource.

To learn how to create it, see Implement event trigger publisher plugins.
