Question

What is the difference between the Consistency Check job and the Re-Indexing job?

Answer

Consistency Check job - The job is to resolve inconsistencies between primary and secondary storage.

It is performed: 
1. During Search issues
2. Merge Issues
3.If loaded data is not visible in the tenant
4.If we enable the search by OV feature on a tenant
5.Inconsistency issue (Recommended is ES consistency check task if the issue is not resolved then go for Reindex)

For More Info check out the Reference section below.

Re-Indexing Jobs - 

This task compares entities between the Data Keyspace and ES search indexes and resolves basic inconsistencies if found. If some entities are present in the search but not present in the main data storage, this task removes these entities from the search storage. If some entities are present in the main storage but not present in the search, the task tries to reindex such entities.
