Rebuild Product Management Applications Indexes" job long running for 3 days

When building the Item Card in the Redwood page (Product Management Experience → Configure Index → Item), we run the "Rebuild Product Management Applications Indexes" job. However, in lower environments (Test and Dev), this job has been running for three days to complete.

Could you please confirm whether running this job in Production would have any performance impact on other areas due to its long-running nature?

We are in the process of enabling Redwood pages in Production and require urgent feedback
