 ## Trading immediacy for reduced primary load
 
-Not requiring immediate data consistency allows developers to decide to either:
+We require Sidekiq workers to make an explicit decision around whether they need to use the
+primary database node for all reads and writes, or whether reads can be served from replicas. This is
+enforced by a RuboCop rule, which ensures that the `data_consistency` field is set.
+
+When setting this field, consider the following trade-off:
 
 - Ensure immediately consistent reads, but increase load on the primary database.
 - Prefer read replicas to add relief to the primary, but increase the likelihood of stale reads that have to be retried.
 
-By default, any worker has a data consistency requirement of `:always`, so, as before, all
-database operations target the primary. To allow for reads to be served from replicas instead, we
-added two additional consistency modes: `:sticky` and `:delayed`.
+To maintain the same behavior compared to before this field was introduced, set it to `:always`, so
+database operations will only target the primary. Reasons for having to do so include workers
+that mostly or exclusively perform writes, or workers that read their own writes and who might run
+into data consistency issues should a stale record be read back from a replica. **Try to avoid
+these scenarios, since `:always` should be considered the exception, not the rule.**

 When you declare either `:sticky` or `:delayed` consistency, workers become eligible for database
 load-balancing. In both cases, jobs are enqueued with a short delay.

+        Should define data_consistency expectation.
+
+        It is encouraged for workers to use database replicas as much as possible by declaring
+        data_consistency to use the :delayed or :sticky modes. Mode :always will result in the
+        worker always hitting the primary database node for both reads and writes, which limits
+        scalability.
+
+        Some guidelines:
+        
+        1. If your worker mostly writes or reads its own writes, use mode :always. TRY TO AVOID THIS.
+        2. If your worker performs mostly reads and can tolerate small delays, use mode :delayed.
+        3. If your worker performs mostly reads but cannot tolerate any delays, use mode :sticky.
+
+        See #{HELP_LINK} for a more detailed explanation of these settings.
