• Chose B1

  Retry the query with exponential backoff, up to a cap of 15 minutes.

• Chose B1

  Exponential backoff avoids swamping the server. Higher rates may only make problem worse. Front-end should not have option to restart DB.

  We should use exponential backoff because it reduces load on the failing database, optimizes retry timing and is the industry best practice. Exponential backoff is a retry strategy where the wait time between retry increase exponentially. By gradually increasing the retry interval, the system avoids wasting resources on immediate retries when the database is likely still down.
