  Returns Promise<void>

getExpiresAfterSeconds

• getExpiresAfterSeconds(): number

• Retrieve the number of seconds that records will be kept in the persistence store

  Returns number

getRecord

• getRecord(data): Promise<IdempotencyRecord>

• Retrieves idempotency key for the provided data and fetches data for that key from the persistence store

  Parameters
