Overview

Custom error representing a serious error. If one individual record is larger than the max bytes allowed, db_blaster "fails fast". If we ignored this record and moved on, it would never make it to SNS as its updated_at would end up being less than the last processed record. Possible fixes:

  1. if possible ignore the column(s) that are too large
  2. manually move the record to the intended destination
  3. bug me to provide an S3 workaround
