 * Default value is `0`
 
 The number of times to re-run the query after the first failure. If the query fails after all retries, it logs an error message.
 The default is 0 (no retry). This value should be equal to or greater than zero.
 
+NOTE: Partial failures - such as errors in a subset of all slices - can result in the entire query being retried, which can lead to duplication of data. Avoiding this would require Logstash to store the entire result set of a query in memory which is often not possible.
