Function sentinelScriptRetryDelay

app/redis-6.2.6/src/sentinel.c:897–902

How much to delay the execution of a script that we need to retry after * an error? * * We double the retry delay for every further retry we do. So for instance * if RETRY_DELAY is set to 30 seconds and the max number of retries is 10 * starting from the second attempt to execute the script the delays are: * 30 sec, 60 sec, 2 min, 4 min, 8 min, 16 min, 32 min, 64 min, 128 min. */

 * starting from the second attempt to execute the script the delays are:
 * 30 sec, 60 sec, 2 min, 4 min, 8 min, 16 min, 32 min, 64 min, 128 min. */
