Creating an index: New Index Max Size vs Retention

[aohls]

I am looking to setup a new summary index. When creating the index how does Max Size of Entire Index and Retention interact with one another. Would data get removed once one of these settings are hit? For example if I have 5GB and set the retention to 30 days, if I exceed 5GB at 20 days will it truncate the oldest days at that time; and the same if I set the retention to 30 days but only have 2GB out of 5 used, will it start truncating the old data?

If maxTotalDataSizeMB(index size) is reached before frozenTimePeriodInSecs(retention period), data will be rolled to frozen before the configured time period has elapsed. If archiving has not been configured, unintended data loss can occur.

also if frozenTimePeriodInSecs(retention period) is reached before the index size of 5 gb is not reached , data will be rolled to frozen.

so in theory whatever reaches first will be applicable.

@Mayurmpatil Thank you. We are just starting to use the summary index so this is helpful.
