Does `maxTotalDataSizeMB` apply to all indexes in one indexer?

[splunkuser1948]

I am beginner in splunk and I had a doubt related to maxTotalDataSizeMB property.

Assume, I have only one indexer. Now I have created many indexes like web_app , iot etc.
Now, a separate index Db created for them in our only indexer.
Now, when we mention value of maxTotalDataSizeMB , does this apply to all indexes Db size in our only indexer
or individually on each one of them ?

It depends on where you define it within indexes.conf

This would apply to all indexes:

[default]
maxTotalDataSizeMB = 650000

To set it on a per index basis:

[index_01]
maxTotalDataSizeMB = 2500

[index_01]
maxTotalDataSizeMB = 3000

Eh, typo there sorry. Should be index_01 and index_02, but you get the idea.
