**Versions** (relevant - OpenSearch/Dashboard/Server OS/Browser):  
2.5

**Describe the issue** :  
Is there any way to change the backing indices naming convention created by data stream. Currently if the data stream name is **test\_data\_stream** , then backing indices (upon rollover) are created as

1. .ds-test\_data\_stream-000001
2. .ds-test\_data\_stream-000002
3. .ds-test\_data\_stream-000003

Is there any way to control naming convention and instead of 000001 or 000002, provide rollover date or index creation date. ex: .ds-test\_data\_stream-2023-05-30 ?

**Configuration** :

Hey,

I was unable to modify it also. It might be there by default.
