mirror_subs_allowed_to_use_staging_store
Use this system parameter at the subscription level to allow the user to control access to the shared scrape staging store for individual subscriptions.
This parameter can be set at the subscription level through dmSet utility (MC only allows setting and viewing the instance-level setting for a property).
Use this system parameter at the subscription level to allow the user to control access to the
shared scrape staging store for individual subscriptions.
Note: This property is different from the
use_staging_store property. While use_staging_store determines whether the staging store is enabled
at all, the current property is used to control access to the shared scrape staging store for
specific subscriptions.
Recommended configuration approaches based on subscription usage of the shared scrape staging store:
- If most subscriptions can use the shared staging store and only a few cannot, it is best to keep the instance-level setting as true (the default). Then, set the property to false at the subscription level for those few subscriptions that need to use a private log reader or parser instead.
- Conversely, if most subscriptions cannot use the staging store and only a few can, set the instance-level setting to false. Then, set the property to true at the subscription level for those specific subscriptions that are allowed to use the shared scrape staging store.
Note: Even if a subscription is allowed to use the shared staging store, it may still default
to using a private log reader or parser. This can occur if the subscription falls significantly
behind or moves ahead of other subscriptions by using the shared staging store.
