Is there a way to share a Data Model across 2 Search Head Clusters

[ctaf]

Hi,

We would like to use the same Data Model (same field extractions, same events, same acceleration window, etc.) in two different SH Clusters. Is it possible to do it without having to compute and store the acceleration files twice on the indexers?

Thank you!

Shared datamodels are available as of Splunk 8x https://docs.splunk.com/Documentation/Splunk/latest/Knowledge/Sharedatamodelsummaries

It looks like this is now possible with the new Splunk version 8.0

This would be a great feature to let search heads subscribe to datamodels generated by other search heads. The main reason being is datamodel generation is really a batch-like process. This way we could could silo datamodel generation to limit the impact to users on the same search heads without having to overbuild the user search tier. These are some advantages of summary indexes and metrics indexes where they can be accessed by search heads which did not create them.

That is not possible. Quote from the relevant documentation:

Summaries are restricted to a
particular search head (or search head
pool ID) to account for different
extractions that may produce different
results for the same search string.
