I've been reading about the differences between forward indexes and inverted indexes.  Which model does Splunk use?  I have not been able to find that information in the documentation.

Hi @aznewman ,

Splunk uses a time series inverted index, in the form of .tsidx files:

You can read more about how that index is built/populated here:
