The HAF documentation says (https://gitlab.syncad.com/hive/haf/-/blob/develop/src/hive_fork_manager/Readme.md#important-notice-about-irreversible-data):

Important notice about irreversible data
⚠ Although reversible and irreversible block tables are directly visible to apps, these tables should not be queried directly.

As I see in the code all indexes are created on irreversible blocks data tables. Looking at the views they also are created on the irreversible data. Are You sure that new indexes are required additionally to those that are already present in HAF ? Without using views incorporated in the HAF You won't be able to present together irreversible and reversible data (live data). Please let us know if HAF is too slow for Your application, You may add a new issue. Maybe we can incorporate some changes directly inside HAF.
