Cleanup indexes as >50% of the db size was indexes,
many of them unused in any current query
Logbook search was having to filter event_types without
an index:
Created ix_events_event_type_time_fired
Dropped ix_events_event_type
States had a redundant keys on composite index:
Dropped ix_states_entity_id
Its unused since we have ix_states_entity_id_last_updated
De-duplicate storage of context in states as
its always stored in events and can be found
by joining the state on the event_id.
Dropped ix_states_context_id
Dropped ix_states_context_parent_id
Dropped ix_states_context_user_id
