* dont check entity ID twice and use single context id length constant
* fix test
* add missing test
* Compile statistics for energy sensors
* Update tests
* Rename abs_value to state
* Tweak
* Recreate statistics table
* Pylint
* Try to fix test
* Fix statistics for multiple energy sensors
* Fix energy statistics when last_reset is not set
* raise an exception when event_type exceeds the max length that the recorder supports
* add test
* use max length constant in recorder
* update config entry reloaded service name
* remove exception string function because it's not needed
* increase limit to 64 and revert event name change
* fix test
* assert exception args
* fix test
* add comment about migration
* Add index to old_state_id column for older databases
The schema was updated in #43610 but the index was not
added on migration.
* Handle postgresql missing ondelete
* create index first
By default these tables are created with utf8 which can only hold 3 bytes. This
meant that all emjoi would trigger a MySQLdb._exceptions.OperationalError because
they are 4 bytes.
This will only fix the issue for users who recreate their tables.
* MariaDB doesn't purge #42402
This addresses home-assistant#42402
Relationships within table "states" and between tables "states" and "events " home-assistant#40467 prevent the purge from working correctly. The database increases w/o any purge.
This proposal sets related indices to NULL and permits deleting of rows.
Further explanations can be found here home-assistant#42402
This proposal also allows to purge the tables "events" and "states" in any order.
* Update models.py
Corrected for Black style requirements
* Update homeassistant/components/recorder/models.py

We currently serialize the event data for state change events
and then replace it because we save the state in the states table.
Since the old state and new state are both contains in the event
the cost of serializing the data has a noticable impact when there
are many state changed events.
