* Chunk MariaDB data migration to avoid running out of buffer space This will make the migration slower but since the innodb_buffer_pool_size is using the defaul to 128M and not tuned to the db size there is a risk of running out of buffer space for large databases * Update homeassistant/components/recorder/migration.py * hard code since bandit thinks its an injection * Update homeassistant/components/recorder/migration.py * guard against manually modified data/corrupt db * adjust to 10k per chunk * adjust to 50k per chunk * memory still just fine at 250k * but slower * commit after each chunk to reduce lock pressure * adjust * set to 0 if null so we do not loop forever (this should only happen if the data is missing) * set to 0 if null so we do not loop forever (this should only happen if the data is missing) * tweak * tweak * limit cleanup * lower limit to give some more buffer * lower limit to give some more buffer * where required for sqlite * sqlite can wipe as many as needed with no limit * limit on mysql only * chunk postgres * fix limit * tweak * fix reference * fix * tweak for ram * postgres memory reduction * defer cleanup * fix * same order
