Issue related with config.use_transactional_fixtures = true

[Rumyantsev Artem]

I use rails 7, clickhouse-activerecord and rspec.

To improve performance I use config.use_transactional_fixtures = true but the clickhouse-activerecord does not supproted and it follows to error:

Do you have any ideas how to fix it and use config.use_transactional_fixtures = true ?

ClickHouse does not support transactions.
