This series introduces two configurable options when working with TWCS tables: - `restrict_twcs_default_ttl` - a LiveUpdate-able tri_mode_restriction which defaults to WARN and will notify the user whenever a TWCS table is created without a `default_time_to_live` setting - `twcs_max_window_count` - Which forbids the user from creating TWCS tables whose window count (buckets) are past a certain threshold. We default to 50, which should be enough for most use cases, and a setting of 0 effectively disables the check.
