Thanks for the quick response. TWCS is used.

Probably not in any measurable way.

No. Nothing measurable. In fact it should be beneficial if paired with TWCS

Hi everyone

We are collecting monitoring data in excess of 100K TPS in Cassandra.

All data is time series data and must have a TTL.

Currently we have set default_time_to_live on the table.

Does this have a negative impact on Cassandra throughput performance?

Thank you in advance.
