To simulate text messages I have used ~3 billion of reddit comments (10 years from 2007 to 2017), downloaded from pushshift.io. With the latest ClickHouse version, all of these features are available, but some of them may not perform fast enough. No secondary indexes means that point selects (select by ID) tend to be very slow.
