What if we use ClickHouse (which is a columnar analytical database) as our main datastore? Well, typically, an analytical database is not a replacement for a transactional or key/value datastore. how many messages was send for some time period and how much it cost) and a typical key/value queries like: “return 1 message by the message id” Using a columnar analytical database can be a big challenge here. Loading the JSON data to Clickhouse.
