Why there is no per-event price
Analytics vendors charge per event because they store your events. Infralytiqs does not store your events — your ClickHouse server does. So there is no volume for us to meter, and no incentive for us to make sampling sound reasonable.
The practical consequence is that your analytics bill becomes a storage bill you already understand. With ZSTD codecs and LowCardinality dimensions on the event table, that bill is usually smaller than people expect — and if it ever is not, you change one TTL clause instead of negotiating a contract.
