Hi Cliff - A write unit does not correspond to a single INSERT. A single INSERT with less than 16MB of data generates ~0.01 “write unit”, so a single “write unit” typically corresponds to ~100 INSERTs. In your example, that would come closer to $11 a day. Depending on how small of batches you plan to write in that examples, there may be ways to reduce that spend further, by batching even more or turning on "async_insert" inside ClickHouse.
