Figured it out (thanks to this guy for the clue). Had to raise the TTL on the logs table, as it's 15 days by default - and I was trying to insert some archived log data from September. Please, document it here that
...TTL toDateTime(timestamp / 1000000000) + toIntervalSecond(1296000)
is how you define the retention duration - it's not obvious for someone who's got no clickhouse experience.
Great that you were able to figure this out @vandr0iy
Will improve the docs
