	created DATETIME default now()
)
ENGINE = MergeTree()
ORDER BY created
;

INSERT INTO events (eid, ip, etype, price, created)
VALUES
	(1, '192.168.1.1', 100, 1000000, '2022-10-01 12:00:00'),
	(2, '127.0.0.1', 100, 1000000, '2022-10-02 12:00:00'),
	(3, '192.168.1.1', 100, 1000000, '2022-10-03 12:00:00'),
	(4, '127.0.0.1', 200, 1000000, '2022-10-01 12:00:00'),
