   device_id bigint(20) NULL,
   v1 double NULL,
   v2 double NULL,
   time_key int(11) NULL COMMENT 'yyyyMMdd',
   ) ENGINE=OLAP
   DUPLICATE KEY(device_id)
   COMMENT 'OLAP'
   PARTITION BY RANGE(time_key)
   (
   PARTITION p202401 VALUES [("20240101"), ("20240201")),
   PARTITION p202402 VALUES [("20240201"), ("20240301")),

   select count(*) from test_event_log
   where time_key = substr('20240301000000', 1, 8) -- can not partition prune
