Hi all:
I am using flink sql with event time, but the field which acts as the
routine is not correct in the output. There’s an eight-hour time difference.
Any suggestion?
My input is (ums_ts_ acts as the rowtime):
{"schema":{"namespace":"en2.*.*.*","fields":[{"name":"ums_id_","type":"long","nullable":false},{"name":"ums_ts_","type":"datetime","nullable":false},{"name":"ums_op_","type":"string","nullable":false},{"name":"key","type":"int","nullable":false},{"name":"value1","type":"string","nullable":true},{"name":"value2","type":"long","nullable":false}]},"payload":[{"tuple":["1","2018-04-11
12:40:01.345123","i","10","aa1","10"]},{"tuple":["22","2018-04-11
12:40:20.345123","u","10","aa2","11"]},{"tuple":["311","2018-04-11
12:40:39.345123","d","10","aa3","12"]}]}
My sql is:
select key, COUNT(*) AS count_sen, SUM(value2) AS
ages,TUMBLE_START(ums_ts_, INTERVAL '1' SECOND) as window_start FROM sen2 GROUP
BY TUMBLE(ums_ts_, INTERVAL '1' SECOND), key;
The output is :
{"schema":{"namespace":"en3.*.*.*","fields":[{"name":"key","type":"int","nullable":true},{"name":"count_sen","type":"long","nullable":true},{"name":"ages","type":"long","nullable":true},{"name":"window_start","type":"datetime","nullable":true}]},"payload":[{"tuple":["10","1","10","2018-04-11
04:40:01.0"]}]}
{"schema":{"namespace":"en3.*.*.*","fields":[{"name":"key","type":"int","nullable":true},{"name":"count_sen","type":"long","nullable":true},{"name":"ages","type":"long","nullable":true},{"name":"window_start","type":"datetime","nullable":true}]},"payload":[{"tuple":["10","1","11","2018-04-11
04:40:20.0"]}]}
