Lambda timeout

자정에 한 번만 실행되어야 하는 Lambda 함수가 세 번 실행됐다.

Lambda Schedule -> S3 upload -> RDS insert 이 프로세스에서 세 번 실행된 걸 확인한 것은 RDS.

S3 를 추적해 보았더니 역시나 세 번의 upload.

CloudWatch 의 로그를 보았더니 Lambda 세 번 실행.

왜 세 번 실행이 되었을까...

time out 문구가 눈에 띈다.

15 초로 설정되어 있는건 내가 걸어놨으니 그렇다 치고, S3 upload 는 캔슬되었어야지... 어이가 없네?

timeout 설정 늘려서 해결.
