I have an use case to calculate time difference between events grouped together by transaction command. Example is given below. { "timeStamp": "Fri 2020.03.27 01:10:34:1034 AM EDT", "step": "A" } { "timeStamp": "Fri 2020.03.27 01:10:38:1038 AM EDT", "step": "B", } { "timeStamp": "Fri 2020.03.27 01:10:39:1039 AM EDT", "step": "C" } { "timeStamp": "Fri 2020.03.27 01:10:40:1034 AM EDT", "step": "D" } I have two requirements. Will it be possible to get time difference between consecutive steps ? STEP B 4 sec STEP C 1 sec STEP D 1 sec If above is possible how can I get average elapsed time between two steps for all the transactions which have Step A, B, C, D ? ... View more
