Multiplication of values in Jolt Transformation Spec - json

Question

I have input as shown below, If timeMeasurementUnitCode="DAY" then value I need to calculate as value*24*60, if timeMeasurementUnitCode="HOUR" then value value*60
I see there is one similar use case people are looking for, the ticket is opened on Jul 17, 2019: https://github.com/bazaarvoice/jolt/issues/832
Issue 832 seems still open now
Input:
{
"freightCharacteristics": {
"transitDuration": {
"timeMeasurementUnitCode": "DAY",
"value": 6
},
"loadingDuration": {
"timeMeasurementUnitCode": "HOUR",
"value": 6
}
}
}
Expected output: Based on the constant provided in the input as DAY or HOUR, I need to multiple no.of days*hours*minutes to arrive at my requirement as shown below.
{
"transitDurationInMinutes" : 8640,
"loadingDurationInMinutes" : 360
}
]
As per the suggestion from #mattyb, I used divide function to achieve what want to achieve by multiplication, logic is updated as below.
[
{
"operation": "shift",
"spec": {
"freightCharacteristics": {
"transitDuration": {
"timeMeasurementUnitCode": {
"DAY": {
"#(2,value)": "transitDurationInMinutes"
},
"*": {
"#(2,value)": "transitDurationInMinutes"
}
}
},
"loadingDuration": {
"timeMeasurementUnitCode": {
"HOUR": {
"#(2,value)": "loadingDurationInMinutes"
},
"*": {
"#(2,value)": "loadingDurationInMinutes"
}
}
}
}
}
},
{
"operation": "modify-overwrite-beta",
"spec": {
"transitDurationInMinutes": "=divide(#(1,transitDurationInMinutes),0.00069444444)",
"loadingDurationInMinutes": "=divide(#(1,loadingDurationInMinutes),0.01666666666)"
}
},
{
"operation": "modify-overwrite-beta",
"spec": {
"transitDurationInMinutes": "=toInteger",
"loadingDurationInMinutes": "=toInteger"
}
}
]

Answer 1

Another option would be making DAY and HOUR literals object keys respectively in order to pick them conditionally within the next step such as
[
{
"operation": "shift",
"spec": {
"*": {
"*": {
"value": "#(1,timeMeasurementUnitCode).&"
}
}
}
},
{
"operation": "modify-overwrite-beta",
"spec": {
"DAY": {
"val": "=divide(1,#(1,value))",// 1/6 will be used to simulate a multiplication
"div": "=divide(1440,#(1,val))",
"transitDurationInMinutes": "=toInteger(#(1,div))"// to eliminate decimal representation which ends with ".0"
},
"HOUR": {
"val": "=divide(1,#(1,value))",
"div": "=divide(60,#(1,val))",
"loadingDurationInMinutes": "=toInteger(#(1,div))"
}
}
},
{// get rid of object keys
"operation": "shift",
"spec": {
"*": {
"*Duration*": "&"
}
}
}
]
