1. I am using array-tuple in OPL. I manually exported (since your script does support this format) and fed WML, but I got an following error.

2. I am also using a following tuple format that is not supported by your script.

I flatten the array tuple by adding machine ID into b1(1000*MchID+b1) and b2 (1000*MchID+b2) fields and assign "types" of (mch.id*1000+jid) to a sequence. It works ok with a small problem, but it got really slow when the size gets bigger. How to avoid this performance issue coming from flattening tuples?

tuple t_Travel {

I flatten the array tuple by adding machine ID into b1(1000*MchID+b1) and b2 (1000*MchID+b2) fields and assign "types" of (mch.id*1000+jid) to a sequence. It works ok with a small problem, but it got really slow when the size gets bigger. How to avoid this performance issue coming from flattening tuples?

tuple t_Travel {
key int b1; key int b2; int d;
}; {t_Travel} DataK[Mchs];

tuple t_Travel {
key int b1; key int b2; int d;
}; {t_Travel} DataFlatten; //

    range r=1..2;        int a1[r]=[1,2];    int a2[r]=[1,4];    {int} set1={5,6};    {int} set2={9,10};    tuple t    {    string firstname;    int number[r];    {int} intset;    }    {t} s={<"Nicolas",a1,set1>,<"Alexander",a2,set2>};        tuple t2    {      string firstname;      int keynumber;      int number;      int intset;    }        {t2} s2;        execute    {      for(var i in s)        for(var j in r)           for(var k in i.intset)             s2.add(i.firstname,j,i.number[j],k)      for(var l in s2 )writeln(l);    }  

which gives

Using your script, I have successfully exported most of tuple data into csv files, but I see two errors. I imagined a smooth transitioning from OPL environment to WML, but it is not. Sad..

1. I am using array-tuple in OPL. I manually exported (since your script does support this format) and fed WML, but I got an following error.

[2021-03-10T23:03:38Z, INFO] Element 'DataK' provided in CSV data source cannot be mapped to OPL type: 'ARRAY' as this type is not supported for input data on the Cloud.

tuple t_Travel {
key int b1; key int b2; int d;
}; {t_Travel} DataK[Mchs];

2. I am also using a following tuple format that is not supported by your script.

tuple t_Mx {
key int job;
{int} mch;
}; {t_Mx}

[2021-03-10T23:03:38Z, SEVERE] expecting a collection and found an integer/float

Can you please suggest any solution?

I have successfully tested a same code on both WML (w/ basic configuration) and local OPL. I don't believe this result. WML cloud delivered a slower computation compared to my own laptop. I will try WML with full configuration in coming weeks, but I cannot understand.

I flatten the array tuple by adding machine ID into b1(1000*MchID+b1) and b2 (1000*MchID+b2) fields and assign "types" of (mch.id*1000+jid) to a sequence. It works ok with a small problem, but it got really slow when the size gets bigger. How to avoid this performance issue coming from flattening tuples?

tuple t_Travel {
key int b1; key int b2; int d;
}; {t_Travel} DataK[Mchs];

tuple t_Travel {
key int b1; key int b2; int d;
}; {t_Travel} DataFlatten; //

    range r=1..2;        int a1[r]=[1,2];    int a2[r]=[1,4];    {int} set1={5,6};    {int} set2={9,10};    tuple t    {    string firstname;    int number[r];    {int} intset;    }    {t} s={<"Nicolas",a1,set1>,<"Alexander",a2,set2>};        tuple t2    {      string firstname;      int keynumber;      int number;      int intset;    }        {t2} s2;        execute    {      for(var i in s)        for(var j in r)           for(var k in i.intset)             s2.add(i.firstname,j,i.number[j],k)      for(var l in s2 )writeln(l);    }  

which gives

 <"Nicolas" 1 1 5> <"Nicolas" 1 1 6> <"Nicolas" 2 2 5> <"Nicolas" 2 2 6> <"Alexander" 1 1 9> <"Alexander" 1 1 10> <"Alexander" 2 4 9> <"Alexander" 2 4 10>

Using your script, I have successfully exported most of tuple data into csv files, but I see two errors. I imagined a smooth transitioning from OPL environment to WML, but it is not. Sad..

1. I am using array-tuple in OPL. I manually exported (since your script does support this format) and fed WML, but I got an following error.

[2021-03-10T23:03:38Z, INFO] Element 'DataK' provided in CSV data source cannot be mapped to OPL type: 'ARRAY' as this type is not supported for input data on the Cloud.

tuple t_Travel {
key int b1; key int b2; int d;
}; {t_Travel} DataK[Mchs];

2. I am also using a following tuple format that is not supported by your script.

tuple t_Mx {
key int job;
{int} mch;
}; {t_Mx}

[2021-03-10T23:03:38Z, SEVERE] expecting a collection and found an integer/float

Can you please suggest any solution?
Thanks,
