Hi, I have a search that produce the following table Organization|Amount|AcquirerBank
Or_A |2000 |1234
Or_A |4000 |2345
Or_B |1200 |3456
|4020 |4567
Or_C |1456 |5678 And then I have a csv file that provide the bank code with the bank name as a mapping csv as AcquirerBank|BankName
1234 |BankA
2345 |BankB
4567 |BankC
5678 |BankD The target table should look something like this Organization|Amount|AcquirerBank|BankName
Or_A |2000 |1234 |BankA
Or_A |4000 |2345 |BankB
Or_B |1200 |3456 |
|4020 |4567 |BankC
Or_C |1456 |5678 |BankD I try to use join like this index=index
|table Organization, Amount, AcquirerBank
|join AcquirerBank
[inputlookup bank_mapping.csv
|table AcquirerBank, BankName]
|table Organization, Amount, AcquirerBank, BankName But I encounter 2 problems: 1. My index have around a million events, and [join] have a limited number of events it can join, so my result table was lack in result. 2. Also [join] don't show enough results if the mapping csv don't have the data, as the example above, if I use [join], OrB with the field Acquirer that don't exist in mapping csv will not show up. Anyone have a alternative to [join] that can resolve above problems? Thank you in advance.
