array.from() creates a table from a list of records. Does anyone know of a way I can do the opposite and construct a list of records from a table? I’d like to then use dict.fromList to create a dictionary from that list of records, but I can’t find a way to make it work.
Let’s assume I have some table that is formatted such:
lookupTable = someOtherTable
|> map(fn: ® => ({r with
key: r.name,
value: r.color
}))
|> keep(columns: [“key”, “value”])
so, now I’d like to do this:
lookupDict = dict.fromList(pairs: lookupTable)
so that I can write a function like this:
findColor = (n) => dict.get( dict: lookupDict , key: n, default: “” )
The idea here is to be able to use this dictionary lookup rather than a join which takes an incredibly unfortunate huge amount of time.
This fails though at the dict.fromList with:
error calling function "fromList" @34:19-34:71: keyword argument "pairs" should be of an array of type object, but got an array of type [t5751]
Thanks for any suggestions.
