Aerospike golang ListInsertOp multiple values

Does the ListInsertOp in golang aerospike client support inserting an array of elements ?

If I use https://godoc.org/github.com/aerospike/aerospike-client-go#ListAppendOp, and pass an array ([]string), it just appends the whole array as one value in the list. Am I using it wrong or is there another way to do the same?

Solution

  • ListAppendOp is a variadic function accepting arbitrary number of arguments of type interface{}. If you call it passing your array, it will receive a slice of interface{} ([]interface{}) with a single element which is your array.

    You need to convert your array to a slice of interface{} and expand it using ... when passing it to the function:

    a := []string{"a", "b", "c"}

s := make([]interface{}, len(a))
for i, v := range a {
  s[i] = v
}

ListAppendOp("bin1", s...)
