val a = arrayOf(1, 2, 3) println(a.size) // will always be 3 for this array val l = mutableListOf(1, 2, 3) l.add(4) println(l.size) // 4 Array<T> is invariant on T (Array<Int> is not Array<Number>), the same for MutableList<T>, but List<T> is covariant (List<...

Currently, it's impossible to use tuples as arrays, only lists. Array type should be a tuple like (list, tuple). default_types = { "array" : (list, tuple), "boolean" : bool, "integer" : int_types, ... or default_types = { "array" : array...
Represents a strongly typed list of ordered objects that can be accessed by index. Contrary to the Array data type, a List is unbounded, such that its dimension does not need to be specified upon declaration. Instance methods The following methods are available on instances of the List data...

time is spent during query execution. With either of these two types of workload, it is important to make the right decisions early, as re-partitioning large quantities of data can be painfully slow. Simulations of the intended workload are often beneficial for optimizing the partitioning ...
