arrayConcat

Description

Returns a new array by concatenating the elements of two arrays into a single array.

• Both arrays must be of the same element type.
• Supported element types include string, bool, number, interval, timestamp, regexp, and enum.

Syntax

Like many functions in DataPrime, arrayConcat supports two notations, function and method notation. These interchangeable forms allow flexibility in how you structure expressions.

arrayConcat(array1: array<T>, array2: array<T>): array<T>

(array1: array<T>).arrayConcat(array2: array<T>): array<T>

Arguments

Example

Use case: Combine job queues into a single view

Suppose you want to view both processing and loading jobs in a single list. Consider the following input:

{
    "processing_jobs_waiting": ["job1", "job2", "job3"],
    "loading_jobs_waiting": ["loading_job1", "loading_job2", "loading_job3"]
}

By concatenating the arrays, you can see all jobs together in one array for simplified analysis.

create all_jobs from arrayConcat(processing_jobs_waiting, loading_jobs_waiting)

create all_jobs from processing_jobs_waiting.arrayConcat(loading_jobs_waiting)

Output

The result will combine both arrays:

{
    "processing_jobs_waiting": ["job1", "job2", "job3"],
    "loading_jobs_waiting": ["loading_job1", "loading_job2", "loading_job3"],
    "all_jobs": ["job1", "job2", "job3", "loading_job1", "loading_job2", "loading_job3"]
}
