The `concat` kernel concats multiple arrays to contiguous memory. It has the potential to only allocate the required memory. However for (large)-utf8 and for (large)-list it does not do so and relies on exponential allocation to get the required memory. Precomputing the needed capacity of buffers would be faster and less memory heavy. -- This is an automated message from the Apache Git Service.
