    Cache size in bytes, specified as a positive integer scalar. This value represents the total size, in bytes, of the raw chunk data cache.

    Data Types: double

    Number of elements to hold in the raw chunk data cache, specified as a positive integer scalar.

    Data Types: double

    Preemption policy, specified as a scalar value in the range [0, 1]. A value of 0 indicates that fully read chunks are treated the same as other chunks, that is, preemption occurs based on the Least Recently Used (LRU) algorithm. A value of 1 indicates that fully read chunks are always preempted before other chunks.

    Data Types: double
