Memory Pooling And Buffer Management For Efficient Allocation

Cross-language columnar memory format for zero-copy data.

Unique: Pluggable memory pool abstraction with support for multiple allocators (jemalloc, mimalloc, system malloc) and memory limit enforcement, enabling applications to control memory usage across all Arrow operations

vs others: More flexible than system malloc because it enables custom allocators and memory limits; more transparent than manual memory management because pools track all allocations automatically
