@jacques-n I think we have several choices: we can try implement a c++ memory pool which is backed by a Java Allocator, actually I have a PoC branch for that: https://github.com/zhztheplayer/arrow-1/tree/ARROW-7808-wip-bridged-allocator. Or we can continue hacking Java API to reserve direct memory after buffer is registered. The reservation should happen inside Netty API because Netty has its own direct memory counter: https://github.com/netty/netty/blob/cbe238a95bab238455e3ff1849d450a9836f39ef/common/src/main/java/io/netty/util/internal/PlatformDependent.java#L749-L766 Which one do you suggest or maybe there's a better one than both? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
