Mimalloc

OpenObserve has a feature to use Mimalloc as memory management for Rust.

But default we didn't enable it, if you want enable should add cargo flags like this:

RUSTFLAGS='-C target-cpu=native' cargo build --release --features mimalloc

if you want better control to release memory quickly, you can set some environments

export MIMALLOC_VERBOSE=1
export MIMALLOC_PAGE_RESET=1
export MIMALLOC_DECOMMIT_DELAY=25
