This needs a fair amount of tuning, possibly more throttling. It will still evict pages if the compactor gets behind. -TODO ----- - -Sharing my broad TODO items into here. While doing the work they get split up -more into local notes. Adding this so others can follow along: - -(a bunch of the TODO has been completed and removed) -- O_DIRECT support -- libaio support (requires O_DIRECT) -- JBOD support (not in first pass) - - 1-2 active pages per device. potentially dedicated IO threads per device. - with a RAID setup you risk any individual disk doing a GC pause stalling - all writes. could also simply rotate devices on a per-bucket basis. - -on memcached end: -- O_DIRECT support; mostly memalign pages, but also making chunks grow - aligned to sector sizes once they are >= a single sector. -- specify storage size by MB/G/T/etc instead of page count -- cgit v1.2.1
