At the core training I attended last year there was a side note on SSD and write amplification: roughly along the lines of: write amplification can be a big problem with SSD (as writes can be around 4KB but deletes are often in blocks of around 512KB, and that the problem gets worse the smaller and the more random the writes are), but that write amplification is never an issue in ES as all writes are sequential anyway (reading from my notes here).
What does that mean exactly? That write amplification *can* be a big problem with SSD, but not with ES on SSD, or that the problem is relevant with lots of random writes? (I suspect the former, but am not quite sure). -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
