I know this is probably something most people don't want to do, but I have an issue with the \_id field taking up a significant amount of the JVM on my nodes. Is there a way to disable this? I don't need direct document lookup and it's 98% of the segment memory. Or is there any more intelligent way to deal with this problem as my indices can get over 1B documents which can get over 1GB of the JVM heap.
