> Index has about 600+ columns，average size of doc is relatively big, Lucene firstly obtain the original doc from disk and then merge the old and the updating coulmns to a new one,finally flush to disk.
> The dsik io usage rate of our 150+ nodes always reach nearly 99% while partly updating requests call frequently.
> I want to optimize the partly updating strategy, only partly columns instead of all are obtained and merge into a new one while partly updating request calls,in purpose of cuting down disk io usage rate.
> is there any suggestions?
