Assume there is a single big index file (about 1GB in size) on the server that need to be live 24/7 for queries from web requests. What should I do if I want to update the content of the index file?



I am thinking of first landing the newly updated index file to the same location on the server but with a different file name. Once the file is landed there, I can do a file name swap (which should be very quick) and let the query point to the new file. But if there is a query comes in during the name swapping process, there might be some issue. In this case, how should I deal with the queries during the name swap.
