Thread:Talk:Requests for comment/Database field for checksum of page text/Index/reply

Yes, if you want to query by hash then you would need obviously an index but I haven't heard a use case yet where we really would want to query often the hash column. In addition, the checksum will not be always unique across different pages. If two different pages have been blanketed then they would have the same hash. So we might need a compounded index in that case but I would like to hear more different use cases first before we decide on including an index.
