on disk index

The index IRadix will take too much memory, I am going to find some approachs based on disk, like a hashtable.

Index on disk? Wouldn't random reads and writes to disk slow down access tremendously?

It depends on how we design and implement it, it may slow down the read and write performance, but it will save much memory to store more data.
