I have a CDB database with 1 Million to 10 Million records .. This is just a
key where the app needs to lookup if an entry exists or not.  I dont need
the value.  My app will be looking up the key_exists() almost 100 times a
second

What is the fastest way of implementin this

I have a few questions

1) Is CDB the best way of storing such data
2) Is CDB_File optimized for readonly lookups
3) Is it recommended to have an in memory hash .. If memory is not an issue
?
