Hi,

I have the following Table :
CREATE TABLE users (
uid INTEGER PRIMARY KEY AUTOINCREMENT,
username VARCHAR(100) UNIQUE NOT NULL DEFAULT '',
email VARCHAR(255) UNIQUE NOT NULL
}

I wanted to know if I create an INDEX for the column "email" what isg going
to be the extra space the index will occupy ? By extra space I mean the
extra amount of disk space required by the index ?

I tried to search for any docs on this but couldnt.
This table is going to have 1 Million records and I need to save space here.
Adding an index makes the lookup very fast.

Regards,
