But you will face problems with the currently available tools in DSPAM. The one problem is that the tools for the hash driver are not very rock solid and the second problem is that people use the hash driver when using the Sparse Binary Polynomial Hashing tokenizer. The token data from the hash driver could be migrated to MySQL but you will have a hard time to continue using those tokens (when using SBPH) with the MySQL driver since you will probably change the tokenizer when switching to MySQL. I am pretty sure you will change the tokenizer. Using SBPH with MySQL will be almost not possible since SBPH creates so much tokens that your MySQL installation will suffer from so much tokens. To make the story short: Start with fresh data when switching from hash to MySQL. > -- > Simon St.Laurent > http://simonstl.com > Steve > > !DSPAM:1011,4967547d150921435512920!
