Optimizely Form responses in their own tblBigTable


Is it possible to write all form response data in a separate big table? 

I can probably inherit from DdsPermanentStorage and get something working but I was hoping to do it in a more supported way.

Can't claim to be Form expert but you can inherit DdsPermanentStorage and override GetFormStore which return a store in a separate table. 

but what are your motivations of having Form own table?

Thanks.. yes I do just want a separate table. It doesn't seem very supported; there's no interface to create one, you have to run a SQL script?

Anyway, when I create a separate tblBigTableForms, it is not populating a new's form data. When I create my own DdsPermanentStorage class and override all it's methods, it is just these changes that seem needed:

But on initialising the store on the first form submission, I get: 

It seems that method doesn't create the registration of this form like it normally does; an entry in tblBigTableStoreConfig, multiple in tblBigTableStoreInfo, a VW_FormData and a Save_FormData stored procedure.

As for the motivation.. it's not logical to me, but the client wants it in a separate table for security reasons.

This is how I think it should work - pseudo code obviously so untested. note that this code needs to run first before the table is created. migration is a separate matter

        protected override DynamicDataStore GetFormStore(FormIdentity formIden)
            var dbName = GetFormDbName(formIden);
            return _ddsFactory.GetStore(typeof(Forms)) ?? _ddsFactory.CreateStore(typeof(Forms), CreateStoreParameters());
        internal static StoreDefinitionParameters CreateStoreParameters()
        var storeParameters = Reflector.GetStoreDefinitionParametersForType(typeof(Forms));
        storeParameters.TableName = <Your custom table name>;
        storeParameters.IndexNames.Add("abc"); //add your indexes
        return storeParameters;

Ah yes that's similar to what I had. 
Turns out I hadn't created the new big table properly.

I extracted the EpiServer.Cms.Core.sql statements that had to do with tblBigTable, renamed to my own tblBigTable2 and now it works.
