We are considering using a tool from Red Gate called SQL Data Compare for keeping four databases in sync.
I was at a Microsoft seminar last night which was being sponsored by Red Gate, so I asked them about the performance of SQL Data Compare, I said something like "do you have any figures for what volume of data it can support?" - first reaction:
"volume isn't one of its strong points"
I tried to press them that I wasn't looking to sync millions of transactions, I just wanted some idea of what it would be reasonable to expect from the tool, but the two people I was speaking to were both very cautious about it - "use where clauses to limit the data being loaded", "there is a lot of discussion about this on the newgroups, take a look at them", "there are really too many variables to give any figures".
I don't understand why they are so cautious. I had a look at product reviews for the tool - using Google - and they all appear very positive. Can anyone who uses the tool regularly give any rough figures for the amount of data it will process in a given period?
