Hi,
I am attempting to find out the impact of SQL Server Enterprise Edition data compression on the amount of data transferred across a linked server connection.
I found a good article summarising SQL Server Data compression here:
http://shaunjstuart.com/archive/2013/03/enabling-data-compression-in-sql-server/
Shaun suggests, "if you have any servers that will be accessing the compressed databases as a linked server, they will also need to be Enterprise or Developer editions"
So this gives me some hope that the communication between the two servers will send compressed data?
Assume the following scenario:
- I have two Enterprise Edition SQL Servers, one in Australia, one in the UK
- I have a linked server connection running over a WAN, between the two databases
- I have a large table (tblTest) with 100MB of Data (uncompressed)
- I turn on data compression and it drops to 25 MB.
- I then attempt to run a statement like follows:
Insert Into LinkedServer.RemoteDB.dbo.tblTest Select * from LocalDB.dbo.tblTest
How much data would be transferred across the WAN, 100MB or 25MB?
Thanks
