Last week we finally started receiving ATLAS TAG data through the Oracle Streams, so we are now keeping an eye on how the users are going to consume such a "fancy" service. Selecting events directly querying an Oracle DB sounds fancy... at least to me :-)
I think in the end we allocated around 4 TB of space for this DB, so it will also be the largest DB at PIC.
All in all, an interesting exercise for sure. I hope now users will come in herds to query the TAGs like mad... there we go.
