QVD Data

[buzzy996]

hey guys,

can you assist to share ur experience here on below scenario?

If we try to pull data from one abc.qvd into two xyz.qvws & sdf.qvws(these tow .qvws are different applications) at same point of time(exp:@10am shceduled),what will be happen in real time?

Qvd will fail to produce data to two .qvws or lock?

thanks

As I understand it, the QVD will serve the data requested by the load script(s) into memory, it's not locking rows as per a relational database.

I have never tested it by reading a qvd (writing will be definitely be locked) but I think in general you should avoid such situations.

You can read from qvd's simultaneously afaik. But if the qvd is written to then it is locked by the writing process and cannot be read by another process.
