In a previous blog, I reviewed Virtual Table Server and its history with LoadRunner. I wrote about many of my friends in the testing community who have contributed to it, talked about it, and used it in practice. Today, I want to introduce you to ANOTHER one of my longtime friends, Ed Leno of Solution Maniacs. He has decided to create a new utility application called SQUID (Simple Queues of Independent Data) that takes the concept of VTS to another level.
For many long-time users of LoadRunner, Virtual Table Server (VTS) has been an unsupported tool that many of us have relied upon to solve dynamic data dependency issues under load. VTS is a virtual data file that multiple load generators can reference to create, modify, and consume data Think of it as a “living” data file (or table) that runs in memory.
