I’m not a database guy and I only know enough SQL to get me through whatever task I need ro be complete. I used MemSQL at my last job and it seemed like an interesting idea. Can open source solutions provide the same features as MemSQL, MSSQL, and Oracle. can one db provide all of the features as the three above? If so, are there any technical reasons to go with them? Or any proprietary database. My intiution is that they are probably providing less and less value over time as the tech and knowledge diffuse into the open sphere. Is this true? I would appreciate some answers to the above questions!
