The trick is simple: bundle all the files to be shared into a tarball called shared-files.tar.gz. As there is now only that one file, which name always remains the same, any new install is conveniently clobbering the old version.
In this post, I will explain a little more deeply the physical structure of a SQL Server data file. Unfortunately, I cannot write all the assumptions, behaviours and details about this theme, but you will read a good overview of a file structure and a good start point to understand, and read more, about indexes internals, file fragmentation, transaction log internals and so on… Before we start, let’s remember some vital concepts.
Like every year, Pythian is once again holding a company-wide charity campaign to raise funds and awareness for for men’s health, specifically prostate cancer and male mental health.
