SQLite Data Generator
This is just a super simple utility for creating SQLite databases filled with random data. It's not even a CLI, it just has three variables at the top to change, then compile/run it:
- output directory for the SQLite file
- output filename for the SQLite file
- number of data rows in each table
eg:
outputDir = "Databases"
fileName = "72mb.sqlite"
numRows = 100000
A row count of 100000 makes a 72MB file (taking ~4.5 seconds) on my (old) Linux desktop.
Adjust the variables to suit your desired target file name and size, then run it:
$ go run main.go

Why?
I needed something to generate SQLite files of a specific size, while tracking down a bug which looks related to the size of files being transferred.
