I don't need this for myself, I use command line. :) I'm writing article intended for audience that may not have access to command line or php settings on shared hosting.
If you aren't familiar with it Big Dump it's a php script used for staggered import of large databases so you can skirt php limitations. The SQL file can be uploaded via FTP and the script runs the queries in batches. It's not compatible with php7 so I need alternative. Surprisingly I'm running into brick wall for alternatives.
