We have 26gb of data dump from discourse 1.3million users 3million topics 21million posts our problem is we are importing at 500k/min but after a few minutes it decreases up to 2k/min

You’ll need lots of ram. You might look at the bulk importers, but I don’t believe that there is one for vanilla.

You will need a CPU from the top of PassMark CPU Benchmarks - Single Thread Performance if you want to run the regular import script as fast as possible. I have no idea what you get on AWS or any other cloud provider with vCPUs. :man_shrugging:

You want to use the bulk importer.

[Screen Shot 2020-11-06 at 2.42.12 AM] whenever i tried the bulk import it stops there. Since the traceback stops at category ids i tried changing the -1 to 0 @last_imported_category_id = imported_category_ids.max || -1 to @last_imported_category_id = imported_category_ids.max || 0 I even tri…
