My bot updates reports at https://www.wikidata.org/wiki/Wikidata:Database_reports/Constraint_violations
I want to move the bot to Toolforge because my host has insufficient amount of RAM for growing Wikidata DB. Now bot uses ~ 64 GB of virtual memory. But my host has only 32 GB of RAM. So performance of the bot became too bad.
Bot is written on C++, it loads the latest Wikidata dump into memory and uses this data for the reports generation. I already done multiple optimizations of memory usage.
