Invoking TableOperations.deleteRows 400 times to delete different ranges from a single large table (about 5 TB of data stored in 9.52K tablets and 544.42K entries) runs very slowly and causes timeout errors for other processes trying to write simultaneously into the same table. Looking into the "Recent Logs" of the monitor I can see warning "Not balancing due to 1 outstanding migrations." reported 95600 times!
What's the best way to troubleshoot this? Thanks
