Decrease write-block-size


#1

Hello!

I want to change write-block-size from 4M to 1M.

In FAQ: * If decreasing the write-block-size it is necessary to first delete all the records that are bigger than the new lower write-block-size and also zeroize the disks which will require to wait for migrations to complete between each node.

  1. So how to know which records have bigger than the new lower write-block-size? Which command in AQL is using for it?
  2. How to delete this record? Which command in AQL is using for it?

You can do a scan with a predicate filter and delete records over a certain size.
