I have a large HBase table (~10 TB) that has an existing key structure. Based on some recent analysis, the key structure is causing performance problems for our current query load. I would like to re-write the table with a new key structure that performs substantially better.
What is the best way to go about re-writing this table? Since they key structure will change, it will affect locality, so all the data will have to move to a new location. If anyone can point to examples of code that does something like this, that would be very helpful. Thanks, Marcell
