I am somewhat new to Accumulo and was doing some experimentation on consequences for using large numbers of authorizations. I found that a user with a large set of authorizations would take a great deal of time to perform a scan. I tested at various increments up to 100,000 authorizations. At that point, it would take at least 25 seconds to perform the scan, even if the table was newly created with no rows. Performing a scan with a small subset of authorizations is equivalent to performing a query with a user that only has a small number of authorizations. I attempted to find the place in the code where whatever is being done, because I wanted to understand what caused this, but I wasn't able to track down the exact class. Any chance I could get an explanation or pointed in the right direction? Thanks!
