            Bug ID: 2021
           Summary: Evolve storage cursor API
           Product: Thermostat
           Version: hg
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P5
         Component: Thermostat
          Assignee: unassigned at icedtea.classpath.org
          Reporter: sgehwolf at redhat.com
                CC: thermostat at icedtea.classpath.org

The current Cursor[1] storage API is insufficient. There is currently no way to
use the current Cursor API and fetch results in a reasonable way. It's
currently all-or-nothing (or at least implementation dependent). We should at
least add the following API in order to be able to limit result sets and be
able to skip over values:

Cursor.limit(int);
Cursor.skip(int);

Preferably also add:

Cursor.setBatchSize(int);
