-------------------------------------

             Summary: Memory consumption fixes
                 Key: DRILL-620
                 URL: https://issues.apache.org/jira/browse/DRILL-620
             Project: Apache Drill
          Issue Type: Improvement
            Reporter: Steven Phillips
            Assignee: Steven Phillips


This jira covers work done to improve Drill's handling of memory. Specifically, this includes:

Allow trimming of buffers after the data has been written, so that unused memory can be returned to the pool.

Handle case attempts to write beyond a buffers capacity.

Handle case where a buffer allocator is unable to allocate a new buffer due to memory constraints

Dynamically adjust allocation sizes based on trends
