             Summary: [CPP]: Reduce buffer allocations (mallocs) on critical path
                 Key: PARQUET-909
                 URL: https://issues.apache.org/jira/browse/PARQUET-909
             Project: Parquet
          Issue Type: Improvement
            Reporter: Deepak Majeti
            Assignee: Deepak Majeti


The current implementation allocates and frees memory many times on the critical path. The scope of this JIRA is to reuse buffers where possible.
On production systems, too many mallocs/frees can impact performance.
