+ Impala has done a fourth release with a third release manager.
+ 
+ Impala has begun graduation procedures: we have held a community discussion and a community vote on graduation, both unanimous. We have established our intended PMC. Next, we will draft our charter and hold a discussion on general@incubator.
+ 
+ How has the project developed since the last report?
+ 
+ Impala has removed the old unpartitioned hash and aggregation nodes, relics from years ago that were kept around for backwards compatibility: the new buffer management makes these obsolete. Code generation for decimal and timestamp types has been added to the text scanner, increasing the performance of some queries by up to 19%. More robust query plans in case of data skew have made some aggregations eight times as fast. A number of large changes are in-flight, including changes to equivalence class computation in the planner, more decimal semantics adjustments, min-max filters for Kudu, and multi-threaded metadata loading that increases the performance of some metadata operations by 8x.

+ How would you assess the podling's maturity?
