  * Allow in predicate support
  * Improve significantly scan performance
  * Add INSERT OVERWRITE statement
  * Add CREATE TABLE statement

Apache Tajo is an effort undergoing incubation at The Apache Software
Foundation (ASF) sponsored by the Apache Incubator PMC. Incubation is
required of all newly accepted projects until a further review
indicates that the infrastructure, communications, and decision making
process have stabilized in a manner consistent with other successful
ASF projects. While incubation status is not necessarily a reflection
of the completeness or stability of the code, it does indicate that
the project has yet to be fully endorsed by the ASF.
