  Although they are a diverse group of developers, what most of core developers are in South
Korea is a risk. This is because their offline activities are limited due to their location.
Since we surely recognize this risk, we will write more complete documents and presentation
materials in order to disseminate Tajo's internal and users guide. In addition, to mitigate
this risk we will be eager to recruit additional committers around the world.
  
  == Reliance on Salaried Developers ==
- It is expected that Tajo development will occur on both salaried time and on volunteer time.
Hyunsik and Jihoon belong to Database lab., Korea Univ. They will be paid by the lab to contribute
Tajo for years. Jin Ho and Sangwook are paid by their employer to contribute to this project.
Eli and Henry will contribute to this project on volunteer time. In addition, we will be eager
to recruit additional committers including salaried and non-salaried developers.

  == Relationships with Other Apache Products ==
  Tajo has some overlapping function with Apache Incubator Drill. However, Tajo is more mature
than Drill. In addition, there are some significant differences. Drill is a distributed system
specialized for low-latency query processing by using column operations and intermediate data
streaming. Drill has very simple query optimizer. However, some queries including big-big
table join and sort are not available in that manner. Drill will support some of query types.
