Why is Teradata Contributing to Presto?
• Why Contribute to SQL-on-Hadoop?
Advancing the UDA requires better
SQL-on-Hadoop capabilities
- Teradata is aligned around a logical
data warehouse vision
- SQL is the interaction protocol across
UDA
- SQL-on-Hadoop engine is needed to
extend QueryGrid to Hadoop query
point
Opportunities are Teradata Strengths
in this still immature space
Up-the-stack capability versus core
Hadoop
