- `ALTER UPDATE` for batch changing the data with approach similar to `ALTER DELETE`
- Protobuf and Parquet input and output formats
- Improved compatibility with Tableau and other BI tools
## Q4 2018
- JOIN syntax compatible with SQL standard:
- Mutliple `JOIN`s in single `SELECT`

- Support table reference instead of subquery
- JOIN execution improvements:
- Distributed join not limited by memory
- Predicate pushdown through join
- Resource pools for more precise distribution of cluster capacity between users
