The wvlet, pronounced as weave-let, is a new query language for all types of data, including SQL engines (DBMSs), local files, programing language objects, etc.

wvlet queries (.wv) are designed to be:

• Composable. wvlet queries can be defined as functions, which can be reused for other data processing.
• Reproducible. You can build a reproducible data procesing pipeline with time-window based incremental processing.

wvlet queries will be compiled into SQL queries and code for target programming languages.
