Flux built-in transformation functions

Built-in aggregate transformations

Flux’s aggregate transformations take values from an input table and aggregate them in some way. Output tables contain a single row with the aggregated value.

Built-in selector functions

Flux’s built-in selector functions return one or more records based on function logic.

Built-in type conversion functions

Flux’s built-in built-in type conversion functions convert columns of the input table into a specific data type.

Stream and table functions

Use stream and table functions to extract a table from a stream of tables and access its columns and records.
