Class
Description
Base class defining a function invocation.
The base class for function definitions.
Applies an aggregate or selector function (any function with a column parameter) to fixed windows of time.
Constructs a table from an array of records.
The column restrictions.
The columns() function lists the column labels of input tables.
Counts the number of results.
Covariance is an aggregate operation.
Cumulative sum computes a running sum for non null records in the table.
Computes the time based difference between subsequent non null records.
Difference computes the difference between subsequent non null records.
Distinct produces the unique values for a given column.
Drop will exclude specified columns from a table.
Duplicate will duplicate a specified column in a table.
Marker interface for Expressions.
The custom Flux expression.
A container holding a list of
Expressions.Replaces all null values in input tables with a non-null value.
Filters the results using an expression.
Returns the first result of the query.
Flux - Data Scripting Language.
An expression to encapsulate an arbitrary expression.
From produces a stream of tables from the specified bucket.
The function properties.
Groups results by a user-specified set of tags.
Marker interface indicating existence of potential imports.
For each aggregate column, it outputs the area under the curve of non null records.
Inserts rows at regular intervals using linear interpolation to determine values for inserted rows.
Marker interface for variable assignments.
Join two time series together on time and the list of on keys.
Keep is the inverse of drop.
Returns the last result of the query.
Restricts the number of rows returned in the results.
Applies a function to each row of the table.
Returns the max value within the results.
Returns the mean of the within the results.
Returns the min value within the results.
Pivot collects values stored vertically (column-wise) in a table and aligns them horizontally (row-wise)
into logical sets.
Quantile is both an aggregate operation and a selector operation depending on selected options.
Methods for computation.
Filters the results by time boundaries.
Reduce aggregates records in each table according to the reducer.
Rename will rename specified columns in a table.
Sample values from a table.
Assigns a static value to each record.
Skew of the results.
Sorts the results by the specified columns Default sort is ascending.
Difference between min and max values.
Standard Deviation of the results.
Sum of the results.
Tail caps the number of records in output tables to a fixed size n.
Flux duration literal -
spec.
Shift add a fixed duration to time columns.
Convert a value to a bool.
Convert a value to a duration.
Convert a value to a float.
The To operation takes data from a stream and writes it to a bucket.
Convert a value to a int.
Convert a value to a string.
Convert a value to a time.
Convert a value to a duration.
Truncates all input time values in the _time to a specified unit..
Merges two or more input streams into a single output stream..
Hold the variable name and expression of an assignment.
Groups the results by a given time range.
Yield a query results to yielded results.
