Detailed Description

A set of output parameters for getRecordsByColumn(const GetRecordsByColumnRequest&) const.

For a given table, retrieves the values from the requested column(s). Maps of column name to the array of values as well as the column data type are returned. This endpoint supports pagination with the offset and limit parameters.

Window functions, which can perform operations like moving averages, are available through this endpoint as well as createProjection(const CreateProjectionRequest&) const.

When using pagination, if the table (or the underlying table in the case of a view) is modified (records are inserted, updated, or deleted) during a call to the endpoint, the records or values retrieved may differ between calls based on the type of the update, e.g., the contiguity across pages cannot be relied upon.

The response is returned as a dynamic schema. For details see: dynamic schemas documentation.
