  3. abstract def summarize(df: Any, precise: Boolean = false): Unit

    Summarize a Spark DataFrame and visualize the statistics to get quick insights.

    Summarize a Spark DataFrame and visualize the statistics to get quick insights.

    Example:

    dbutils.data.summarize(df, precise=false)
    df

    The dataframe to summarize. Streaming dataframes are not supported.

    precise

    If false, percentiles, distinct item counts, and frequent item counts will be computed approximately to reduce the run time. If true, distinct item counts and frequent item counts will be computed exactly, and percentiles will be computed with high precision.

    returns

    visualization of the computed summmary statistics. Summarize a DataFrame and visualize the statistics to get quick insights.
