DatasetProfile

public DatasetProfile(@NonNull
                      @NonNull java.lang.String sessionId,
                      @NonNull
                      @NonNull java.time.Instant sessionTimestamp,

                      @NonNull java.util.Map<java.lang.String,ColumnProfile> columns)

DEVELOPER API. DO NOT USE DIRECTLY

Parameters:

sessionId - dataset name

sessionTimestamp - the timestamp for the current profiling session

dataTimestamp - the timestamp for the dataset. Used to aggregate across different cadences

tags - tags of the dataset

columns - the columns that we're copying over. Note that the source of columns should stop using these column objects as they will back this DatasetProfile instead

DatasetProfile

public DatasetProfile(@NonNull
                      @NonNull java.lang.String sessionId,
                      @NonNull
                      @NonNull java.time.Instant sessionTimestamp,

                      @NonNull java.util.Map<java.lang.String,java.lang.String> tags)

Create a new Dataset profile

Parameters:

sessionId - the name of the dataset profile

sessionTimestamp - the timestamp for this run

tags - the tags to track the dataset with

merge

public DatasetProfile merge(@NonNull
                            @NonNull DatasetProfile other)

Merge the data of another DatasetProfile into this one.

We will only retain the shared tags and share metadata. The timestamps are copied over from this dataset. It is the responsibility of the user to ensure that the two datasets are matched on important grouping information

Parameters:

other - a DatasetProfile

Returns:

a merged DatasetProfile with summed up columns
