List containing the input mrc.SegmentObject objects.

Returns

list[mrc.SegmentObject]

List of tuples containing the output mrc.SegmentObject object from this stage.

Abstract method all derived Source classes should implement. Returns the same value as build.

Returns

mrc.SegmentObject:

The MRC node for this stage.

_build_sources(builder)[source]

Abstract method all derived Source classes should implement. Returns the same value as build.

Returns

mrc.SegmentObject:

The MRC nodes for this stage.

MRC segment for this stage.

do_propagate

Whether to propagate to build output stages, by default True.

can_build(check_ports=False)[source]

Determines if all inputs have been built allowing this node to be built.

Parameters

check_ports

Check if we can build based on the input ports, by default False.

Returns

bool

True if we can build, False otherwise.

Determines if all inputs have been built allowing this node to be built.

Parameters

check_ports

Check if we can build based on the input ports, by default False.

Returns

bool

True if we can build, False otherwise.

static cleanup_df(df, feature_columns)[source]

This function does clean up certain columns in the dataframe.

Parameters

df

Dataframe for columns cleanup.

feature_columns

Only the columns that are present in the feature columns will be preserved in the dataframe if feature columns are supplied..

Returns

df

Clean dataframe.

compute_schema(schema)[source]

Compute the schema for this stage based on the incoming schema from upstream stages.

Incoming schema and type information from upstream stages is available via the schema.input_schemas and schema.input_types properties.

Derived classes need to override this method, can set the output type(s) on schema by calling set_type for all output ports. For example a simple pass-thru stage might perform the following:

If the port types in upstream_schema are incompatible the stage should raise a RuntimeError.

static derive_features(df, feature_columns)[source]

If any features are available to be derived, can be implemented by overriding this function.

Parameters

df

A dataframe.

feature_columns

Names of columns that are need to be derived.

Returns

df

Dataframe with actual and derived columns.

static files_to_dfs_per_user(x, userid_column_name, feature_columns, userid_filter=None, repeat_count=1)[source]

After loading the input batch of CloudTrail logs into a dataframe, this method builds a dataframe for each set of userid rows in accordance with the specified filter condition.

Parameters

x

List of messages.

userid_column_name

Name of the column used for categorization.

feature_columns

Feature column names.

userid_filter

Only rows with the supplied userid are filtered.

repeat_count

Number of times the given rows should be repeated.

Returns

df_per_user

Dataframe per userid.

get_all_input_stages()[source]

Get all input stages to this stage.

Returns

list[morpheus.pipeline.pipeline.StageBase]

All input stages.

get_all_inputs()[source]

Get all input senders to this stage.

Returns

list[morpheus.pipeline.pipeline.Sender]

Returns

list[morpheus.pipeline.pipeline.StageBase]

get_all_outputs()[source]

Get all output receivers from this stage.

Returns

list[morpheus.pipeline.pipeline.Receiver]

All output receivers.

get_match_pattern(glob_split)[source]

Return a file match pattern

get_needed_columns()[source]

Stages which need to have columns inserted into the dataframe, should populate the self._needed_columns dictionary with mapping of column names to morpheus.common.TypeId. This will ensure that the columns are allocated and populated with null values.

property has_multi_input_ports: bool

Indicates if this stage has multiple input ports.

Returns

bool

True if stage has multiple input ports, False otherwise.

property has_multi_output_ports: bool

Indicates if this stage has multiple output ports.

Returns

bool

True if stage has multiple output ports, False otherwise.

property input_count: int

Return None for no max intput count

property input_ports: list[morpheus.pipeline.receiver.Receiver]

Input ports to this stage.

Returns

list[morpheus.pipeline.pipeline.Receiver]

Input ports to this stage.

property is_built: bool

Indicates if this stage has been built.

Returns

bool

True if stage is built, False otherwise.

property is_pre_built: bool

Indicates if this stage has been built.

Returns

bool

True if stage is built, False otherwise.

async join()[source]

Awaitable method that stages can implement this to perform cleanup steps when pipeline is stopped. Typically this is called after stop during a graceful shutdown, but may not be called if the pipeline is terminated on its own.

property name: str

The name of the stage. Used in logging. Each derived class should override this property with a unique name.

Returns

str

Name of a stage.

property output_ports: list[morpheus.pipeline.sender.Sender]

Output ports from this stage.

Returns

list[morpheus.pipeline.pipeline.Sender]

Output ports from this stage.

static read_file(filename, file_type)[source]

Reads a file into a dataframe.

Parameters

filename

Path to a file to read.

file_type : morpheus.common.FileTypes

What type of file to read. Leave as Auto to auto detect based on the file extension.

Returns

pandas.DataFrame

The parsed dataframe.

Raises

RuntimeError

If an unsupported file type is detected.

static repeat_df(df, repeat_count)[source]

This function iterates over the same dataframe to extending small datasets in debugging with incremental updates to the event_dt and eventTime columns.

Parameters

df

To be repeated dataframe.

repeat_count

Number of times the given dataframe should be repeated.

Returns

df_array

List of repeated dataframes.

set_needed_columns(needed_columns)[source]

Sets the columns needed to perform preallocation. This should only be called by the Pipeline at build time. The needed_columns shoudl contain the entire set of columns needed by any other stage in this segment.

async start_async()[source]

This function is called along with on_start during stage initialization. Allows stages to utilize the asyncio loop if needed.

stop()[source]

Stages can implement this to perform cleanup steps when pipeline is stopped.

supports_cpp_node()[source]

Specifies whether this Stage is capable of creating C++ nodes. During the build phase, this value will be combined with CppConfig.get_should_use_cpp() to determine whether or not a C++ node is created. This is an instance method to allow runtime decisions and derived classes to override base implementations.

property unique_name: str

Unique name of stage. Generated by appending stage id to stage name.

Returns

str

Unique name of stage.
