@sugarcube/plugin-workflow

A collection of plugins that support investigation workflows.

Installation

npm install --save @sugarcube/plugin-workflow

Plugins

workflow_merge

Merge additional fields into every unit of the data pipeline. Additional fields are specified using the workflow_merge query source. The additional fields have to be provided as a valid JSON object.

Example:

sugarcube -p test_generate,workflow_merge,tap_printf \
          -Q workflow_merge:'{"hello": "world"}'

workflow_merge_query

Merge any fields from the query object into units acquired for this query. This allows to annotate data with data stored alongside the query sources. This plugin will skip the merge if the unit already has a value set for this field. This behavior can be changed by setting the --overflow.overwrite_query_merge flag.

Example:

sugarcube -p sheets_queries,youtube_video,workflow_merge_query \
          --google.query_fields last_access,cid.incident_code,notes \
          --workflow.merge_query_fields cid.incident_code,notes

The above example fetches queries from a Google spreadsheet and along the query type and term fetches the fields last_access, cid.incident_code and notes. The cid.incident_code and notes fields are merged into the data units found for this type and term.

Configuration:

  • workflow.merge_query_fields: An array of field names that should be merged into the unit.
  • workflow.overwrite_query_merge: Set to true to merge fields even if a value is already set on the unit for this field. Defaults to false.

workflow_multiplex

Break all queries into batches with a size configured by workflow.multiplex_size and run the remainder of the pipeline once for each batch. This allows to break the whole pipeline into smaller executions. This helps to deal with data processes that would yield a huge number of observations.

Example:

sugarcube -p workflow_multiplex,youtube_channel,media_youtubedl \
          -q queries.json

The above example will run the pipeline `youtube_channel,media_youtubedl** once for every query separately.

Configuration:

  • workflow.multiplex_size: Set the size of each batch of queries. Defaults to 1.
  • workflow.multiplex_continue_on_error: As a default, if any batch throws an error, the execution stops. Using this flag continues execution, even if an individual batch throws an error.

Example:

sugarcube -p workflow_multiplex,youtube_channel,media_youtubedl \
          --workflow.multiplex_size 10 \
          --workflow.multiplex_continue_on_error \
          -q queries.json

workflow_multiplex_end

This plugin acts as a stopper for `workflow_multiplex** to signal where the multiplexing should end. It will then resume the remainder of the pipeline as a single run. Not that the data envelope is not carried over into the remainder pipeline. Only the queries, cache and stats are preserved.

Example:

sugarcube -p workflow_multiplex,youtube_channel,media_youtubedl,workflow_multiplex_end,mail_report_stats \
          -q queries.json

The above example will multiplex the youtube_channel,media_youtubedl bits into batches of one query per batch. After all batches finished, the pipeline resumes all plugins after workflow_multiplex_end. In this case the mail_report_stats plugin is called a single time.

workflow_omit plugin

Omit individual fields from all units. The fields can be specified on the command line using a comma separated string or as an array in the JSON config file.

Configuration:

  • workflow.omit_fields: Specify the name of the fields to omit.

Example:

sugarcube -p workflow_omit --workflow.omit_fields a,b,c

workflow_pick plugin

Pick the list of attributes from every unit and drop the rest.

Configuration:

  • workflow.pick_fields: Specify the name of the fields to pick.

Example:

sugarcube -p workflow_pick --workflow.pick_fields a,b,c
