FLP Suite Workflow Configuration

The ControlWorkflows repository hosts the configuration tree for AliECS workflow templates (WFT) and task templates (TT).

Available workflow templates:

• qc-postprocessing - QualityControl post-processing workflow
• readout-dataflow - Main FLP workflow
• readout-qc - QualityControl workflow with Readout as source
• readout-stfb-qc - QualityControl workflow with StfBuilder as source

Notes on input data types

This is mostly relevant to coconut users and users who edit or produce their own WFTs and TTs.

All AliECS variables are strings. Some workflow templates can choose to treat a string variable as a JSON payload, with built in functions such as ToJson/FromJson, but they are always provided as strings by the user, and stored as strings in the key-value map.

Boolean values are also stored as strings, i.e. "true" and "false". This is because they can be read in as template expressions, i.e. strings, which are then processed into boolean values during workflow loading.

Common workflow variables

All variables except hosts are optional.

Variable	Description	Example	Default
hosts	JSON-formatted list of hosts to control the scale of certain workflows	["myhost1","myhost2"]	[]
readout_cfg_uri	URI of a Readout configuration payload	file:/home/flp/readout.cfg	depends on WFT
user	Name of the Linux user that should run all tasks	root	flp
