"""Setup the pipelines according to config.
The configuration is supported as follows:
Decoupled: the source and sink configuration are separately
specified before being linked together. This allows source-
specific configuration, such as resource discovery, to be
kept focused only on the fine-grained source while avoiding
the necessity for wide duplication of sink-related config.
The configuration is provided in the form of separate lists
of dictionaries defining sources and sinks, for example:
{"sources": [{"name": source_1,
"interval": interval_time,
"meters" : ["meter_1", "meter_2"],
"resources": ["resource_uri1", "resource_uri2"],
"sinks" : ["sink_1", "sink_2"]
},
{"name": source_2,
"interval": interval_time,
"meters" : ["meter_3"],
"sinks" : ["sink_2"]
},
],
"sinks": [{"name": sink_1,
"transformers": [
{"name": "Transformer_1",
"parameters": {"p1": "value"}},
{"name": "Transformer_2",
"parameters": {"p1": "value"}},
],
"publishers": ["publisher_1", "publisher_2"]
},
{"name": sink_2,
"publishers": ["publisher_3"]
},
]
}
The interval determines the cadence of sample injection into
the pipeline where samples are produced under the direct control
of an agent, i.e. via a polling cycle as opposed to incoming
notifications.
Valid meter format is '*', '!meter_name', or 'meter_name'.
'*' is wildcard symbol means any meters; '!meter_name' means
"meter_name" will be excluded; 'meter_name' means 'meter_name'
will be included.
The 'meter_name" is Sample name field. For meter names with
variable like "instance:m1.tiny", it's "instance:*".
