Overview:
This PR attempts to utilize
Joblib
to allowsync_all
to run streams in parallel. A new Tap class methodsync_one
was introduced to give a parallel loop a target for the streams. There is a new property calledmax_parallelism
that takes in a integer value which is passed toparallel_config
argumentn_jobs
. The default value ofmax_parallelism
isNone
. A tap will only attempt a parallel run if value is present inmax_parallelism
. The capability ofTAP_MAX_PARALLELISM_CONFIG
was added to the Tap class so a tap can be passed amax_parallelism
value via the meltano.yml.Examples:
Comments:
I need assistance with ideas on how to create pytests to cover these changes. Also if you run pytest when parallelism is enabled a lot of tests will fail, especially mapper test. The seem to only get the state message then nothing else.
