Motivation

...

• qc-files can be left at their original location (no copy required)

• file-system sharing is not required, tcp/ip is enough (so that if Oppy needs to send some qc-metrics from Mars it would be able to do so)

• no need to create new customized tables for each application - everything (vvp, smartessmartseq, etc) would be transformed into JSON and stored in METRICS table

• resilience - at most imperfect data would lead to individual fields showing up as blank

• straightforward JSON extraction in Tableau by using Oracle’s JSON constructs

...

• url=https://analytics.broadinstitute.org/Metrics?type=vvp
  where the file should be sent to

• filepathRegex=(.*)/(.*AspAllOutputQC.csv)
  which file-names should be picked

• outer_columns=field1=$1,field2=$2,field3=XYZ
  parse fields out of the filepathRegex and injects them in the JSON (useful when bits of data is encoded in the filename)

• dryrun=true
  run all the delta capturing and regex-parsing and show the data without actually pushing the file

• delta=<delta specification>
  specifies ”how” files to be picked

  • pick 1 (or multiple) specific files
    delta=FILES_CSV /seq/tableau_files/VVPVolumeQC/20221205_RACK_QC_083303_AspAllOutputQC.csv

  • pick files timestamped between this and that timestamp
    delta=FILES IN FOLDER /seq/tableau_files/VVPVolumeQC TIMESTAMPED BETWEEN 2019-10-19 13:11:46 AND 2019-10-19 13:11:46

  • pick files timestamped in last 10 hours
    delta=FILES IN FOLDER /seq/tableau_files/VVPVolumeQC TIMESTAMPED BETWEEN -10h AND NOW

  • pick files timestamped between persisted-in-file-timestamp and now (production setup)
    delta=FILES IN FOLDER /seq/tableau_files/VVPVolumeQC TIMESTAMPED BETWEEN /seq/tableau_files/VVPVolumeQC/VVP_etl_timestamp.txt AND NOW
    The file merely contains a timestamp(2019-10-19 13:11:46) and should be created manually
