Motivation

There have been situations where end users need to review a sample, check relevant metrics and trigger a specific Action - for example "for a given sample, IF RapidQC has completed AND LOD>0 THEN submit "FinalAggregation" request in Pipeline's JMS queue". All of these actions to be done/initiated from within Tableau. Beyond visualization, Tableau can't do much else in terms of maintaining a "workflow" in DB, talking to external web-services like JMS and so on. That's why these job is being outsourced to our "SampleAnalyticsWorkflow" web-service - it's written in Scala so there is virtually no limit what tasks it can do for you. Tableau utilize it's UrlAction gadget to make a URL call to SAW service when appropriate.

1 encodes RequestFinalAggregation, 2 encodes RequestTopOff and so on
USER_NAMEVARCHAR2who triggered this action/transition
PARAMSVARCHAR2This is a free text where Tableau developers can store additional info re this transition which later can be used. Usually it's semicolon-separated-list-of-key=value-pairs
TIMESTAMPDATEwhen this action was triggered
IS_LATESTNUMBERBoolean (1 or 0), Is this the latest transition a given (PDO, PDO_SAMPLE, DATA_TYPE) has gone through. Every time new transition is recorded it comes with IS_LATEST=1 whereas previous latest transition is reset IS_LATEST=0
IP_ADDRESSVARCHAR2where (which IP) this request came from

...

  • requestType is the text-representation of this request (RequestFinalAggregation, RequestTopOff, etc)
  • each individual item is a quintuple representing a single sample like this pdo:pdo_sample:data_type:user_name:parameters (greens are optional)

...

RequestFinalAggregation is the only request which also sends message to Pipeline JMS queue. This is done by SAW in 2 steps

...

  1. JOIN cognos.slxre_readgroup_metadata ON (pdo, pdo_sample, data_type) and lookup (research_project_id,collaborator_sample_id) for a given sample

...

  1. send JSON message to appropriate JMS queue

Pipeline is picking up messages from this queue.

...

  1. take user_name out of items (see authentication above)
  2. take out PDO-, SM- prefixes resp from PDO, PDO_SAMPLE. SAW will automatically add them back as needed.
  3. parameters which are pertinent to all samples (for example source=RQC) should be moved to standalone extra_info parameter. SAW will disperse it to PARAMS column of all samples involved.
  4. regarding parameters which are sample-specific (for example xShort=123;yLong=567)
    1. move all keys to standalone params_fields url-parameter as colon-separated-list-of-keys
    2. in the items/samples parameter leave only the values as semicolon-separated-list-of-values. SAW will pair back keys/values accordingly and insert it into PARAMS column.
  5. In item's data_type, encode Exome with E (resp.WGS with W)
