This pipeline is collecting results from the sub-ordinate pipelines (bibliographic, non-bibliographic, fulltext, orcid claims, metrics). It also updates production data stores: SOLR, Metrics DB and link resolver.
- update-record: input from the 'other' pipelines is collected here
- index-record: internal queue, it forwards data to solr/metrics
- delete-record: removes from solr/metrics db
- rebuild-index: used during weekly rebuild of solr
- index-solr: internal queue of records to send to solr
- index-metrics: internal queue of records to send to metrics on aws
- index-data-links-resolver: internal queue of records to send to data links resolver

The pipeline will NOT send anything to SOLR/Metrics DB/data links resolver by default. You should trigger the update using a cronjob. There are two important modes:
- normal mode (`python run.py -r`): will discover all updates that happened since the last invocation
of the normal mode and will send them to the `index-records` queue; the parameter force will be set to False; hence only documents that have both metadata, orcid claims, and non-bib data will get sent to solr
- pushy mode (`python run.py -r -f`) will discover all updates since the last invocation of the 'pushy' mode; and will send them to `index-records` queue and set force=True; this will force the worker to submit data to solr immediately (so effectively, this means any update to a record triggers push). Regardless, we always wait till we have bibliographic metadata.
It is imperative that both modes of operation be used together in the 24h cycle. The normal mode will ignore some (many)
records - so you must call the pushy mode at least at the end of the quiet period. The suggested schedule is the following (all times UTC):
00:00-05:00 | normal mode, invoked every 5 mins 05:00-06:00 | catch updates, invoke forced mode 06:01-17:00 | --- do nothing, solr replication is not happening 17:01-22:00 | normal mode, invoked every 5 mins 22:01-23:59 | forced mode, catch updates
Always write unittests (even: always write unitests first!). Travis will run automatically. On your desktop run:
`$ py.test`
