This file lists all the Kafka topics currently used by sandcrawler (and
fatcat).
NOTE: should use `.` or `_` in topic names, but not both. We chose to use `.`
ENV below is one of `prod` or `qa`.
## Topic List
All topics should default to `snappy` compression on-disk, and indefinite
retention (on both a size and time basis).
sandcrawler-ENV.grobid-output-pg
=> output of GROBID processing using grobid_tool.py
=> schema is sandcrawler-db style JSON: TEI-XML as a field
=> expected to be large; 12 partitions
=> use GZIP compression (worth the overhead)
=> key is sha1hex of PDF; enable key compaction
sandcrawler-ENV.ungrobided-pg
=> PDF files in IA needing GROBID processing
=> schema is sandcrawler-db style JSON. Can be either `cdx` or `petabox` object
=> fewer partitions with batch mode, but still a bunch (24?)
=> key is sha1hex of PDF. enable time compaction (6 months?)
sandcrawler-ENV.ingest-file-requests
=> ingest requests from multiple sources; mostly continuous or pseudo-interactive
=> schema is JSON; see ingest proposal for fields. small objects.
=> fewer partitions with batch mode, but still a bunch (24)
=> can't think of a good key, so none. enable time compaction (3-6 months?)
sandcrawler-ENV.ingest-file-requests-bulk
=> ingest requests from bulk crawl sources; background processing
=> same as ingest-file-requests
sandcrawler-ENV.ingest-file-results
=> ingest requests from multiple sources
=> schema is JSON; see ingest proposal for fields. small objects.
=> 6 partitions
=> can't think of a good key, so none; no compaction
fatcat-ENV.api-crossref
fatcat-ENV.api-datacite
=> all new and updated DOIs (regardless of type)
=> full raw crossref/datacite API objects (JSON)
=> key: lower-case DOI
=> ~1TB capacity; 8x crossref partitions, 4x datacite
=> key compaction possible
fatcat-ENV.api-crossref-state
fatcat-ENV.api-datacite-state
fatcat-ENV.oaipmh-pubmed-state
fatcat-ENV.oaipmh-arxiv-state
fatcat-ENV.oaipmh-doaj-journals-state (DISABLED)
fatcat-ENV.oaipmh-doaj-articles-state (DISABLED)
=> serialized harvester state for ingesters
=> custom JSON
=> key: timespan? nothing to start
=> 1x partitions; time/space limit Ok
fatcat-ENV.changelog
=> small-ish objects (not fully expanded/hydrated)
=> single partition
=> key: could be changelog index (integer, as string)
fatcat-ENV.release-updates-v03
=> contains "fully" expanded JSON objects
=> v03 is newer v0.3.0 API schema (backwards incompatible)
=> key: fcid
=> 8x partitions
fatcat-ENV.work-updates
=> key: fcid
=> 8x partitions
fatcat-ENV.container-updates
=> key: fcid
=> 4x partitions
fatcat-ENV.file-updates
=> key: fcid
=> 4x partitions
### Deprecated/Unused Topics
sandcrawler-ENV.ungrobided
=> PDF files in IA needing GROBID processing
=> 50x partitions (huge! for worker parallelism)
=> key: "sha1:<base32>"
sandcrawler-ENV.grobid-output
=> output of GROBID processing (from pdf-ungrobided feed)
=> could get big; 16x partitions (to distribute data)
=> use GZIP compression (worth the overhead)
=> key: "sha1:<base32>"; could compact
fatcat-ENV.oaipmh-pubmed
fatcat-ENV.oaipmh-arxiv
fatcat-ENV.oaipmh-doaj-journals (DISABLED)
fatcat-ENV.oaipmh-doaj-articles (DISABLED)
=> OAI-PMH harvester output
=> full XML resource output (just the <<record> part?)
=> key: identifier
=> ~1TB capacity; 4x-8x partitions
=> key compaction possible
## Create fatcat QA topics
If you run these commands for an existing topic, you'll get something like
`Error while executing topic command : Topic 'fatcat-qa.changelog' already
exists`; this seems safe, and the settings won't be over-ridden.
