📝 Walkthrough

Walkthrough

The Jira extractor now uses JiraCloud, retrieves issues with project-specific JQL, records issue keys, and exposes an issue_status_changelog resource. The resource bulk-fetches status histories and yields a typed Arrow table with UTC timestamps.

Changes

Jira extraction

Layer / File(s) Summary
Jira client and resource registration
elt-pipelines/facility_ops/ingest/computing/jira/jira.py
The extractor uses JiraCloud without the configurable cloud flag. It registers the issue and issue_status_changelog resources.
Issue retrieval and key collection
elt-pipelines/facility_ops/ingest/computing/jira/jira.py
Issue retrieval uses project-specific JQL ordered by issue key and records each extracted issue key.
Status changelog extraction
elt-pipelines/facility_ops/ingest/computing/jira/jira.py
The extractor bulk-fetches status changes, maps issue IDs to issue keys, converts millisecond timestamps to UTC datetimes, and yields a typed Arrow table.

Merge Risk: 🟠 High · up to 87019

The new changelog output can include status changes for stale issues and omit changes for every issue except the last one processed, resulting in inaccurate or incomplete Jira data. These correctness problems should be fixed before merging.

In `@elt-pipelines/facility_ops/ingest/computing/jira/jira.py`:
- Around line 39-43: Move issueKeys initialization into Extract.__init__ so each
Extract instance has its own list, and clear it at the start of each
issue-extraction operation to prevent keys from a prior extraction being reused.
- Around line 53-59: Update the extract_issue_status_changelog method signature
to accept an optional Watermark parameter, matching the extractor contract used
by ResourceProperties; leave its existing extraction behavior unchanged.
- Around line 118-125: Update the changelog retrieval around self.issueKeys and
get_bulk_changelogs to split issue keys into batches of at most 1,000, skip
empty batches, and follow each response’s nextPageToken until all pages are
fetched. Aggregate the returned issueChangeLogs from every batch and page before
constructing issue_changelogs.
- Around line 137-143: Update the issue retrieval flow to retain an
ID-to-issue-key mapping, then use the mapping when assigning issue_key in the
changelog append within get_bulk_changelogs processing. Preserve the existing
change fields and ensure the internal issueId is converted to the corresponding
Jira key before writing each record.
- Around line 131-134: Update the conversion of
changeHistory[IssueField.Created] in the changelog processing flow to parse its
ISO 8601 date-time string using DATE_FORMAT_STRING or an equivalent ISO 8601
parser, rather than dividing it as a numeric timestamp; preserve the resulting
UTC-aware datetime in changed_at.

This is getting there and the structure is all good.

There are a couple of points to address around pagination and access the appropriate fields.

Just a note about our discovery here. No action needed.

Switching to JiraCloud to access the get_bulk_changelogs meant that get_all_project_issues was no longer accessible. The code just did this anyway...

Reset _issue_keys before issue extraction.

_issue_keys remains populated when the same Extract instance performs a second issue extraction. The changelog resource can then request and write status changes for keys outside the current extraction.
