Components

1. Jira Webhook Configuration

Location: https://your-org.atlassian.net/plugins/servlet/webhooks

Setting	Value
URL	https://your-instance.example.com/webhooks/jira
Secret	Same as JIRA_WEBHOOK_SECRET in server .env
JQL Filter	project = "Your Project"

Subscribed Events:

• Issue: created, updated, deleted
• Comment: created, updated
• Attachment: created
• Issue link: created

2. Webhook Receiver

File: webapp/jira_webhook.py

Flask blueprint that handles incoming webhooks:

@jira_bp.route("/jira", methods=["POST"])
def receive_jira_webhook():
    # 1. Verify HMAC signature
    # 2. Parse JSON payload
    # 3. Log event to webhook_events/
    # 4. Call jira_service.process_webhook_event()

Endpoints:

Endpoint	Method	Description
/webhooks/jira	POST	Receive webhooks from Jira
/webhooks/jira/health	GET	Health check, shows config status
/webhooks/jira/test	POST	Manual issue fetch (debug mode only)

3. Jira Service

File: webapp/jira_service.py

Handles Jira API communication and data persistence:

class JiraService:
    def fetch_issue(issue_key) -> dict
        # GET /rest/api/3/issue/{key}?expand=renderedFields,changelog&fields=*all

    def fetch_sla_fields(issue_key) -> dict | None
        # GET via cloud API with JSM service account
        # Returns SLA fields (first_response_time, time_to_resolution)

    def save_issue(issue_data) -> Path
        # 1. Fetch remote links
        # 2. Overlay SLA fields from service account
        # 3. Save to /data/src_data/raw/jira/issues/{key}.json
        # 4. Download attachments

    def download_attachment(attachment, issue_key) -> Path
        # GET attachment content URL with auth
        # Save to attachments/{issue_key}/{id}_{filename}

Why fetch after webhook?

• Webhook payload contains minimal data
• Full issue data requires API call with fields=*all
• Ensures we have complete, consistent data

Why two API tokens?

• Personal token fetches all fields except SLA (lacks JSM Agent licence)
• JSM service account token fetches SLA fields via Atlassian Cloud API
• SLA data is overlayed into the issue JSON before saving

4. Data Transformation

Two transformation modes are available:

4a. Incremental Transform (Real-Time)

File: src/incremental_jira_transform.py

Called automatically by webhook handler after saving issue JSON and attachments. Updates only the affected monthly Parquet file.

# Called from jira_service.py after save_issue()
from src.incremental_jira_transform import transform_single_issue

transform_single_issue(
    issue_key="SUPPORT-1234",
    deleted=False,  # or True for deletion events
)

How it works:

1. Loads the saved JSON for the issue
2. Determines the month from created_at date
3. Loads existing Parquet for that month (if any)
4. Upserts issue data (removes old, adds new)
5. Saves updated Parquet
6. Copies to distribution directory for rsync

Benefits:

• Data available within seconds of Jira change
• Only updates one monthly file (~50-100KB)
• Rsync transfers only changed files

4b. Batch Transform (Initial Load / Recovery)

File: src/jira_transform.py

Used for initial historical load or to rebuild all Parquet from raw JSON.

python src/jira_transform.py \
    --raw-dir /data/src_data/raw/jira \
    --output-dir /data/src_data/parquet/jira \
    --attachments-dir /data/src_data/raw/jira/attachments

Common transformations (both modes):

• Extracts plain text from ADF (Atlassian Document Format)
• Maps custom field IDs to human-readable names
• Normalizes nested structures into flat tables
• Links attachments to local file paths
• Enforces explicit PyArrow schema for consistent types across months

5. Data Distribution

Analysts sync data via rsync (same as other data):

bash server/scripts/sync_data.sh

This syncs:

• server/parquet/jira/ - Parquet tables (issues, comments, attachments metadata, changelog, issuelinks, remote_links)

For attachment files, see Attachment Access section below.

Data Flow Timeline (Real-Time)

T+0ms    Jira: Issue updated
T+50ms   Jira: Webhook POST to our server
T+100ms  Server: Verify signature, log event
T+150ms  Server: GET /rest/api/3/issue/{key} from Jira API
T+400ms  Server: GET SLA fields via JSM service account (cloud API)
T+500ms  Server: Save JSON (with SLA overlay) to raw/jira/issues/
T+600ms  Server: Download attachments (parallel)
T+800ms  Server: Incremental transform → update monthly Parquet
T+900ms  Server: Copy to distribution directory
T+1000ms Server: Return 200 OK to Jira

(analyst sync - any time)
T+Xsec   Analyst: bash sync_data.sh
T+Xsec   Analyst: rsync downloads only changed monthly file (~50KB)
T+Xsec   Analyst: Query with DuckDB - sees latest data

Key improvement: Incremental transform runs immediately after webhook processing, so data is available for sync within seconds of the Jira change.

Monthly Partitioning Benefits:

• Efficient rsync: only changed months are transferred
• Better performance: smaller files for ~15,000 total tickets
• Incremental updates: new months don't rewrite old data

Monitoring

Security

Layer	Protection
Webhook	HMAC-SHA256 signature verification
API Auth	HTTP Basic Auth (email + API token)
Storage	Server directories with data-ops group permissions
Transport	HTTPS only (Let's Encrypt certificate)

Webhook Signature Verification:

expected = hmac.new(
    secret.encode('utf-8'),
    request.get_data(),
    hashlib.sha256
).hexdigest()

if not hmac.compare_digest(signature, expected):
    abort(401)

Troubleshooting

Webhook not received

1. Check Jira webhook is enabled and URL is correct
2. Verify JQL filter matches the issue's project
3. Check server firewall allows HTTPS from Atlassian IPs

Signature verification fails

1. Verify JIRA_WEBHOOK_SECRET matches in both Jira and server .env
2. Check for trailing whitespace in secret
3. Restart webapp after changing .env

Attachments not downloading

1. Check JIRA_API_TOKEN is valid
2. Verify API token has read access to attachments
3. Check disk space on /data partition
4. Large attachments (>50MB) are skipped by design

Missing data in Parquet

1. Run transformation manually:

   python src/jira_transform.py \
       --raw-dir /data/src_data/raw/jira \
       --output-dir /data/src_data/parquet/jira \
       --attachments-dir /data/src_data/raw/jira/attachments
   

2. Check for errors in transformation output
3. Verify raw JSON files exist in raw/jira/issues/
4. Note: Output files are partitioned by month (e.g., issues/2026-01.parquet)

Schema Reference

See docs/jira_schema.md for detailed table schemas and example queries.

Historical Backfill

For initial setup or recovery, use the backfill script to download all historical issues.

File: scripts/jira_backfill.py

# Download all SUPPORT tickets (idempotent, skips existing)
python scripts/jira_backfill.py --parallel 4

# Environment variables required:
JIRA_DOMAIN=your-org.atlassian.net
JIRA_EMAIL=integration-user@your-domain.com
JIRA_API_TOKEN=<API token>
JIRA_DATA_DIR=/data/src_data/raw/jira  # optional, default path

Features:

• Uses new Jira Cloud API (POST /rest/api/3/search/jql with nextPageToken)
• Parallel downloads (configurable workers)
• Downloads all attachments
• Idempotent - skips already downloaded issues
• Handles rate limiting gracefully

SLA backfill (separate script, uses JSM service account):

File: scripts/jira_backfill_sla.py

# Fetch SLA fields for all issues (uses JIRA_SLA_* env vars)
python scripts/jira_backfill_sla.py --parallel 8

# Dry run (count files needing update):
python scripts/jira_backfill_sla.py --dry-run

The personal API token lacks JSM Agent licence needed for SLA fields. This script uses the JSM service account via the Atlassian Cloud API (api.atlassian.com) to fetch and embed SLA data into existing raw JSON files.

After backfill, run batch transform:

python src/jira_transform.py \
    --raw-dir /data/src_data/raw/jira \
    --output-dir /data/src_data/parquet/jira \
    --attachments-dir /data/src_data/raw/jira/attachments

# Copy to distribution directory

SLA elapsed values (first_response_elapsed_millis, time_to_resolution_elapsed_millis) only update when a webhook fires. For idle open tickets (~49 tickets, ~0.3% of dataset), these values go stale and no longer reflect the actual current elapsed time.

File: scripts/jira_poll_sla.py

The SLA polling job runs every 15 minutes via systemd timer (jira-sla-poll.timer) as root:data-ops and:

1. Reads Parquet to find open issues with SLA data
2. Fetches fresh SLA and status fields via JSM service account (cloud API)
3. Updates raw JSON atomically (tempfile.mkstemp() + os.fchmod(fd, 0o660) + os.replace())
4. Triggers incremental Parquet transform (inside advisory file lock)

Self-healing: The poll fetches status, resolution, resolutiondate, and updated alongside the SLA fields. If a ticket is resolved in Jira but still appears "open" in Parquet (e.g. due to a missed webhook), the poll automatically corrects the status in JSON and re-transforms to Parquet. Log output: Self-healing: SUPPORT-XXXX is resolved in Jira. This was added in response to #203 where 12 tickets were permanently stale after a permission bug prevented webhooks from updating JSON files.

File locking: The entire read-modify-write + Parquet transform is wrapped in a per-issue advisory file lock (src/jira_file_lock.py) to prevent races with the webhook handler. The webhook handler (webapp/jira_service.py) uses the same lock. Different issue keys don't block each other.

Important — mkstemp and ACL: The issues/ directory uses POSIX ACLs with default:mask::rwx. tempfile.mkstemp() creates files with mode 0600, which overrides the ACL mask to --- and breaks group access for www-data (webhook handler) and deploy (batch transform). The os.fchmod(fd, 0o660) call immediately after mkstemp() restores the mask to rw-, preserving ACL-based access. See #203 for the full incident report.

# Manual run
python scripts/jira_poll_sla.py

# Dry run (count open issues)
python scripts/jira_poll_sla.py --dry-run

# Verbose logging
python scripts/jira_poll_sla.py --verbose

Return states:

• updated — SLA fields refreshed, status unchanged
• healed — status corrected (ticket was resolved in Jira but stale locally)
• skipped — no valid SLA data and ticket not resolved
• failed — API error or transform failure

Note: sla_cycle_type (ongoing/completed) is not stored in Parquet — compute it on-the-fly in DuckDB:

SELECT issue_key,
    CASE WHEN status_category = 'Done' THEN 'completed' ELSE 'ongoing' END AS sla_cycle_type,
    first_response_elapsed_millis,
    time_to_resolution_elapsed_millis
FROM 'server/parquet/jira/issues/*.parquet'
WHERE first_response_elapsed_millis IS NOT NULL

Analyst Sync Configuration

Jira data is an optional dataset - not synced by default to save bandwidth.

Enable Jira sync:

# Edit local config (created on first sync_data.sh run)
nano ~/.config/keboola-analyst/sync.yaml

# Change:
datasets:
  jira: true              # Enable parquet data (~50MB)
  jira_attachments: false # Keep false unless you need actual files

Then sync:

bash server/scripts/sync_data.sh

DuckDB views for Jira tables are created automatically if data exists:

• jira_issues - main issues table
• jira_comments - issue comments
• jira_attachments - attachment metadata (filenames, sizes, URLs)
• jira_changelog - field change history
• jira_issuelinks - links between issues (blocks, duplicates, relates to)
• jira_remote_links - external links (Confluence, Slack, etc.)

Attachment Access

Attachments (images, logs, PDFs) are stored separately from parquet data.

Option 1: Download per-ticket (recommended)

Download attachments for a specific ticket to local temp folder:

# Download all attachments for one ticket
rsync -avz data-analyst:server/jira_attachments/SUPPORT-1234/ /tmp/SUPPORT-1234/

# View locally
ls /tmp/SUPPORT-1234/
open /tmp/SUPPORT-1234/screenshot.png  # macOS

This is fast (only downloads files for one ticket) and keeps your local machine clean.

Option 2: Sync attachments locally (for heavy analysis)

If you need frequent access to attachments, enable full sync:

# ~/.config/keboola-analyst/sync.yaml
datasets:
  jira: true
  jira_attachments: true   # Syncs ~500MB+ of files

Then sync_data.sh will rsync attachments to ./server/jira_attachments/.

Finding attachment path from parquet

The jira_attachments table has a local_path column with the server path:

SELECT
    issue_key,
    filename,
    local_path,
    size_bytes
FROM jira_attachments
WHERE issue_key = 'SUPPORT-1234';

Result:

issue_key     | filename        | local_path                                           | size_bytes
SUPPORT-1234  | screenshot.png  | /data/src_data/raw/jira/attachments/SUPPORT-1234/... | 45678

To access locally (if synced): replace /data/src_data/raw/jira/attachments/ with ./server/jira_attachments/.

Future Improvements

• Automatic Parquet regeneration after each webhook (Implemented: incremental transform)
• Incremental Parquet updates (Implemented: upsert by issue_key)
• Full historical sync from Jira (Implemented: jira_backfill.py)
• SLA polling for open tickets (Implemented: jira_poll_sla.py, 15min timer)
• Comment attachment extraction (inline images in ADF)
• Custom field name resolution from Jira metadata API
• Attachment binary sync to analysts (currently metadata only)
