[source-slack] Channel filtering: wildcard support, exclude list, external-channel toggle

[pnilan]

🤖 This issue was generated by an AI Agent.

What's missing

channel_filter matches channel names exactly. There is no way to match by pattern, to exclude channels, or to include/exclude externally-shared channels.

Verified on master

airbyte-integrations/connectors/source-slack/manifest.yaml line 221 filters on exact membership:

condition: "{{ record.name in config.channel_filter or not config.channel_filter }}"

is_ext_shared exists only as a record schema field, not as a config control.

Origin

Closed as stale: #74321 (hlepouse-vasco), reviewed 2026-04-16 with no author response.

Filed to keep a record of the gap. The PR was closed for inactivity, not on merit — credit to the original contributor if this is picked up.

Hi Patrick Nilan (@pnilan), thank you for reporting this!

We've escalated this to our team for investigation and tracking: airbytehq/oncall#13179

For anyone following along, the request covers three additions to source-slack channel selection: pattern/wildcard matching, an exclude list, and a toggle for externally-shared channels. If you have specific examples of the channel-naming patterns you'd want to match or exclude, please add them to this issue — that helps shape the design.
