As a final step, we want to shift writes from Cirrus to SUP. To reduce the risk of loosing data, we take the following measures:
- only shift writes for public wikis
- only shift writes for one DC at a time
- only shift writes for a subset of wikis at a time
The batches are:
- testwiki; frwiki; itwiki; commonswiki; wikidatawiki (DC: CODFW)
- non-private rest (DC: CODFW)
AC:
- wmf-config: wgCirrusSearchWriteClusters reflects those changes
- SUP release consumer-search: --wikiids reflects those changes
