## Summary
Review and fix missing or incorrect Sidekiq worker attributes across all workers in the Global Search domain (`Search::Elastic::`, `Search::Zoekt::`, `Elastic::`, `Ai::ActiveContext::`, and remaining flat `Elastic*` workers).

## `data_consistency :always` — investigate and fix
`:always` is strongly discouraged per docs. Most were set mechanically in 2021. Each needs analysis before changing to `:sticky`.
- [x] `ElasticClusterReindexingCronWorker` — change to `:sticky` (cron, no need for primary) (!239628)
- [ ] `ElasticDeleteProjectWorker` — investigate: uses DB reads, determine if `:sticky` is safe
- [ ] `ElasticFullIndexWorker` — change to `:sticky`
- [ ] `ElasticNamespaceRolloutWorker` — change to `:sticky`
- [ ] `Search::Elastic::MetricsUpdateCronWorker` — change to `:sticky`
- [ ] `Search::Zoekt::SchedulingWorker` — investigate: determine if `:always` is intentional
## Missing `urgency`
Workers default to `:low` when not set. Verify this is correct or set the appropriate value.
- [ ] `ElasticAssociationIndexerWorker` — should it be `:throttled`?
- [ ] `ElasticFullIndexWorker` — should it be `:throttled`?
- [ ] `ElasticNamespaceIndexerWorker` — should it be `:throttled`?
- [ ] `ElasticNamespaceRolloutWorker` — investigate
- [ ] `Elastic::NamespaceUpdateWorker` — investigate
- [ ] `Search::ElasticDefaultBranchChangedWorker` — confirm `:low` is correct
- [ ] `Search::ElasticRetryQueueCronWorker` — investigate
## Missing `idempotent!` / `rubocop:disable Scalability/IdempotentWorker`
- [ ] `ElasticFullIndexWorker` — investigate: can it be made idempotent? Remove rubocop disable?
- [ ] `ElasticIndexBulkCronWorker` — intentionally non-idempotent (processes queue); confirm this is still valid
- [ ] `ElasticIndexInitialBulkCronWorker` — same as above
- [ ] `ElasticNamespaceRolloutWorker` — investigate: can it be made idempotent?
- [ ] `Elastic::NamespaceUpdateWorker` — investigate: can it be made idempotent?
- [ ] `Search::ElasticRetryQueueCronWorker` — non-idempotent by design; confirm still valid
## Missing `deduplicate`
- [ ] `ElasticAssociationIndexerWorker` — add `:until_executed`?
- [ ] `ElasticDeleteProjectWorker` — add `:until_executed`?
- [ ] `ElasticFullIndexWorker` — investigate
- [ ] `ElasticWikiIndexerWorker` — add `:until_executed`?
- [ ] `Elastic::MigrationWorker` — add `:until_executed`?
- [ ] `Elastic::NamespaceUpdateWorker` — add?
- [ ] `Elastic::ProjectTransferWorker` — add?
- [ ] `Search::ElasticDefaultBranchChangedWorker` — add?
- [ ] `Search::ElasticGroupAssociationDeletionWorker` — add?
- [ ] `Search::Elastic::CommitIndexerWorker` — add?
- [ ] `Search::Elastic::DeleteWorker` — add?
- [ ] `Search::Elastic::TriggerIndexingWorker` — add?
- [ ] `Search::Wiki::ElasticDeleteGroupWikiWorker` — add?
- [ ] `Search::Zoekt::DefaultBranchChangedWorker` — add?
- [ ] `Search::Zoekt::ProjectTransferWorker` — add?
- [x] `Ai::ActiveContext::BulkProcessWorker` — add `:until_executed`? https://gitlab.com/gitlab-org/gitlab/-/merge_requests/255045
- [x] `Ai::ActiveContext::ConnectionCleanupWorker` — add? https://gitlab.com/gitlab-org/gitlab/-/merge_requests/255045
- [x] `Ai::ActiveContext::DisableWorker` — add? https://gitlab.com/gitlab-org/gitlab/-/merge_requests/255045
## Missing `pause_control`
- [ ] `ElasticClusterReindexingCronWorker` — add `:advanced_search`?
- [ ] `Elastic::MigrationWorker` — add `:advanced_search`?
- [ ] `Elastic::NamespaceUpdateWorker` — add `:advanced_search`?
- [ ] `Elastic::ProjectTransferWorker` — add `:advanced_search`?
- [ ] `Search::ElasticDefaultBranchChangedWorker` — add `:advanced_search`?
- [ ] `Search::Elastic::MetricsUpdateCronWorker` — add `:advanced_search`?
- [ ] `Search::Elastic::TriggerIndexingWorker` — add `:advanced_search`?
- [ ] `Search::Zoekt::DefaultBranchChangedWorker` — confirm no pause_control needed
- [ ] `Search::Zoekt::IndexingTaskWorker` — confirm no pause_control needed
- [ ] `Search::Zoekt::MetricsUpdateCronWorker` — add `:zoekt`?
- [ ] `Search::Zoekt::RolloutWorker` — add `:zoekt`?
- [ ] `Search::Zoekt::SchedulingWorker` — add `:zoekt`?
- [ ] `Ai::ActiveContext::ConnectionCleanupWorker` — add `:active_context`? Blocked by #628918.
- [x] `Ai::ActiveContext::DisableWorker` — add `:active_context`? Won't fix. It's the kill-switch itself, and `Ai::ActiveContext.paused?` requires an active connection, so pausing this worker would trap it with no way to self-release.
## Missing `defer_on_database_health_signal`
All older workers lack this. Add `:gitlab_main` with appropriate tables and a 10-minute timeout, following the pattern of newer workers like `Search::Zoekt::IndexingTaskWorker`.
- [ ] `ElasticAssociationIndexerWorker`
- [ ] `ElasticClusterReindexingCronWorker`
- [ ] `ElasticDeleteProjectWorker`
- [ ] `ElasticFullIndexWorker`
- [x] `ElasticIndexBulkCronWorker` https://gitlab.com/gitlab-org/gitlab/-/merge_requests/240422
- [x] `ElasticIndexInitialBulkCronWorker` https://gitlab.com/gitlab-org/gitlab/-/merge_requests/240801
- [ ] `ElasticNamespaceIndexerWorker`
- [ ] `ElasticNamespaceRolloutWorker`
- [ ] `ElasticWikiIndexerWorker`
- [ ] `Elastic::MigrationWorker`
- [ ] `Elastic::NamespaceUpdateWorker`
- [ ] `Elastic::ProjectTransferWorker`
- [ ] `Search::ElasticDefaultBranchChangedWorker`
- [ ] `Search::ElasticGroupAssociationDeletionWorker`
- [ ] `Search::ElasticRetryQueueCronWorker` — has `:gitlab_main` but missing tables/timeout; update
- [ ] `Search::Elastic::CommitIndexerWorker`
- [ ] `Search::Elastic::DeleteWorker`
- [ ] `Search::Elastic::MetricsUpdateCronWorker`
- [ ] `Search::Elastic::MigrationCleanupCronWorker`
- [ ] `Search::Elastic::TriggerIndexingWorker`
- [ ] `Search::Elastic::RemoveExpiredNamespaceSubscriptionsFromIndexCronWorker`
- [ ] `Search::Zoekt::DefaultBranchChangedWorker`
- [ ] `Search::Zoekt::MetricsUpdateCronWorker`
- [ ] `Search::Zoekt::ProjectTransferWorker`
- [ ] `Search::Wiki::ElasticDeleteGroupWikiWorker`
- [ ] `Search::NamespaceIndexIntegrityWorker`
- [ ] `Search::ProjectIndexIntegrityWorker`
- [x] `Ai::ActiveContext::BulkProcessWorker` — has `:gitlab_main` but missing tables/timeout; update https://gitlab.com/gitlab-org/gitlab/-/merge_requests/255045
- [x] `Search::ExpireFinderCacheWorker` — has `rubocop:disable Sidekiq/EnforceDatabaseHealthSignalDeferral`; investigate if deferral can be added
## Missing `worker_resource_boundary`
CPU-intensive workers should be annotated. Investigate each:
- [ ] `ElasticClusterReindexingCronWorker` — add `:cpu`?
- [ ] `ElasticDeleteProjectWorker` — add `:cpu`?
- [ ] `ElasticFullIndexWorker` — add `:cpu`?
- [ ] `ElasticNamespaceRolloutWorker` — add `:cpu`?
- [ ] `ElasticWikiIndexerWorker` — add `:cpu`?
- [ ] `Elastic::MigrationWorker` — add `:cpu`?
- [ ] `Elastic::NamespaceUpdateWorker` — add `:cpu`?
- [ ] `Elastic::ProjectTransferWorker` — add `:cpu`?
## Missing `loggable_arguments`
Workers with meaningful arguments should declare them for structured logging:
- [ ] `ElasticDeleteProjectWorker` — `project_id`, `es_id`, `options`
- [ ] `ElasticFullIndexWorker` — `start_id`, `end_id`
- [ ] `Elastic::ProjectTransferWorker` — `project_id`, `old_namespace_id`, `new_namespace_id`
- [ ] `Search::ElasticGroupAssociationDeletionWorker` — investigate
## Other
- [ ] `Search::ExpireFinderCacheWorker` — does not include `Search::Worker` (has explicit `feature_category`); investigate whether it should include `Search::Worker` for consistency
