Background job queue for long-running sync tasks

[Jagadeeshftw]

Description

Summary

Within the Fluxora HTTP and indexing services, this work clarifies predictable behavior for a single responsibility area. The Fluxora backend must present operator-grade reliability: predictable HTTP semantics, durable views of chain-derived data where required, and explicit failure behavior when the world outside the process is messy. This issue is scoped by its title—Background job queue for long-running sync tasks—and should close gaps between what stakeholders expect and what the service actually guarantees. Address abuse scenarios: oversized payloads, excessive request rates, and duplicate submissions, with predictable client-visible outcomes. Deliver verification appropriate to risk (tests, staging drills, or written runbooks). Anything intentionally deferred should be recorded with follow-up tracking.

Issue caption: Background job queue for long-running sync tasks

Domain context

The Fluxora backend is the off-chain companion to the streaming contract: it should present a trustworthy,
operator-grade HTTP surface for discovery and automation, persist durable views of chain-derived state where required,
and fail safely when dependencies (database, Stellar RPC, workers) are unhealthy. Amounts and identities crossing the
boundary from chain to API must remain unambiguous for clients and auditors.

Work to complete

1. Define the service-level outcomes for Background job queue for long-running sync tasks, treating the Summary above as the authoritative scope statement.
2. Identify trust boundaries: public internet clients, authenticated partners, administrators, and internal workers; state what each may and may not do.
3. List failure modes (invalid input, dependency outage, partial data, duplicate delivery) and the expected client-visible behavior for each.
4. Describe how operators will observe health and diagnose incidents for this area without relying on tribal knowledge.

Definition of done

• Evidence shows Background job queue for long-running sync tasks behaves as specified under normal load and representative failure conditions.
• Automated tests or monitored checks cover regressions for the critical paths implied by this issue.
• The change set documents verification steps and calls out any intentional non-goals or follow-up work.

Constraints for contributors

• Describe outcomes, invariants, and evidence, not a single “right” internal design unless the issue title already names a concrete subsystem.
• Prefer observable guarantees: state transitions, balances, authorization failures, emitted events, error classifications, and documentation that integrators rely on.
• If something cannot be tested automatically, capture the gap as audit notes with explicit rationale and residual risk.

Requirements and context

• Must be secure, tested, and documented (OpenAPI where applicable).
• Should be efficient, observable, and easy to review for operators.

Suggested execution

1. Fork the repo and create a branch:

   git checkout -b feature/fluxora-backend

2. Implement changes
   • Service code: Fluxora-Backend/src/**
   • Tests: Fluxora-Backend/tests/** and colocated *.test.ts as adopted
   • Documentation: inline README sections (no new markdown file unless explicitly requested)
   • Validate assumptions (auth, idempotency, Stellar RPC semantics)
3. Test and commit
   • Run npm test / pnpm test (match package manager)
   • Cover edge cases (validation, pagination, failure modes)
   • Include test output + operational notes in the PR

Example commit message

feat(api): fluxora backend work

Guidelines

• Aim for ≥95% coverage on new/changed backend modules (unit + integration).
• Clear API behavior documented via OpenAPI or route comments
• Timeframe: 96 hours
