- Added leader election mechanism using Redis to ensure only one instance runs scheduled jobs at a time. - Created `src/services/leaderElection.js` for managing leader lease acquisition, renewal, and release. - Introduced `src/jobs/leaderAwareJob.js` to wrap existing jobs with leader election logic. - Updated `src/index.js` to utilize wrapped jobs for price refresh, webhook retry, and airdrop expiry. - Enhanced health check endpoint to report leadership status for each job. - Added configuration options for instance ID, lease TTL, and renewal interval in `src/config.js`. - Documented leader election mechanism and configuration in `README.md`. - Created comprehensive tests for leader election functionality in `test/leaderElection.test.js`.
