ores.scheduler.core

ores.scheduler.core provides cron-based job scheduling for ORE Studio. It manages job definitions (cron expressions, target actions) and job instances (execution history, status), runs a persistent scheduler loop that fires due jobs, and exposes NATS handlers for querying and managing jobs at runtime. It supports SQL, NATS-publish, and message-queue action types, making it the general-purpose periodic-operation backbone for the platform.

• NATS request messages for job-definition CRUD and instance queries.
• PostgreSQL connections to ores_scheduler_* tables for job persistence.
• System clock for evaluating cron expressions.

• Job-definition and job-instance records persisted to the ores_scheduler schema.
• Triggered actions: SQL statements executed, NATS messages published, or MQ actions dispatched per job schedule.
• NATS response messages returned to callers.
