What the data for this category looks like
Core data for film theaters comes from theater scheduling management systems, third-party ticketing platform open APIs, in-house marketing material libraries, and member operation systems. Scheduling data updates daily per individual screening, and includes fields such as theater number, screening time, associated film ID, and base ticket price. The marketing material library stores trailers, posters, promotional copy, and other content, categorized by material type, resolution, and associated film ID. Member system data includes viewing preferences, ticket purchase frequency, and other metrics, linked by member ID. Data update rhythms include scheduled batch updates (scheduling data), on-demand triggers (marketing material uploads), and real-time sync (member behavior data). Field units uniformly use ISO 8601 timestamps, Chinese Yuan (RMB), and pixel resolution.
What constraints these characteristics impose on workflow orchestration
The per-screening update nature of scheduling data means workflows cannot use full scheduled triggers. Incremental sync trigger rules must be configured to only process updated screening data, and avoid duplicate marketing content delivery. The multi-resolution requirement for marketing materials means a format conversion node must be added to the workflow to fit specifications of different delivery channels. The business logic linking films and screenings means workflow variable references must pass both film ID and screening ID to accurately match corresponding marketing materials. Strict marketing time windows mean workflows must set reasonable timeouts and retry counts to avoid missing delivery windows.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
trigger_mode | Incremental trigger (by session update time) | Theater scheduling data updates per individual screening. Full scheduled triggers will repeatedly process already handled screening data |
db_connect_timeout | 30 seconds | Theater databases are mostly deployed on internal networks. An overly short timeout setting will cause connection failures, while an overly long one will block workflow queues |
variable_ref_format | [{"film_id": "{{film_id}}", "schedule_id": "{{show_schedule_id}}"}] | Marketing content must be bound to specific films and screenings. Two-dimensional associated parameters must be passed |
media_resize_limit | 1080p、720p、480p | Fit resolution requirements of different delivery channels including theater official accounts, cinema self-service terminals, and third-party ticketing platforms |
workflow_retry_times | 2 times | Theater marketing activities have strict time windows. Too many retries will miss delivery windows |
max_batch_process | 10 entries per call | Processing too many screenings in a single batch will cause excessive database load, and affect the stability of theater ticketing systems |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material formats, data volume, and business rules. Specific issues require specific analysis, and it is recommended to test on your own samples before finalizing.
Three common mistakes
- Phenomenon: An error "Workflow verification failed, please check for missing or empty fields, and correct wiring" occurs when running the database connection node. Cause: The internal network address, port, or authentication key for PostgreSQL was not filled in correctly, or the
db_connect_timeoutparameter was not configured, so connection timeouts were not caught. - Phenomenon: The marketing material generation node outputs resolutions that do not meet delivery requirements. Cause: The
media_resize_limitparameter was not set, or a resolution specification beyond what theater delivery channels support was selected. - Phenomenon: Fixed data analysis operations cannot be reused, and the work order data source must be reselected each time the workflow runs. Cause: The current workflow's data source configuration was not saved as a template, or the corresponding configuration item was not enabled.
How to confirm the configuration is correct
- Manually trigger the workflow bound to a single screening, check the node logs, confirm that the database node can normally pull scheduling data for the corresponding
show_schedule_idwithout connection errors. - Upload a test poster that conforms to standard theater material specifications, check the output of the format conversion node, confirm that the resolution meets the requirements set in the
media_resize_limitconfiguration. - Enter preset
film_idandshow_schedule_idvariables, check that the corresponding content in the marketing material library can be correctly matched after variable substitution. - Simulate a database connection timeout scenario, confirm that the workflow retries according to the
workflow_retry_timesconfiguration, and that the number of retries does not exceed the set value.
