Database and Operations for Solid Waste Treatment Yield

Data Structure for This Category

Solid waste treatment project yield rate and daily market data originates from project operation ledgers, sanitation haulage metering systems, regional solid waste disposal bidding platforms, and local environmental protection regulatory public datasets. The system updates data once daily to align with daily report requirements. Each data entry covers the daily operation details of one disposal site or project. Fields include site code, daily disposal volume, disposal service fee unit price, daily operating cost, daily net income, and additional relevant fields. All fields use fixed units, and no complex nested structures exist.

Constraints for Database and Operations Workflows

Multi-source data access creates format validation requirements. Field naming for ledger data from different sources varies, so unified mapping to system preset fields is required. The daily incremental sync rhythm requires scheduled trigger tasks to avoid data delays or duplicates. Fields with fixed units must undergo format validation before storage to prevent dirty data from entering the system and disrupting subsequent reports. Additionally, classification attributes of solid waste treatment projects must be stored separately to support future data filtering by disposal type. Full sync logs and modification records must be retained to meet data traceability requirements.

Configuration Parameters

Configuration Item	Recommended Value	Rationale
`SYNC_DATA_INTERVAL`	`86400 seconds`	Matches the daily update rhythm of solid waste treatment yield rate daily reports to ensure data timeliness
`DATA_VALIDATION_RULES`	`Enable ton and yuan unit validation, filter non-numeric fields`	Adapts to the fixed unit characteristics of solid waste treatment data to prevent dirty data from being stored
`MAX_CONCURRENT_TASKS`	`10–15`	Balances resource usage and sync efficiency for multi-site synchronization, and adapts to single-node hardware configurations
`DB_BACKUP_CRON`	`0 1 * * *`	Runs backups daily at 1 AM, aligns with the maintenance window after that day's data is generated
`PARSE_FIELD_MAPPING`	`Map fields to site code, disposal volume, unit price, cost, net income`	Unifies field naming across multi-source data to ensure consistent data structure
`RETRY_TIMES`	`3 times`	Addresses temporary rate limiting from external market interfaces to improve data sync success rates

The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require individual analysis. Testing against local samples is recommended before finalizing settings.

Three Common Configuration Errors

Database queries return empty fields. Missing PARSE_FIELD_MAPPING rules leads to mismatches between multi-source data field names and system preset fields, preventing correct data mapping.
Synchronization tasks trigger 504 Gateway Timeout errors. Failure to adjust the SYNC_DATA_TIMEOUT parameter causes excess response delays from external solid waste trading platform interfaces, exceeding default thresholds.
Resource blocking occurs during concurrent multi-user requests. Failure to adjust MAX_CONCURRENT_TASKS based on hardware configurations causes concurrent requests to exceed the task capacity of the node.

How to Verify Proper Configuration

Run a manual data sync task, and verify that synced fields match the mapping rules defined in PARSE_FIELD_MAPPING.
Check the data_validation_log table to confirm no unit validation or format error alerts were triggered for that day's synced data.
Simulate concurrent multi-user requests, observe system resource usage, and adjust MAX_CONCURRENT_TASKS to a reasonable range.
Review scheduled backup task execution logs to confirm daily backup tasks complete normally, and that backup files can load data correctly using recovery commands.
