📊 New Configuration Options
Batch Processing Configuration
{
"batchProcessing":{
"enableBatchProcessing":true,
"batchSize":10,
"concurrency":3,
"delayBetweenBatches":1000,
"maxRetries":3,
"failureThreshold":0.5,
"enableProgressTracking":true,
"resumeFromLastBatch":true
}
}
URL List Management
{
"urlListManagement":{
"enableDeduplication":true,
"enableValidation":true,
"maxUrlsPerBatch":1000,
"blockedDomains":["spam.com"],
"allowedDomains":["trusted.com"],
"urlPatterns":{
"includePatterns":[".*\\.jpg$"],
"excludePatterns":[".*admin.*"]
}
}
}
Media Conversion Options
{
"conversionOptions":{
