Build from Source

git clone https://github.com/thisKK/taskrunna-framework.git
cd taskrunna-framework
./gradlew publishToMavenLocal

🎯 What's Included

• BatchJobProcessor - Main async processing engine with enhanced performance
• BaseBatchIterator - Cursor-based pagination for data sources
• BatchJobStats - Execution statistics and monitoring
• BatchMetrics - Prometheus metrics integration (enhanced)
• PrometheusConfig - Easy metrics setup utilities

🔍 Example Usage

import com.taskrunna.batch.*

// Your batch iterator
class OrderRetryIterator : BaseBatchIterator<OrderRetry>() {
    override fun loadNextBatch(cursor: String?, batchSize: Int): List<OrderRetry> {
        return orderService.findFailedOrders(cursor, batchSize)
    }
    override fun extractCursorFrom(item: OrderRetry): String = item.id
}

// Process with metrics
val processor = BatchJobProcessor(
    iterator = OrderRetryIterator(),
    submitJob = { order -> retryOrderAsync(order) },
    onSuccess = { order, result -> logger.info("✅ Retried order ${order.orderId}") },
    onFailure = { order, error -> logger.warn("⚠️ Failed to retry ${order.orderId}") },
    metrics = MicrometerBatchMetrics(prometheusRegistry, "order_retry")
)

processor.run() // 🚀 Enhanced performance with v1.1.2!

📊 Metrics & Observability

Enhanced Prometheus metrics with latest Micrometer:

• {prefix}_jobs_started_total - Batch jobs started
• {prefix}_jobs_completed_total - Batch jobs completed
• {prefix}_job_duration_seconds - Job execution time
• {prefix}_tasks_submitted_total - Individual tasks submitted
• {prefix}_tasks_completed_total - Individual tasks completed
• {prefix}_task_duration_seconds - Task execution time

Try the live example:

./gradlew :taskrunna-examples:run
curl http://localhost:8080/metrics | grep order_retry

🙏 Thanks

Special thanks to all contributors and the open-source community for the amazing libraries that make TaskRunna possible!

TaskRunna v1.1.0

🎉 Major Simplification - Single Package Release!

TaskRunna v1.1.0 makes batch processing much simpler by consolidating everything into one clean package!

✨ What's New

🎯 Single Dependency

• Before: taskrunna-core + taskrunna-batch (confusing!)
• Now: Just com.taskrunna:taskrunna:1.1.0 (simple!)

📦 Easy Installation

dependencies {
    implementation("com.taskrunna:taskrunna:1.1.0") // Everything included!
}

🚀 Production Ready

• ✅ Prometheus Metrics - 8+ built-in metrics for observability
• ✅ Working Examples - Order processing demo with HTTP server
• ✅ Published Package - Available on GitHub Packages
• ✅ Complete Docs - PUBLISHING.md, METRICS.md, comprehensive README

🔧 Quick Start

import com.taskrunna.batch.*

// Process orders from database → Send to Kafka
class OrderIterator : BaseBatchIterator<Order>() {
    override fun loadNextBatch(cursor: String, size: Int) = 
        orderRepository.findPendingOrders(cursor, size)
}
val processor = BatchJobProcessor(
    iterator = OrderIterator(),
    submitJob = { order -> sendToKafka(order) },
    onSuccess = { order, result -> markProcessed(order.id) }
)

processor.run() // Processes all orders asynchronously!

🆕 Try the Example
