# v1.2.1.1-RC.1

**Release Version:** v1.2.1.1-RC.1

**Release Type:** Release Candidate (RC)

**Release Date:** 1st June, 2026

### Overview

This Release Candidate (RC) introduces performance and stability enhancements to the Registration Processor ecosystem with a focus on improving packet processing throughput, optimizing resource utilization, and reducing latency across the processing pipeline.

The release includes code-level fine-tuning, infrastructure optimizations, and processing-stage improvements to improve scalability and operational stability under higher workloads.

As part of the performance validation carried out for this release, the system is now able to process approximately **3000 – 4000 packets per 10 minutes** in controlled performance test environments.

### Major Areas of Work

#### JVM & Resource Optimization

* Improved JVM memory and garbage collection tuning to reduce processing delays and improve pod stability under high throughput scenarios.
* Enhanced Kubernetes resource calibration to ensure better memory utilization and stable workload execution.

#### Packet Processing Performance Improvements

* Optimized packet validation and classification stages through reduced duplicate service calls and parallel execution of independent operations.
* Improved processing efficiency for biometric validation, document validation, and metadata retrieval.
* Reduced redundant Packet Manager and database calls across multiple stages to improve overall latency.

#### Database & Reprocessing Optimization

* Enhanced database performance for packet reprocessing through indexing improvements, reducing query execution time and improving retry handling efficiency.

#### Workflow & ABIS Throughput Improvements

* Improved ABIS middleware processing by offloading heavy response handling to worker threads.
* Optimized workflow internal actions through parallel execution of independent service operations.

#### Operational Stability Improvements

* Introduced asynchronous logging and worker pool fine-tuning capabilities to improve throughput and reduce processing overhead during peak load.
* Improved worker pool handling to allow better concurrency management across processing stages.
* Multiple code-level refinements to improve reliability and resilience during large-scale processing.
