Enhancements

Vortex on AWS: Enabled Crypto API support and replication groups for Vortex on AWS, allowing integration with the QA environment in AWS. Enhanced the Crypto Broker to handle DKUPT encrypted PIN decryption for Payment Broker operations without reliance on the Hardware Security Module.
Payment Broker with Sync Persistence: Implemented a persistence monitor to ensure synchronous database updates, eliminating risks related to duplicate transactions.
Vortex Payments to Checkout Parity: Introduced several enhancements to ensure Vortex supports all transaction types from Checkout, including:
- Support for encrypted EMV data in the Payment Broker API.
- Support for MX Advantage transaction types with fees, BIN Lookup, and enriched fee paths.
- Card-present transaction types: Contact EMV, Contact EMV + PIN, Contactless EMV (NFC), Contactless Swipe (AMEX), EMV Fallback, and Swipe.
MemSQL to MySQL Migration: Transitioned from MemSQL to MySQL, updating various Vortex components like the Payment Broker, Crypto Broker, and other bots to integrate with MySQL. The MemSQL database was initially used as a secondary data source during stability testing before it became the primary data source.
Settlement Update File Enhancement: Enhanced the Settlement Update file to include the batch number and merchant account number, providing better batch management for Passport. Two additional fields were added to the file: Batch Id and Merchant Number.

Vortex Stabilization Effort: A series of improvements were made to stabilize Vortex, including:
- Transitioned Checkout to use replication groups instead of virtual environments.

- Updated broker-client and svc-discovery package dependencies to resolve configuration conflicts.
- Corrected Etcd lease expiration issue in QA, preventing pod crashes.
- Added a flag to Recruitment and Settlement Bots to prevent concurrent settlement cutoffs.
