Distributed Database Sharding Strategy for Microservices

sharding microservices distributed database scalability
Prompt
Design a horizontal sharding architecture for a microservices ecosystem using PHP, capable of distributing database load across multiple servers while maintaining data consistency and query performance. Develop a solution that supports dynamic shard allocation, implements consistent hashing for data distribution, and provides mechanisms for cross-shard transactions and data rebalancing. Include strategies for handling shard failures, implementing global secondary indexes, and maintaining referential integrity across distributed databases.
