[I] [Feature] Support for prefix matching and index persistence [dubbo-admin]

["tew-axiom (via GitHub)" <gi...@apache.org>]

tew-axiom opened a new issue, #1389:
URL: https://github.com/apache/dubbo-admin/issues/1389

   <!-- Please only use this template for submitting feature requests -->
   
   **What would you like to be added**:
   
   Support for prefix matching and index persistence in dubbo-admin's indexing system. Specifically:
   
   1. **Prefix Matching Support**:
      - Extend index query logical operators beyond simple equality matches to support prefix-based searches
      - For memory storage: Implement Trie data structure to enable efficient prefix matching
      - For database storage: Design and implement database queries that support prefix matching along with other composite conditions
   
   2. **Index Persistence for Database Storage**:
      - Create a new database table to persist indexes when using DB-backed storage
      - Ensure index consistency across multiple replicas in Master-Slave deployment architecture
      - Enable all replicas to access persisted indexes for frontend query operations
   
   3. **Indexer Refactoring**:
      - Expand logical operators in the `Indexer` definition beyond the current "Equals" operator
      - Refactor the `Indexer` interface to support extended query capabilities
      - Update dependent components including `Manager` and `Console` to work with the new indexing system
   
   **Why is this needed**:
   
   Related to #1381 proposal.
   
   Currently, dubbo-admin's indexing system has the following limitations:
   - Only supports simple equality matching, lacking prefix-based search capabilities
   - In multi-replica deployments with database storage, indexes are only maintained in memory on the leader replica, causing query inconsistencies
   - The current index structure (map[idx_value][resource_key]) is too simple to support advanced query requirements
   
   This enhancement will:
   - Enable more flexible and powerful search capabilities for users querying resources
   - Ensure data consistency and availability in distributed deployments
   - Improve the overall scalability and reliability of dubbo-admin in production environments
