ODP V4.3.4 is the latest version in the V4.3.x series, which enhances the routing capabilities of SQL and RPC proxies, and improves high availability and stability.
SQL proxy routing capabilities: Supports routing based on Asian character sets/collations, functions as partitioning keys, optimized routing for JOIN operations involving replicated tables, and accurate routing for requests over 4 KB in length.
RPC proxy routing capabilities: Supports accurate routing for single-partition tables, guarantees atomicity in partition information retrieval, and supports multiple tablet requests for LSOP.
Stability: Introduces a global parameter, server_protocol, to specify the protocol type between ODP and OceanBase Database, assisting in troubleshooting protocol issues and enhancing stability.
High availability: Refines the congestion handling process for RPC proxies to ensure no requests are forwarded to abnormal OBServer ndoes under any circumstances, and asynchronously retrieves ls_id information to reduce pressure on the SYS tenant of OceanBase Database.
