High-Performance Secure Networking with RIOC
- RIOC (Remote I/O Control) is a high-performance client-server protocol for interfacing with storage systems like HPKV.
- RIOC prioritizes latency, throughput, data consistency, and transport security in its design.
- Key optimizations in RIOC include vectored I/O to reduce system call overhead and zero-copy data transfers.
- Socket tuning in RIOC involves strategies like disabling Nagle's algorithm, adjusting buffer sizes, and setting low-latency parameters.
- RIOC uses lockless data structures such as lock-free sequence numbers, SPSC queues, and RCU for connection management.
- Concurrency in RIOC balances lockless algorithms, RCU-like patterns, fine-grained locking, and atomic operations for synchronization.
- Cache-conscious design principles in RIOC include cache line alignment, data locality optimization, and prefetching.
- Platform-specific optimizations in RIOC cater to Linux, macOS/BSD, and Windows environments for enhanced performance.
- RIOC's server architecture follows a thread-per-connection model with a worker pool to balance throughput and latency.
- RIOC implements TLS 1.3 with mutual authentication (mTLS) for secure client-server communication without compromising performance.

Unlocking the Power of PostgreSQL Table Inheritance: A Hidden Gem
- Table inheritance in PostgreSQL allows one table to inherit the structure and data of another table.
- It helps in keeping the database schema DRY (Don’t Repeat Yourself) and allows modeling of complex relationships without duplicating the structure.
- PostgreSQL table inheritance enables querying across tables and working with data of different types but with a common structure.
- It supports data partitioning and makes schema evolution easier, as changes to the parent table automatically reflect in the child tables.
