A Redis Hash operates almost identically to a Python dictionary, allowing you to map multi-field records (such as option snapshots and stock summaries) directly without complex serialization.</li> <li><strong>Low Memory Footprint:</strong> Keeping data entirely in RAM using optimized memory allocators ensures massive datasets compress down to tiny footprints—typically consuming only a few megabytes for thousands of structured records.</li> <li><strong>Robustness &amp; High Availability:</strong> Built to be a permanent infrastructure fixture with persistence options (RDB snapshots and AOF logs) and replication architectures like Sentinel to guarantee uptime.</li> </ul> <ol start="2"> <li>Installation on Linux and Raspberry Pi</li> </ol> <hr> <p>Installing Redis on Debian/Ubuntu Linux distributions (including Raspberry Pi OS) is fast and reliable via the native package manager:</p>
