详细说明： Redis is frequently compared to the likes of memcached and referred to as a "key value" store. This doesn't do it justice. The various data structures, it's atomic operations and pub/sub make this a viable replacement for queues, ESBs, caches and even databases. To really utilise redis some creative thinking is needed and this is where Redis in Action comes in. A well structured, well written book that covers pretty much every use case of redis in plenty of detail. It's nice to see a book not shy away from tackling the more challenging use cases for redis. The first 6 chapters are what I would consider foundation topics - whilst still very useful (like caching, logging & distributed locking) chapter 7 is where it starts to get interesting. As an aside chapter 4 is very useful and deals with configuring and working with redis to minimise the chance of data loss. It felt a bit odd that it was in the first part of the book, generally chapters focusing on configuration go towards the end of a book - not that it matters, just seemed odd! Chapter 7 onwards start to deal with interesting challenges in real world applications. By building out an Ad Server and social network the author tackles issues such as how to model none trivial data and relationships, index data and search/sort/filter. Chapters 9 & 10 deal with performance tuning and scaling redis. Some of the tips in here are worth the cost of the book alone if you're planning on using redis at scale. Chapter 11 covers how lua can be used to optimise performance. By reworking some of the earlier examples the author achieves a 20x performance improvement against the original autocomplete implementation. On future projects I'll be looking at using lua to speed things up. In summary this is a significant book that's well worth the price. Recommended. ...展开收缩
