比MongoDB快12.7倍，比 ElasticSearch快500 倍以上，RedisJson到底是个啥

RedisJSON* is faster than MongoDB and ElasticSearch on direct read, write, and update workloads.
More concretely, when combining throughput and latency results, and given the context of benchmark details outlined further on this blog:
RedisJSON* is 5.4x times faster than MongoDB and >200x faster than ElasticSearch for isolated writes.
RedisJSON* is 12.7x times faster than MongoDB and >500x faster than ElasticSearch for isolated reads.

Redis官网关于RedisJSON的说明，大概意思是：

对于独立写入，RedisJSON* 比 MongoDB 快 5.4 倍，比 ElasticSearch 快 200 倍以上。对于隔离读取，RedisJSON* 比 MongoDB 快 12.7 倍，比 ElasticSearch 快 500 倍以上。
