memlink's Introduction

特性 支持普通List/排序List/双向队列三种List类型。 List中的数据项(Item)支持一个主字段(整型、二进制)+若干个附属属性(bit),附属属性支持各种过滤操作 强一致性,任何写操作实时刷新bin-log,保证数据不丢失 采用块链和跳表精简内存使用,提升查找效率 支持多表定义(Ver0.5),不同表存储为不同数据文件便于迁移 支持主从同步 支持客户端 支持的客户端SDK都采用swig生成

C/C++ PHP Python Java 性能指标 采用自带perf(memlink/performance/perf)工具在4核 32G内存服务器上进行的测试,该测试是一个本地的单客户端压力测试,测试结果只能算是管中窥豹。
