4.3 makeBucketArray makeBucketArray 方法会进行桶数组的初始化,并根据桶的数量决定是否需要提前作溢出桶的初始化. 方法主干代码如下: func makeBucketArray(t *maptype, b uint8, dirtyalloc unsafe.Pointer) (buckets unsafe.Pointer, nextOverflow *bmap) { base := bucketShift(b) nbuckets := base if b...
redis(REmote DIctionary Server)是一个由Salvatore Sanfilippo写key-value存储系统,它由C语言编写、遵守BSD协议、支持网络、可基于内存亦可持久化的日志型、Key-Value类型的数据库,并提供多种语言的API。和Memcached类似,它支持存储的value类型相对更多,包括string(字符串)、list(链表)、set(集合)、zset(sorted set --...

values [8]valuetype overflow uintptr } 每个桶里包括8个key和8个value,和对应的8个tophash值,其中tophash值是hash值的高8位 tophash:用于map查找中第一次比对,如果tophash值相同,接下来比对key值。 桶中数据的存储:8个key放在一起,8个value放在一起,作用是减少填充的空隙,节省空间。
