# Store Tree in Redis

Storing Tree structure in redis. ... Redis doesn't support nested data structures, so we need to represent data and parent attributes as redis HASH and children as redis LIST. Reading a tree node requires two calls to redis, one to get the details of the node and second one to get the list of children.

表结构设计，假设父节点单一：

{
    "parent" : 1,
    "children" : [3, 5, 6],
    "data" : {
        
    }
}
