OpenMLDB ttl setting

逻辑梳理

  1. hybridse GetAbsTTL可能为-2，-1，[0, MAX]。其中，-2为默认值，应该理解为“不gc”；-1是无效设置时赋予的值，如果GetAbsTTL为-1，就应报错； [0, MAX]则是有效的ttl值 -> 推论：GetAbsTTL为0时，不应该理解为不gc，而应该是一个极短的ttl。<1min的值都可以提升为1min的ttl（结构common::TTLSt）

问题即（ttl_type=absolute,ttl=0m)是不gc还是1min？——结论：不gc

  1. 目前openmldb的create table/create index是没有特殊处理“小于1min的abs ttl”，导致如果GetAbsTTL大于等于0小于1min时，转换出来的abs ttl 就是0，即不gc
  2. 不仅是小于1min的，规则应该是换算为min时向上取整

openmldb test sample

openmldb/bin/openmldb --zk_cluster=127.0.0.1:2181 --zk_root_path=/openmldb --role=sql_client < test.sql 即可 注意test.sql内，c1.csv的路径，需要跟taskmanager（spark.home=local）在同一台机器上，并且写绝对路径。 输出结果里都是SUCCEED，没有ERROR就可以。
