表级别分区设置

单标分区，支持HASH/LIST/RANGE三种，每种分区只能参考一个字段

分区包含，全量数据拆分规则，增量拆分规则，以及全量，增量统一拆分规则

哈希分区(hash)

{
    "partition_type":"hash",
    "column_name":"col1",
    "hash_count":5,
    "hash_method":"auto", ##包含auto/manual两种模式
    "partition":[
        {
            "partition_no":0,
            "value":4
        },
        {
            "partition_no":1,
            "value":0
        },
        {
            "partition_no":2,
            "value":1
        },
        {
            "partition_no":3,
            "value":2
        },
        {
            "partition_no":4,
            "value":3
        }
    ]
}

列表分区(list)

• 支持数字，字符串两种类型

  {
   "partition_type":"list",
   "column_name":"col1",
   "column_type":"number",
   "partition":[
       {
           "partition_no":1,
           "value":[1,2,3]
       },
       {
           "partition_no":2,
           "value":[4,5,6]
       },
       {
           "partition_no":3,
           "value":[7,8,9]
       },
       {
           "partition_no":4,
           "value":[-1]
       }
   ]
  }

  范围分区(包含数字，字符串，时间)三中类型

  数字类型(long)

  {
   "partition_type":"range",
   "column_name":"col1",
   "column_type":"number",
   "partition":[
       {
           "partition_no":1,
           "max_value":123,
           "min_value":0
       },
       {
           "partition_no":2,
           "max_value":250,
           "min_value":124
       },
       {
           "partition_no":3,
           "max_value":500,
           "min_value":251
       },
       {
           "partition_no":0,
           "max_value":-1,
           "min_value":-1
       }
   ]
  }

  时间类型

  {
   "partition_type":"range",
   "column_name":"col1",
   "column_type":"datetime",
   "partition":[
       {
           "partition_no":1,
           "min_value":"2023-04-01 00:00:00",
           "max_value":"2023-04-30 23:59:59"
       },
       {
           "partition_no":2,
           "min_value":"2023-05-01 00:00:00",
           "max_value":"2023-05-31 23:59:59"
       },
       {
           "partition_no":3,
           "min_value":"2023-06-01 00:00:00",
           "max_value":"2023-06-30 23:59:59"
       },
       {
           "partition_no":0,
           "min_value":"1970-01-01 00:00:00",
           "max_value":"1970-01-01 00:00:00"
       }
   ]
  }

  字符串类型

  {
   "partition_type":"range",
   "column_name":"col1",
   "column_type":"string",
   "partition":[
       {
           "partition_no":1,
           "min_value":"a",
           "max_value":"b"
       },
       {
           "partition_no":2,
           "min_value":"c",
           "max_value":"d"
       },
       {
           "partition_no":3,
           "min_value":"e",
           "max_value":"f"
       },
       {
           "partition_no":0,
           "min_value":"g",
           "max_value":"g"
       }
   ]
  }
