Create a subpartitioned table

2023-07-21 09:11:01  Updated

Subpartitioning is a technique that partitions a table in two dimensions. For example, it is frequently used in scenarios that involve bills.

Subpartitioning types

OceanBase Database in MySQL mode supports the HASH, RANGE, LIST, KEY, RANGE COLUMNS, and LIST COLUMNS partitioning types, and a combination of any two of them can be used for subpartitioning. The following table describes the support for subpartitioned table creation.

Create a subpartitioned table

When you create a subpartitioned table, you can choose whether to use a template.

SQL syntax to create a subpartitioned table by using a template

CREATE TABLE [IF NOT EXISTS] table_name(column_option_list)
  [table_option_list] [partition_option_list];

column_option_list:

    INT_VALUE

Note

  • When you use a template to create a subpartitioned table, the template defines subpartitions under each partition. In this case, subpartitions under each partition share the same definition.
  • For a template-based subpartitioned table, the subpartitions are named in the format of ($part_name)s($subpart_name). For the tbl_rr table in the following example, the p0 partition has three subpartitions: p0smp1, p0smp2, and p0smp3.
obclient> CREATE TABLE tbl_rr(col1 INT,col2 INT,col3 INT)
       PARTITION BY RANGE(col1)

Parameters

Parameter Description
table_name The table name.
column_name The column name.
column_type The data type of the column.
locality_name The distribution of replicas across the zones. For example, F@z1,F@z2,F@z3,R@z4 indicates that z1, z2, and z3 are full-featured replicas, and z4 is a read-only replica.
primary_zone_name The primary zone where the leader resides.
partition_name The partition name.
subpartition_name The subpartition name.
INT_VALUE The number of HASH or KEY subpartitions.
