Create a data table using the CreateTable operation-Tablestore(Tablestore)-阿里云帮助中心

You can call the CreateTable operation to create a data table with the specified table schema.

Notes

A newly created table is not immediately available for read and write operations. You must wait for about one minute after the table is created before you can perform these operations.
You can create a maximum of 64 tables in a single instance. To increase this limit, submit a ticket.

Request message structure

message CreateTableRequest {
    required TableMeta table_meta = 1;
    required ReservedThroughput reserved_throughput = 2; 
    optional TableOptions table_options = 3;
    repeated PartitionRange partitions = 4;
    optional StreamSpecification stream_spec = 5;
    optional SSESpecification sse_spec = 6;
    repeated IndexMeta index_metas = 7;
    optional bool enable_local_txn = 8;
}

Parameter	Type	Required	Description
table_meta	TableMeta	Yes	The schema of the data table. This includes the following configuration items: Important After a table is created, its schema cannot be modified. table_name: The name of the table. The name must be unique within the instance. primary_key: The primary key. The primary key must contain one to four primary key columns (ColumnSchema). The name of each primary key column must follow the naming conventions and data type rules. The type can only be STRING, INTEGER, or BINARY. For more information about naming conventions and data types, see Naming conventions and data types. defined_Columns: The predefined columns. To use a secondary index, add predefined columns to the data table. Define non-primary key columns and their types in advance to use them as attribute columns or index columns for an index table. You can also add predefined columns after creating the table. For more information, see How to use predefined columns.
reserved_throughput	ReservedThroughput	Yes	The reserved read throughput and reserved write throughput for the data table. The reserved read throughput and the reserved write throughput cannot exceed 100,000 each. The unit is CU. Use the UpdateTable operation to change the reserved read and write throughput.
table_options	TableOptions	No	Includes settings such as TimeToLive and max versions.
partitions	PartitionRange	No	The partition range of the data table.
stream_spec	StreamSpecification	No	Specifies whether to enable stream properties.
sse_spec	SSESpecification	No	The encryption configuration for the data table.
index_metas	IndexMeta	No	The schema of the index table.
enable_local_txn	bool	No	Specifies whether to enable the local transaction feature for the data table. The default value is false. To perform atomic operations for single-row or multi-row reads and writes, enable the local transaction feature for the data table.
