TableRequest

class borneo.TableRequest

Bases: borneo.operations.Request

TableRequest is used to create, modify, and drop tables. The operations allowed are those supported by the Data Definition Language (DDL) portion of the query language. The language provides for table creation and removal (drop), index add and drop, as well as schema evolution via alter table. Operations using DDL statements infer the table name from the query statement itself, e.g. “create table mytable(…)”. Table creation requires a valid TableLimits object to define the throughput desired for the table. If TableLimits is provided with any other type of query statement an exception is thrown.

This request is also used to modify the limits of throughput and storage for an existing table. This case is handled by specifying a table name and limits without a query statement. If all three are specified it is an error.

Execution of operations specified by this request is implicitly asynchronous. These are potentially long-running operations. NoSQLHandle.table_request() returns a TableResult instance that can be used to poll until the table reaches the desired state.

The statement is required parameter unless modifying limits.

Methods Documentation

get_compartment()

Cloud service only.

Get the compartment id or name if set for the request.

Returns:compartment id or name if set for the request, otherwise None if not set. Return type:str

get_statement()

Returns the statement, or None if not set.

Returns:the statement. Return type:str

get_table_limits()

Returns the table limits, or None if not set.

Returns:the limits. Return type:TableLimits

get_table_name()

Returns the table name to use for the operation.

Returns:the table name, or None if not set. Returns:str

get_timeout()

Returns the timeout to use for the operation, in milliseconds. A value of 0 indicates that the timeout has not been set.

Returns:the timeout value. Return type:int

set_compartment(compartment)

Cloud service only.

Sets the name or id of a compartment to be used for this operation.

The compartment may be specified as either a name (or path for nested compartments) or as an id (OCID). A name (vs id) can only be used when authenticated using a specific user identity. It is not available if authenticated as an Instance Principal which can be done when calling the service from a compute instance in the Oracle Cloud Infrastructure. See borneo.iam.SignatureProvider.create_with_instance_principal().

Parameters:compartment (str) – the compartment name or id. If using a nested compartment, specify the full compartment path compartmentA.compartmentB, but exclude the name of the root compartment (tenant). Returns:self. Raises:IllegalArgumentException – raises the exception if compartment is not a str.

set_statement(statement)

Sets the query statement to use for the operation. This parameter is required unless the operation is intended to change the limits of an existing table.

Parameters:statement (str) – the statement. Returns:self. Raises:IllegalArgumentException – raises the exception if statement is not a string.

set_table_limits(table_limits)

Cloud service only.

Sets the table limits to use for the operation. Limits are used in only 2 cases – table creation statements and limits modification operations. It is not used for other DDL operations.

If limits are set for an on-premise service they are silently ignored.

Parameters:table_limits (TableLimits) – the limits. Returns:self. Raises:IllegalArgumentException – raises the exception if table_limits is not an instance TableLimits.

set_table_name(table_name)

Sets the table name to use for the operation. The table name is only used to modify the limits of an existing table, and must not be set for any other operation.

Parameters:table_name (str) – the name of the table. Returns:self. Raises:IllegalArgumentException – raises the exception if table_name is not a string.

set_timeout(timeout_ms)

Sets the request timeout value, in milliseconds. This overrides any default value set in NoSQLHandleConfig. The value must be positive.

Parameters:timeout_ms (int) – the timeout value, in milliseconds. Returns:self. Raises:IllegalArgumentException – raises the exception if the timeout value is less than or equal to 0.
