data CapacitySpecification

Amazon Keyspaces has two read/write capacity modes for processing reads and writes on your tables:

• On-demand (default)

• Provisioned

The read/write capacity mode that you choose controls how you are charged for read and write throughput and how table throughput capacity is managed.

For more information, see Read/write capacity modes in the Amazon Keyspaces Developer Guide.

See: newCapacitySpecification smart constructor.

Constructors

CapacitySpecification'

Fields

• readCapacityUnits :: Maybe Natural

  The throughput capacity specified for read operations defined in read capacity units (RCUs).

• writeCapacityUnits :: Maybe Natural

  The throughput capacity specified for write operations defined in write capacity units (WCUs).

• throughputMode :: ThroughputMode

  The read/write throughput capacity mode for a table. The options are:

  • throughputMode:PAY_PER_REQUEST and

  • throughputMode:PROVISIONED - Provisioned capacity mode requires readCapacityUnits and writeCapacityUnits as input.

  The default is throughput_mode:PAY_PER_REQUEST.

  For more information, see Read/write capacity modes in the Amazon Keyspaces Developer Guide.

Arguments

:: ThroughputMode

$sel:throughputMode:CapacitySpecification'

-> CapacitySpecification

Create a value of CapacitySpecification with all optional fields omitted.

Use generic-lens or optics to modify other optional fields.

The following record fields are available, with the corresponding lenses provided for backwards compatibility:

$sel:readCapacityUnits:CapacitySpecification', capacitySpecification_readCapacityUnits - The throughput capacity specified for read operations defined in read capacity units (RCUs).

$sel:writeCapacityUnits:CapacitySpecification', capacitySpecification_writeCapacityUnits - The throughput capacity specified for write operations defined in write capacity units (WCUs).

$sel:throughputMode:CapacitySpecification', capacitySpecification_throughputMode - The read/write throughput capacity mode for a table. The options are:

• throughputMode:PAY_PER_REQUEST and

• throughputMode:PROVISIONED - Provisioned capacity mode requires readCapacityUnits and writeCapacityUnits as input.

The default is throughput_mode:PAY_PER_REQUEST.

For more information, see Read/write capacity modes in the Amazon Keyspaces Developer Guide.

capacitySpecification_readCapacityUnits :: Lens' CapacitySpecification (Maybe Natural)

The throughput capacity specified for read operations defined in read capacity units (RCUs).

capacitySpecification_writeCapacityUnits :: Lens' CapacitySpecification (Maybe Natural)

The throughput capacity specified for write operations defined in write capacity units (WCUs).

capacitySpecification_throughputMode :: Lens' CapacitySpecification ThroughputMode

The read/write throughput capacity mode for a table. The options are:

• throughputMode:PAY_PER_REQUEST and

• throughputMode:PROVISIONED - Provisioned capacity mode requires readCapacityUnits and writeCapacityUnits as input.

The default is throughput_mode:PAY_PER_REQUEST.
