data DynamoDBTarget

Specifies an Amazon DynamoDB table to crawl.

See: newDynamoDBTarget smart constructor.

DynamoDBTarget'

Fields

• path :: Maybe Text

  The name of the DynamoDB table to crawl.

• scanAll :: Maybe Bool

  Indicates whether to scan all the records, or to sample rows from the table. Scanning all the records can take a long time when the table is not a high throughput table.

  A value of true means to scan all records, while a value of false means to sample the records. If no value is specified, the value defaults to true.

• scanRate :: Maybe Double

  The percentage of the configured read capacity units to use by the Glue crawler. Read capacity units is a term defined by DynamoDB, and is a numeric value that acts as rate limiter for the number of reads that can be performed on that table per second.

  The valid values are null or a value between 0.1 to 1.5. A null value is used when user does not provide a value, and defaults to 0.5 of the configured Read Capacity Unit (for provisioned tables), or 0.25 of the max configured Read Capacity Unit (for tables using on-demand mode).

newDynamoDBTarget :: DynamoDBTarget

Create a value of DynamoDBTarget 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:path:DynamoDBTarget', dynamoDBTarget_path - The name of the DynamoDB table to crawl.

$sel:scanAll:DynamoDBTarget', dynamoDBTarget_scanAll - Indicates whether to scan all the records, or to sample rows from the table. Scanning all the records can take a long time when the table is not a high throughput table.

A value of true means to scan all records, while a value of false means to sample the records. If no value is specified, the value defaults to true.

$sel:scanRate:DynamoDBTarget', dynamoDBTarget_scanRate - The percentage of the configured read capacity units to use by the Glue crawler. Read capacity units is a term defined by DynamoDB, and is a numeric value that acts as rate limiter for the number of reads that can be performed on that table per second.

The valid values are null or a value between 0.1 to 1.5. A null value is used when user does not provide a value, and defaults to 0.5 of the configured Read Capacity Unit (for provisioned tables), or 0.25 of the max configured Read Capacity Unit (for tables using on-demand mode).

dynamoDBTarget_path :: Lens' DynamoDBTarget (Maybe Text)

The name of the DynamoDB table to crawl.

dynamoDBTarget_scanAll :: Lens' DynamoDBTarget (Maybe Bool)

Indicates whether to scan all the records, or to sample rows from the table. Scanning all the records can take a long time when the table is not a high throughput table.

A value of true means to scan all records, while a value of false means to sample the records. If no value is specified, the value defaults to true.

dynamoDBTarget_scanRate :: Lens' DynamoDBTarget (Maybe Double)

The percentage of the configured read capacity units to use by the Glue crawler. Read capacity units is a term defined by DynamoDB, and is a numeric value that acts as rate limiter for the number of reads that can be performed on that table per second.

The valid values are null or a value between 0.1 to 1.5. A null value is used when user does not provide a value, and defaults to 0.5 of the configured Read Capacity Unit (for provisioned tables), or 0.25 of the max configured Read Capacity Unit (for tables using on-demand mode).
