Documentation

data DynamoDBTarget Source #

Specifies an Amazon DynamoDB table to crawl.

See: newDynamoDBTarget smart constructor.

Constructors

DynamoDBTarget'

Fields

path :: Maybe Text
The name of the DynamoDB table to crawl.
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).
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.

newDynamoDBTarget :: DynamoDBTarget Source #

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: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).

$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.

dynamoDBTarget_path :: Lens' DynamoDBTarget (Maybe Text) Source #

The name of the DynamoDB table to crawl.

dynamoDBTarget_scanRate :: Lens' DynamoDBTarget (Maybe Double) Source #

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_scanAll :: Lens' DynamoDBTarget (Maybe Bool) Source #

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.
