Example

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import { aws_glue as glue } from '@aws-cdk/cfn-property-mixins';
const dynamoDBTargetProperty: glue.CfnCrawlerPropsMixin.DynamoDBTargetProperty = {
  path: 'path',
  scanAll: false,
  scanRate: 123,

Properties

Name	Type	Description
path?	`string \|` `ITableRef`	The name of the DynamoDB table to crawl.
scanAll?	`boolean \|` `IResolvable`	Indicates whether to scan all the records, or to sample rows from the table.
scanRate?	`number`	The percentage of the configured read capacity units to use by the AWS Glue crawler.

path?

Type: string | ITableRef (optional)

The name of the DynamoDB table to crawl.

scanAll?

Type: boolean | IResolvable (optional)

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?

Type: number (optional)

The percentage of the configured read capacity units to use by the AWS 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).
