Specifies an Amazon DynamoDB table to crawl.
Example
ts
// 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-lib';
const dynamoDBTargetProperty: glue.CfnCrawler.DynamoDBTargetProperty = {
path: 'path',
scanAll: false,
scanRate: 123,
};
Properties
The name of the DynamoDB table to crawl.
scanAlloptionalboolean | IResolvablescan_alloptionaltyping.Union[bool, IResolvable]scanAlloptionalBooleanScanAlloptionalboolScanAlloptionalinterface{}#Indicates whether to scan all the records, or to sample rows from the table.
notes
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 .
scanRateoptionalnumberscan_rateoptionalint | floatscanRateoptionalNumberScanRateoptionaldoubleScanRateoptional*float64#The percentage of the configured read capacity units to use by the AWS Glue crawler.
notes
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).
