Method Details

getPath

@Stability(Stable)
@Nullable
default String getPath()

The name of the DynamoDB table to crawl.

• http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-glue-crawler-dynamodbtarget.html#cfn-glue-crawler-dynamodbtarget-path

getScanAll

@Stability(Stable)
@Nullable
default Object getScanAll()

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 .

• http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-glue-crawler-dynamodbtarget.html#cfn-glue-crawler-dynamodbtarget-scanall

getScanRate

@Stability(Stable)
@Nullable
default Number getScanRate()

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).

builder

@Stability(Stable)
static CfnCrawler.DynamoDBTargetProperty.Builder builder()

Returns:

a CfnCrawler.DynamoDBTargetProperty.Builder of CfnCrawler.DynamoDBTargetProperty
