Properties

The name of the DynamoDB table to crawl.

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.

Required: No

Type: Boolean

Update requires: No interruption

ScanRate

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

Required: No

Type: Number

Update requires: No interruption
