Properties
| Name | Type | Description |
|---|---|---|
| path? | string | The name of the DynamoDB table to crawl. |
| scan | boolean | IResolvable | Indicates whether to scan all the records, or to sample rows from the table. |
| scan | number | The percentage of the configured read capacity units to use by the AWS Glue crawler. |
path?
Type:
string
(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).
