Interface Table

All Known Implementing Classes:

ReTable

@Immutable
public interface Table

Amazon DynamoDB table abstraction.

To get data from the table use frame() method. To create a new item in the table (or replace the existing one) use Table#put(Attributes) method. For example:

 Region region = new Region.Simple(...);
 Table table = region.table("employees");
 table.put(new Attributes().with("name", "John Smith"));
 for (Item item : table.frame()) {
   System.out.println("Name: " + item.get("name").getS());
 }
 table.frame()
   .where("name", Conditions.equalTo("John Smith"))
   .iterator().next().remove();
