Queries the primary key of a table or a secondary index to directly access items from that table or index.
Command Syntax
table.query([indexName: string])
.whereKey(key: Object)
Where key is a pojo that represents the primary key for the item.
For the primary key, you must provide all of the attributes. For example, with a simple primary key, you only need to provide a value for the partition key. For a composite primary key, you must provide values for both the partition key and the sort key.
Usage
d.table('Movies')
.query([indexName])
.whereKey(keyCondition)
.filter() // filter condition to perform after the query has executed, but before the items are returned from DynamoDB
.pluck('year', 'title', 'rating') // optional. defaults to everything
.limit()
.run()
.then(data => {
console.log(data.Items); // Items will only have year, title, and rating attributes
});
