Perform strongly consistent (http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/HowItWorks.ReadConsistency.html) read operations against this table. Note that there is no equivalent on table indexes as consistent reads from secondary indexes are not supported by DynamoDB

Value parameters
- exclusiveStartKey
-
A DynamoObject containing attributes that match the partition key and sort key of the table
Attributes
- Returns
-
A new Table which when queried will return items after the provided exclusive start key
- Example
-
import org.scanamo._ import org.scanamo.syntax._ val table: Table[_] = ??? val exclusiveStartKey = DynamoObject( Map( "myPartitionKeyName" -> myPartitionKeyValue.asDynamoValue, "mySortKeyName" -> mySortKeyValue.asDynamoValue ) ) val tableStartingFromExclusiveStartKey: Table[_] = table.from(exclusiveStartKey)
A secondary index on the table which can be scanned, or queried against
A secondary index on the table which can be scanned, or queried against

Query or scan a table, limiting the number of items evaluated by Dynamo

Attributes
Performs a query with the ability to introduce effects into the computation. This is useful for huge tables when you don't want to load the whole of it in memory, but scan it page by page.

To control how many maximum items to load at once, use queryPaginatedM
Attributes
Performs a scan with the ability to introduce effects into the computation. This is useful for huge tables when you don't want to load the whole of it in memory, but scan it page by page, with a maximum of pageSize items per page.

Attributes
- Note
-
DynamoDB will only ever return maximum 1MB of data per query, so
pageSizeis an upper bound.
Queries the table and returns the raw DynamoDB result. Sometimes, one might want to access metadata returned in the QueryResponse object, such as the last evaluated key for example. Table#query only returns a list of results, so there is no place for putting that information: this is where query0 comes in handy!

A particular use case is when one wants to paginate through result sets, say:
