Table
Represents a DynamoDB table that operations can be performed against
Value members
Concrete methods
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

Primes a search request with a key to start from:
- Value parameters:
- exclusiveStartKey
A DynamoObject containing attributes that match the partition key and sort key of the table
- 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

Query a table based on the hash key and optionally the range key

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
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.

page.
- 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:
Updates an attribute that is not part of the key and returns the updated row
