This sum type models:
This sum type models:
- partition key equality expressions
- composite primary key expressions where sort key expression is equality
- extended composite primary key expressions where sort key is not equality eg >, <, >=, <=, between, begins_with
Note 1), 2) and 3) are all valid key condition expressions used in Query DynamoDB queries BUT only 1) and 2) are valid primary key expressions that can be used in GetItem, UpdateItem and DeleteItem DynamoDB queries

A Fake implementation of DynamoDBExecutor.Service that currently has the very modest aspiration of providing bare minimum functionality to enable internal unit tests and to enable simple end to end examples that can serve as documentation. Limited CRUD functionality is supported hence some features are currently not supported or have restrictions.
A Fake implementation of DynamoDBExecutor.Service that currently has the very modest aspiration of providing bare minimum functionality to enable internal unit tests and to enable simple end to end examples that can serve as documentation. Limited CRUD functionality is supported hence some features are currently not supported or have restrictions.
- Supported
- CRUD operations GetItem, PutItem, DeleteItem, BatchGetItem, BatchWriteItem
- Limited support
- Primary Keys - only the partition key can be specified and is only checked for equality
- Not currently supported
- Projections - all fields are returned for all queries
- Expressions - these include
KeyConditionExpression's,ConditionExpression's,ProjectionExpression's,UpdateExpression's - Create table, Delete table
- UpdateItem - this is a more complex case as it uses an expression to specify the update
- Indexes in ScanSome, ScanAll, QuerySome, QueryAll
'''Usage''': DynamoDBExecutor.test provides you the test DB instance in a ZLayer. Tables are created using the addTable method in the test controller service TestDynamoDBExecutor. You specify a table, a single primary and a var arg list of primary key/item pairs.
testM("getItem") {
for {
_ <- TestDynamoDBExecutor.addTable("tableName1", primaryKeyFieldName = "k1", primaryKey1 -> item1, primaryKey1_2 -> item1_2)
result <- GetItem(key = primaryKey1, tableName = tableName1).execute
expected = Some(item1)
} yield assert(result)(equalTo(expected))
}.provideLayer(DynamoDBExecutor.test)

Concrete methods
Reads stream using function pk to determine the primary key which is then used to create a BatchGetItem request. Stream is batched into groups of 100 items in a BatchGetItem and executed using the provided DynamoDBExecutor service Returns a tuple of (A, Option[B]) where the option is None if the item is not found - this enables "LEFT outer join" like functionality
