Question: What are the naming conventions in DynamoDB?
In DynamoDB, the naming conventions for tables, primary keys, and secondary indexes are as follows:
Table names: Must be unique within your AWS account and can contain only alphanumeric characters and underscores. The maximum length is 255 characters.
Primary key: The primary key is used to identify each item in a table uniquely and can be either a simple primary key (also known as a partition key) or a composite primary key (consisting of a partition key and a sort key).
Partition key: This must be unique within each partition and can contain any string or number.
Sort key: Can be used to sort items within a partition and contain any string or number.
Secondary indexes: Allow you to create additional indexes on a table that can be either global or local.
Global secondary index: This can have a different partition key and sort key than the primary key and can be created on any table.
Local secondary index: Must have the same partition key as the primary key but can have a different sort key.
