Dynamodb Gsi Partition Key Unique at Holly Kinross blog

Dynamodb Gsi Partition Key Unique. The primary key can consist of one attribute (the partition key), or two attributes (the partition and sort keys, jointly referred to as the composite key). Each item returned by the scan will have a unique partition key value. No items are needlessly read. If your table schema has only a partition key (no sort key), then generating a distinct list of partition keys can be done fairly efficiently using a table scan. Global secondary index (gsi)— an index with a partition key and a sort key that can be different from those on the base table. It is actually possible to ensure the uniqueness of a gsi by combining transactions and multiple tables. The only way to accomplish what you want efficiently in dynamo is to enable streams and have a lambda function that. For example, consider an orders table with customerid#productid#countrycode as the partition key and order_date as the sort key, where the symbol # is used to split different field. Try to combine more than one attribute to form a unique key, if that meets your access pattern. You might use such an. You could create a global secondary index with a partition key of topscore and a sort key of topscoredatetime. Lets say your main table has these.
