Summary
In this chapter, we delved into the world of secondary indexes in DynamoDB, exploring their significance in expanding the accessibility and efficiency of database queries. We began by understanding the evolution of secondary indexes, tracing their development from customer feedback to the introduction of both local and global secondary indexes.
LSIs emerged as a solution for scenarios where additional access patterns were required within the confines of the base table’s key schema. Their characteristics, including shared throughput and strong read-after-write consistency, made them valuable for specific use cases.
On the other hand, GSIs offered a more flexible alternative, allowing for independent throughput and storage management, catering to a diverse range of access patterns. Despite the presence of LSIs, GSIs became essential for supporting eventual consistency and accommodating complex querying requirements.
Throughout the discussion, we compared the strengths...
