An Adobe Commerce developer needs to transform complex product data, which is stored in an EAV (Entity-Attribute-Value) structure, into flat tables for faster querying on the storefront. What is the…

Options

• ATo improve the performance of write operations in the Admin panel.
• BTo archive old product data into separate tables.

Explanation

Adobe Commerce's indexing system exists precisely to solve the read-performance problem caused by EAV storage: it pre-computes and flattens scattered EAV data into denormalized flat tables, so storefront queries retrieve product data in milliseconds instead of joining dozens of tables at runtime - making D correct.

Why the distractors fail:

• A is wrong because indexing is a read optimization, not a write optimization - it actually adds overhead to write operations since indexes must be rebuilt after data changes.
• B is wrong because archiving is a data lifecycle/retention concern, unrelated to the indexer's purpose of restructuring active data for performance.
• C is wrong because backups are a disaster-recovery mechanism; the indexer creates derived flat tables from the canonical EAV source, not copies for safety.

Memory tip: Think of the indexer as a "pre-answering machine" - it does the expensive work of joining EAV tables ahead of time and caches the result in a flat table, so the storefront just reads a ready-made answer instead of computing one on every page load.
