Efficient Batch Loading of 10,000 Drupal Nodes for Performance

Drupal Life Hacks explains batch processing of 10,000 Drupal nodes using entityQuery with a .range(0,10000) limit and loadMultiple() in 500-node chunks. The article warns against loading nodes one-by-one or all at once to prevent performance degradation and memory issues. It presents two approaches:

1. EntityQuery + loadMultiple() for retrieving full node entities (titles plus custom fields).
2. Raw SQL queries on node_field_data for fast access to nid and title only.

Additional advice covers using Drupal’s Batch API for long operations, caching repeated queries, and choosing raw queries when only a few fields are needed. Code snippets illustrate both methods; however, no timing benchmarks or memory-usage metrics are provided.
