Ruby on Rails latest stable (v5.2.3) - 0 notes - Class: RecordFetchWarning
exec_queries() public

When this module is prepended to ActiveRecord::Relation and config.active_record.warn_on_records_fetched_greater_than is set to an integer, if the number of records a query returns is greater than the value of warn_on_records_fetched_greater_than, a warning is logged. This allows for the detection of queries that return a large number of records, which could cause memory bloat.

In most cases, fetching large number of records can be performed efficiently using the ActiveRecord::Batches methods. See ActiveRecord::Batches for more information.
