Method: OccamsRecord::Query#find_in_batches

Defined in:
lib/occams-record/query.rb

#find_in_batches(batch_size: 1000, use_transaction: true, append_order_by: nil) {|OccamsRecord::Results::Row| ... } ⇒ Enumerator

Load records in batches of N and yield each batch to a block if given. If no block is given, returns an Enumerator.

NOTE Unlike ActiveRecord’s find_each, ORDER BY is respected. The primary key will be appended to the ORDER BY clause to help ensure consistent batches. Additionally, it will be run inside of a transaction.

Yields:
