Overview
activerecord-import adds bulk import APIs to ActiveRecord. It can insert model arrays, hashes, or column/value arrays in a small number of statements with batching, validation, duplicate-key handling, and PostgreSQL recursive association imports. The current version is 2.3.0.

Key features
Collapse many record inserts into one or a few SQL statements
Model.import can bulk-insert many records instead of issuing one INSERT per save. batch_size controls statement size and progress callbacks can report long-running imports.

Choose validation, upsert behavior, and PostgreSQL recursive imports
Projects can enable or skip validations, track failures, use database-specific upsert behavior, and recursively import associations on PostgreSQL.
Sources: [2]
Best fit
Fits large seeds, ETL, batch synchronization, and bulk upsert work that should stay close to ActiveRecord
It is useful when Rails batch jobs or data migrations need high-volume writes without replacing model-oriented code with fully hand-written SQL.

Before adoption
Understand callback and uniqueness-validation differences from normal ActiveRecord saves
Create, update, and destroy callbacks do not run exactly as they do with normal save, and uniqueness validation is disabled by default because enabling it can produce one query per record. Version 2.3.0 declares Ruby 2.4+ and ActiveRecord 4.2+ and adds compatibility work for newer Rails and multi-database connections.

Supplemental curator note
It can dramatically reduce insert statements while staying within ActiveRecord, but callbacks and uniqueness validation differ from normal saves. Validate those behavioral differences as well as throughput.
