Springで大量データを処理する（にはどうすりゃいいの？(´・ω・｀)）

spring-boot
More than 1 year has passed since last update.

全く解決してないメモです＾ｐ＾

通常のJPARepositoryのInsertでは、
ときどき、メモリやコネクションプールがいっぱいになってしまい、
EntityManagerが落ちてしまう。

現在試行錯誤中。
考えられる解決策

・Spring-BatchでBatch処理を行う　←　最もスタンダードな解決法
・MyBatisでBatch処理を行う
・Hibernate、JPAを使ってBatchInsert ←　一番やりたい！
・コマンドプロンプトでバッチからBulkInsert ←　本番環境ではAPサーバーとDBサーバーが物理上離れている。
本番環境では実行できなさそう？・・・？
