From 0908184e4c2dca5b941030bbd0d5eb2dfcfed120 Mon Sep 17 00:00:00 2001 From: Ryuta Kamizono Date: Thu, 4 Apr 2019 03:19:08 +0900 Subject: Use `execute_batch2` rather than `execute_batch` to fix performance regression for fixture loading d8d6bd5 makes fixture loading to bulk statements by using `execute_batch` for sqlite3 adapter. But `execute_batch` is slower and it caused the performance regression for fixture loading. In sqlite3 1.4.0, it have new batch method `execute_batch2`. I've confirmed `execute_batch2` is extremely faster than `execute_batch`. So I think it is worth to upgrade sqlite3 to 1.4.0 to use that method.
