I'd be happy to change this behaviour so if you pass `alter=True` and then use `.insert_all()` on more than 100 rows it works as you would expect, instead of silently ignoring new columns past the first 100 rows. I don't expect that anyone would be depending on the current behaviour (ignore new columns after the first 100) such that this should be considered a backwards incompatible change.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",686978131,

> If you have more than one record to insert, the insert_all() method is a much more efficient way of inserting them. Just like insert() it will automatically detect the columns that should be created, but it will inspect the first batch of 100 items to help decide what those column types should be.
