ch can now delete - Model.delete_all leads to error: delete is not supported

[Georg Leciejewski]

See the clickhouse docs for delete

I'll see if i can fix that in my fork.

This is experimental function

uups, yes just stumbled into this error msg:

Lightweight delete mutate is experimental. Setallow_experimental_lightweight_delete setting to enable it

Still diving into the details of CH, wonder how to get rid of the data without ALTER table

You can use https://clickhouse.com/docs/en/engines/table-engines/mergetree-family/collapsingmergetree/ or https://clickhouse.com/docs/en/engines/table-engines/mergetree-family/replacingmergetree

[Georg Leciejewski]

Thanks for the hint, i'll dive into it!

[Brooke McKim]

@PNixx this is no longer experimental as of 23.3.

[Sergey Odintsov]

Thanks, I'll check it
