File: /master/basic-features.md

In this page There is a link to https://docs.pingcap.com/tidb/dev/sql-statement-alter-table that says "DDL algorithm assertions" .
I am not clear what "DDL algorithm assertions" actually means.

@morgo Can you take a look?
"DDL algorithm assertions" was first introduced in #6130

[morgo]

It's this syntax:

ALGORITHM=INPLACE, LOCK=NONE;

Thanks for the answer. Still I do not get what "assertion" intends here.

I'm thinking about changing this document link name from
"Online DDL" or "ALTER TABLE"?
