Expand description
Redis’s glob matching, which is what KEYS, SCAN MATCH, CONFIG GET and
COMMAND LIST FILTERBY PATTERN all mean by a pattern.
It is not a regular expression and it is not the shell’s glob either. There
are four things in it: * for any run of bytes, ? for one byte, [...]
for a class, and a backslash for the byte after it. Everything else is a
literal, including the bytes that are special in a regular expression, so
user.* matches user.1 and does not match userX1.
Bytes rather than characters, the same as Redis. A pattern is matched against a key, a key is arbitrary bytes, and deciding what a character is would mean deciding what encoding a key is in, which nobody can do.
