Logstash 7.2 Filters and filter plugins execution order

Elastic Stack Logstash
1

Hello all!

Please, expand the concise documentation.
What is the execution order which Logstash applies to many filters and their inner plugins?
For example, I have this in logstash.conf:

filter{
mutate1...
grok1...
}
filter{
grok2...
mutate2
}

What's the execution order?
Thank you very much.

They are executed in the order they appear in the file -- mutate1 followed by grok1 followed by grok2 followed by mutate2
