Good morning.
So I'm into logstash filters code which contains tens of similar if conditionals like following:
```auto
if ("123456" == [ID]) {
mutate {
add_field => {
"[fields][key1]" => "value1"
"[fields][key2]" => "value2"
}
}
}
```
I was thinking about using ruby and array of hashes:
hashes = [
{"ID" =\> "123456", "key1" =\> "value1", "key2" =\> "value2"},
{"ID" =\> "234567", "key1" =\> "value1", "key2" =\> "value2"},
{"ID" =\> "345678", "key1" =\> "value1", "key2" =\> "value2"},
and so on ]
Is this a good approach and if it could I get any tips or links how to achieve that? Or if I took the wrong path could I get any advice how can achive my goal which is replacing tens if similar conditions with some friendly code?

You could use a translate filter. [This](https://discuss.elastic.co/t/logstash-how-to-configure-csv-filter-for-joining-2-csv-files-based-on-a-common-field-mapping-one-to-many-data-and-ingest-the-data-into-single-index/259994/2) has an example that might help.
