Index pattern field class refactor #73180

mattkime · 2020-07-24T03:20:05Z

Summary

Better distinction and relationship between IndexPatternField and its spec
IndexPatternField class is no longer defined via object mutation
Reduction of dependencies
UI code moved into Index Pattern class (will be removed in next ticket)
IndexPattern field list was previously composed of IndexPatternFields or specs, now only IndexPatternFields
IndexPattern field list was previously redefined when loading fields, now only its contents are replaced.

Checklist

Unit or functional tests were updated or added to match the most common scenarios

There seems to be a functional test failing related to this change. Other than that LGTM, checked on Mac/Ubuntu Chrome, all seems to be working.

src/plugins/data/common/index_patterns/fields/field_list.ts

-      this.groups.get(field.type)!.set(field.name, field);
-    };
-    private removeByGroup = (field: IFieldType) => this.groups.get(field.type)!.delete(field.name);
+export class FieldList extends Array<IndexPatternField> implements IIndexPatternFieldList {


I'm a bit concerned about extending the native Array here. Array has many public methods, are we sure we want to expose all of those as part of FieldList. If users use those, they can basically mutate the FieldList while by-passing the business logic of FieldList.

Maybe we could use composition instead?

class FieldList { private data: Array<IndexPatternField> = []; }

100% agree, but I'm avoiding changing the class interfaces in this PR. Will address in a follow up - #68020

-      specs.map((field) => this.add(field));
-    }
+  getByName = (name: IndexPatternField['name']) => this.byName.get(name);


All these could have readonly modifier.

Suggested change

getByName = (name: IndexPatternField['name']) => this.byName.get(name);

readonly getByName = (name: IndexPatternField['name']) => this.byName.get(name);

or

Suggested change

getByName = (name: IndexPatternField['name']) => this.byName.get(name);

public readonly getByName = (name: IndexPatternField['name']) => this.byName.get(name);

+    displayName: string,
+    onNotification: OnNotification
+  ) {
+    this.indexPattern = indexPattern;


i don't like the fact that we need to pass indexPattern in just to be able to get to formatter, could we:

remove format function and have consumers always use indexPattern.getFormatterForField(field) ?

or actually push that to the service, so we would do something like indexPatterns.getFormatter(indexPattern, field) and both IndexPattern and IndexPatternField get rid of that dependency (and can be static)

i am fine with doing this later, i am just wondering how reasonable you think that is ?

100% This PR keeps the class interfaces largely the same. My next PR will address this -#71909

I investigated the failing functional test in the transform plugin.

We use the Kibana index pattern field information to determine whether that field is suitable to be used for a preview visualization. Among other things we check against the aggregatable attribute.

On master, for the fields of the kibana e-commerce sample dataset we get the following:

name: category 	type: string 	aggregatable: false
name: currency 	type: string 	aggregatable: true
name: customer_birth_date 	type: date 	aggregatable: true
name: customer_first_name 	type: string 	aggregatable: false

When running this PR, we get:

name: category 	type: string 	aggregatable: undefined
name: currency 	type: string 	aggregatable: true
name: customer_birth_date 	type: date 	aggregatable: true
name: customer_first_name 	type: string 	aggregatable: undefined

Since in our code we do a strict equal check (field?.aggregatable === false) the code no longer works as expected.

The code causing this can be found here: https://github.com/elastic/kibana/blob/master/x-pack/plugins/ml/public/application/components/data_grid/common.ts#L157

Hope this helps, let me know if I can help out with more investigations.
