[data views] Move data views api from data plugin and into its own #113497

mattkime · 2021-09-30T03:57:00Z

Summary

Moving the data views api from the data plugin into its own plugin to shrink the data plugin bundle size and for better separation of concerns.

In order to minimize the impact of this change, the data plugin provides the data views api and re-exports data view exports. This should be removed once all api consumers are using the data view plugin directly.

Noticed couple issues that could be addressed:

src/plugins/data_views/jest.config.js

+  preset: '@kbn/test',
+  rootDir: '../../..',
+  roots: ['<rootDir>/src/plugins/data_views'],
+  testRunner: 'jasmine2',


could try to remove 'jasmine2' override here. maybe it would all pass with default runner

src/plugins/data_views/tsconfig.json

+    "server/**/*.json"
+  ],
+  "references": [
+    { "path": "../../core/tsconfig.json" },


Likely not all of these references needed for data_views plugin

I think the intention here is good, but I don't think splitting views out of the data plugins is actually helping. Splitting plugins is not a good way to separate concerns and the overall impact on initial page load bundles is +11kb. I think we should take another approach here.

I've misread the bundles info here. If the goal here was to reduce the overall bundles size, it actually did the opposite. Thanks @spalger for double checking this

Splitting plugins is not a good way to separate concerns

I'm confused by this in part because this PR is pretty clean meaning there was a relatively good separation of concerns to begin with. Having two plugins instead of one should encourage maintaining this separation. Is there an alternative approach you recommend?

and the overall impact on initial page load bundles is +11kb.

We have a goal to keep bundle sizes below 100kb but I'm unaware of any guidelines around limiting total payload growth, particularly around something as small as 11kb.

I haven't investigated it yet, but I suspect the additional 11kb is because the data plugin reexports most of the data views plugin exports. This is to limit the overall impact on the code base due to splitting plugins. That said, I suspect you have more experience thinking about these things - what overhead can we expect introducing a new plugin? How many kb?

I've misread the bundles info here. If the goal here was to reduce the overall bundles size, it actually did the opposite. Thanks @spalger for double checking this

No, the goal was to reduce the size of the data plugin, which it did. The goal was not to reduce overall bundle size - I would expect some amount of combined bundle size increase by separating plugins. This is 2% growth compared to the starting point. Its not desired but I don't understand why it would dissuade from moving forward with this.

Here's where we split out field formatters from the data plugin - #107173 - Page load bundle sizes grew by 14kb and more specifically a 11.7kb growth from data plugin including field formatters vs field formatters in its own plugin.

tylersmalley · 2021-10-04T14:49:41Z

@mattkime, the point of reducing plugin bundles is to reduce the overall page load. Details can be found in this issue: #95853

@mattkime and I have discussed this at length and agree that this doesn't meet the goal of improving page load time or reducing bundle sizes, but think that it ultimately is worth merging for the purpose of encapsulating the "data views" and eventually being able to move that into a package. I've agreed to work with the app services team and help consult on further efforts to reduce the size of the data plugin, which we really should be able to do.

We will prevent many data* plugins from being created and I think we can accept this 11.5kb debt for now.
