Rework crawl page migration + MongoDB Query Optimizations (#2412)
Fixes #2406 

Converts migration 0042 to launch a background job (parallelized across
several pods) to migrate all crawls by optimizing their pages and
setting `version: 2` on the crawl when complete.

Also Optimizes MongoDB queries for better performance.

Migration Improvements:

- Add `isMigrating` and `version` fields to `BaseCrawl`
- Add new background job type to use in migration with accompanying
`migration_job.yaml` template that allows for parallelization
- Add new API endpoint to launch this crawl migration job, and ensure
that we have list and retry endpoints for superusers that work with
background jobs that aren't tied to a specific org
- Rework background job models and methods now that not all background
jobs are tied to a single org
- Ensure new crawls and uploads have `version` set to `2`
- Modify crawl and collection replay.json endpoints to only include
fields for replay optimization (`initialPages`, `pageQueryUrl`,
`preloadResources`) if all relevant crawls/uploads have `version` set to
`2`
- Remove `distinct` calls from migration pathways
- Consolidate collection recompute stats

Query Optimizations:
- Remove all uses of $group and $facet
- Optimize /replay.json endpoints to precompute preload_resources, avoid
fetching crawl list twice
- Optimize /collections endpoint by not fetching resources 
- Rename /urls -> /pageUrlCounts and avoid $group, instead sort with
index, either by seed + ts or by url to get top matches.
- Use $gte instead of $regex to get prefix matches on URL
- Use $text instead of $regex to get text search on title
- Remove total from /pages and /pageUrlCounts queries by not using
$facet
- frontend: only call /pageUrlCounts when dialog is opened.

  • It needs to update Helm charts after changing its dependencies (e.g. logging)
$ helm dependency update .

Update metacontroller

#!/bin/bash

# intall metacontroller
git clone --depth=1 https://github.com/metacontroller/metacontroller.git
cd metacontroller
helm package deploy/helm/metacontroller --destination deploy/helm
cd ..

# update dependency
helm dependency update
  • Bump up the metacontroller version in Chart.yaml
