## Summary
- **Split the `rolesPermissions` cache query into parallel queries** to
eliminate a 5-way LEFT JOIN cartesian product. A workspace with a role
having 5 objectPermissions × 4 permissionFlags × 124 fieldPermissions ×
5 RLP predicates × 5 RLP groups was returning 62,000 rows from just ~162
distinct records, causing 10s+ query timeouts on view updates.
- **Added missing `roleId` index on `permissionFlag` table** — the only
permission table without one, which was causing sequential scans on the
JOIN.
Migrating some 1.21 migrations to the new pattern so it writes in the
history
When release in prod we will ahve to manually inject them as they have
already been run
It's mainly for self host so when releasing the 1.22 we will be able to
rely on the 1.21 history
# Introduction
Now only using typeorm to generate migrations up and down statement
We handle and maintain our own migration table history
## What's new
Now all the instance commands will live within the same module and
folder than the upgrade commands
Sequentiality comes from the timestamp located in the filename
Same sequentiality also applies to the workspace commands in the future,
for the moment still expected a as code explicit declaration
( below screen is an example see below section )

## Existing 1.21 migrations
We won't start following this pattern in 1.21 yet at least not with the
migration that has already been released as typeorm migrations in cloud
production as they would rerun
## Small duplication
Duplicating the legacy typeorm and instance commands run in the
`run-instance-commands` to avoid any merge of interest for the moment
## Concurrency
Not handling any run in parrallel of the upgrade for the moment
