# Introduction
In this pull-request we introduce a service dedicated to the
twenty-standard app installation, we will later be able to re-use
existing logic to be more generic and allow any app installation.
For the moment sticking to this usage
https://github.com/twentyhq/core-team-issues/issues/1995
## Encountered issues
- We decided not to migrate deprecated fields ( also they will become
custom field for any existing workspace having them in the future )
- duplicate criteria
- wrong search index declaration
- forgotten isSearchable
- Attachement seed
- Restored standardId
## Note
For the moment we're still searching through standardId for code that
run on both existing and new workspaces.
For code running on new workspace exclusively we're searching using
universalIdentifier
We will standardize universalIdentifier usage later when we've migratred
all the existing workspaces
## Workspace creation
Will handle workspace creation the same way in another PR

## TODO
- [ ] Double all frontend hardcoded queries to not refer to deprecated
fields especially attachments
## Context
Deprecating the old objectMetadataMap type in favour of split flat
entities to match with our new caching.
In the long run, trying to achieve:
- Better performance through caching
- Consistent data access patterns across the codebase
- Reduced database queries
Now that everything is based on flat entities, which are cached, we can
finish the refactoring of workspace context cache which should already
improve performances.
Then the last step will be to consume that new cache in the new global
datasource to get rid of the many workspace datasources stored in the
server
Context :
Large PR with 600+ test files. Enable connect and disconnect logic in
createMany (upsert true) / updateOne / updateMany resolvers
- Add disconnect logic
- Gather disconnect and connect logic -> called relation nested queries
- Move logic to query builder (insert and update one) with a preparation
step in .set/.values and an execution step in .execute
- Add integration tests
Test :
- Test API call on updateMany, updateOne, createMany (upsert:true) with
connect/disconnect
