Add an account key field to improve search performance. This field
allows us to filter the records by account directly in the fulltext
index, so we only need to examine rows belonging to the relevant account.
Lean on ActiveRecord models for searching and strip out the raw SQL.
Replaces the search_index_* tables with sharded search_records_* tables
as that allows us to use a Search::Record model name.
A Class is dynamically created for each record table shard so that we
and we can access it via the Search::Record.for_account(account_id)
method.
Schema:
- add account_id to tables it was missing from
- make account_id a required column everywhere
- add [account_id] indexes, or add `account_id` to existing indices
Models:
- add `belongs_to :account` to all models (default to using a domain
model's account whenever possible)
- add account_id in all the necessary fixtures
- add account_id to insert_all hashes
- pass account_id to a few initialize calls
Miscellaneous:
- update the import script to set account_id
Note that I'm not adding account_id to the join tables primarily
because I couldn't think of an easy way to populate it without making
it a full Join model, and that was more work than I have time to take
on right now.
- Switch to binary 16 for UUID keys
- Remove AccountScopedRecord base class, all model use binary uuids now
- Fix the search sql to serialize uuids properly
- Patch the MySQL schema dumper to output binary lengths
