# Which Problems Are Solved
If the processing time of serializable transactions in the fields
handler take too long, the next iteration can fail.
# How the Problems Are Solved
Changed the isolation level of the current states query to Read Commited
# Which Problems Are Solved
To improve performance a new table and method is implemented on
eventstore. The goal of this table is to index searchable fields on
command side to use it on command and query side.
The table allows to store one primitive value (numeric, text) per row.
The eventstore framework is extended by the `Search`-method which allows
to search for objects.
The `Command`-interface is extended by the `SearchOperations()`-method
which does manipulate the the `search`-table.
# How the Problems Are Solved
This PR adds the capability of improving performance for command and
query side by using the `Search`-method of the eventstore instead of
using one of the `Filter`-methods.
# Open Tasks
- [x] Add feature flag
- [x] Unit tests
- [ ] ~~Benchmarks if needed~~
- [x] Ensure no behavior change
- [x] Add setup step to fill table with current data
- [x] Add projection which ensures data added between setup and start of
the new version are also added to the table
# Additional Changes
The `Search`-method is currently used by `ProjectGrant`-command side.
# Additional Context
- Closes https://github.com/zitadel/zitadel/issues/8094
