# Which Problems Are Solved
This PR introduces the possibility of using the relational DB when
calling the ListSession gRPC endpoint.
# How the Problems Are Solved
- Implement the Querier interface for ListSession:
- Create a `domain` model for the Session object to be able to map the
gRPC session into it.
- Match the permission filters on ES side to be sure the same sessions
are returned
- Implement converter methods to go from `gRPC` to `domain` models (both
ways)
- Fix the session sql relational migration: rework the trigger to update
the `expiration` field to perform the update only when the input
`lifetime` has a non-zero value.
- Link the Querier implementation with the gRPC endpoint
- Run the same integration tests against the relational DB, making sure
the outcome is the same. ⚠️ Due to missing permission checks, some
divergence is expected. Hence, specific code to circumvent the
differences has been put in place
# Additional Context
- Closes#11039
# Which Problems Are Solved
As part of moving the session API to the relational database, this PR
adds the functionality to delete sessions through the session API v2 and
the OIDC end_session endpoint.
# How the Problems Are Solved
- added `SessionDeleteCommand` in domain package
- added possibility to pass the session token verifier to the domain
package
- use feature flag to switch API and OIDC usage from CQRS to relation
table
- added a `permissionCheck` condition to let permissions be checked
directly in the repository / sql
- part of it is still a placeholder until actual permission tables are
done
- added a `session_deleted` table to store (recently) deleted sessions
to handle necessary checks / cases like delete my own session, which
needs to be idempotent
# Additional Changes
Fixed `Matches` function of `existsCondition` (as missing an
implementation)
# Additional Context
- closes#11037
