      • countOlderThan

        @Query("SELECT COUNT(*) FROM diagnosis_key WHERE submission_timestamp<:threshold")
int countOlderThan​(@Param("threshold")
                   long submissionTimestamp)
        Counts all entries that have a submission timestamp less or equal than the specified one.
        Parameters:
        submissionTimestamp - The submission timestamp up to which entries will be expired.
        Returns:
        The number of expired keys.

      • deleteOlderThan

        @Modifying
@Query("DELETE FROM diagnosis_key WHERE submission_timestamp<:threshold")
void deleteOlderThan​(@Param("threshold")
                     long submissionTimestamp)
        Deletes all entries that have a submission timestamp less or equal than the specified one.
        Parameters:
        submissionTimestamp - The submission timestamp up to which entries will be deleted.

      • saveDoNothingOnConflict

        @Modifying
@Query("INSERT INTO diagnosis_key (key_data, rolling_start_interval_number, rolling_period, submission_timestamp, transmission_risk_level) VALUES (:keyData, :rollingStartIntervalNumber, :rollingPeriod, :submissionTimestamp, :transmissionRisk) ON CONFLICT DO NOTHING")
boolean saveDoNothingOnConflict​(@Param("keyData")
                                byte[] keyData,
                                @Param("rollingStartIntervalNumber")
                                int rollingStartIntervalNumber,
                                @Param("rollingPeriod")
                                int rollingPeriod,
                                @Param("submissionTimestamp")
                                long submissionTimestamp,
                                @Param("transmissionRisk")
                                int transmissionRisk)
        Attempts to write the specified diagnosis key information into the database. If a row with the specified key data already exists, no data is inserted.
        Parameters:
        keyData - The key data of the diagnosis key.
        rollingStartIntervalNumber - The rolling start interval number of the diagnosis key.
        rollingPeriod - The rolling period of the diagnosis key.
        submissionTimestamp - The submission timestamp of the diagnosis key.
        transmissionRisk - The transmission risk level of the diagnosis key.
        Returns:
        true if the diagnosis key was inserted successfully, false otherwise.
