• In SensorCommon.java, making getRevisionFromResult() public to support usage in the sensor workload.
• Minor error message text updates in SensorChecker.java and schema updates in tx_sensor.cql to add a new keyspace and table.

• Since getRevisionFromResult is now part of the public API, consider adding JavaDoc to clarify its expected input, behavior, and any potential exceptions.

public static int getRevisionFromResult(Result result) {

• [nitpick] Consider removing the extra space before the exclamation mark for a cleaner error message.

logError("Duplication happened !");

• Consider updating the project schema documentation to include the new keyspace and table definitions added in this PR.
