Summary: I missed a stress test code sanity check when enabling this combination of tests. This PR addresses that, the "iter_start_ts" function for user defined timestamp feature is not supported when BlobDB is enabled. It's disabled for now. Pull Request resolved: https://github.com/facebook/rocksdb/pull/11199 Test Plan: Locally always enable BlobDB and run tools/db_crashtest.py --stress_cmd=./db_stress --cleanup_cmd='' --enable_ts whitebox --random_kill_odd 888887 Reviewed By: ltamasi Differential Revision: D43245657 Pulled By: jowlyzhang fbshipit-source-id: 4cae19817bb1afd50a76f9e0e49f006fb5c0b211
