Condition database includes non-event-related information (Alignment, Calibration, Temperature, etc.) and parameters for simulation/reconstruction/analysis software.
These files are needed when running a CMSSW job on the open data environment (VM or container), and they are available in the /cvmfs/cms-opendata-conddb.cern.ch file system. They are automatically read from /cvmfs/cms-opendata-conddb.cern.ch/FT_R_42_V10A runtime.
FT_R_42_V10A is to be used with the collision data of RunA 2010.
See further information in the guide to CMS condition database.
