Techniques are provided for read-based storage of time-series records. In one example, a server obtains at least one indication of one or more records of a plurality of records written to a record database by a producer that have been read from the record database by at least one consumer. The server stores in a time-series database the one or more records that have been read by the at least one consumer. One or more records of the plurality of records that have not been read by the at least one consumer may be pruned from storage in the time-series database.
