When importing data into a CRDB, there are two options:

  • Perform a flushall to the database, thus deleting all data. Then import the data into the CRDB.
  • Import data but merge it into the existing or add new data from the import file.

When using option #2, there are special considerations to be aware of. Unlike a traditional Redis database, CRDBs have a numeric counter data type and thus require special ways to increment. The import through the Redis Enterprise web UI handles these data types for you. When you import data into a CRDB, there will be a special prompt such as the below.

As part of the import in the UI, RS will increment counters by the value that is in the importing data.
