Other Capabilities

HVR supports the following capabilities on SingleStore:

• Both row store and column store tables can be created (SingleStore version 7.1).
• Use distribution key for parallelizing changes within a table (ColumnProperties with parameter DistributionKey) (SingleStore version 7.1).
• Call database procedure dbproc during replication jobs (AgentPlugin with parameter DbProc) (SingleStore version 7.1).
• International table and column names where DBMS is not configured with UTF-8 encoding (SingleStore version 7.1).

• Always treat DBMS schema names case sensitive (SingleStore version 7.1).

HVR does not support the following capabilities on SingleStore:

• Lossless binary float datatypes. No data loss when transporting float values (because base 2 fractions are never converted to base 10). The values for these datatypes, when selected back from the database, might be slightly different from the ones that were inserted. This leads to Compare differences..
