As the topic suggests,
if the upstream table has 10 fields but the downstream only uses 2 fields, is it possible to synchronize only those 2 fields?
As far as I know, DM does not have a column pruning feature. To achieve this requirement, you can try using the dumpling/lighting tools, combined with the --snapshot parameter, to create a tool with ETL functionality.
DM does not yet have the function to filter fields, only to filter tables.
No, dear, the minimum dimension for DM synchronization is the table.
