It's located in the .hoodie/hoodie.properties file, you can build the table meta client and fetch it through the table config.

Hi @njalan

In order to get the primary key, pre-combined key or partition key we need to read the <$TABLE_PATH>/.hoodie/hoodie.properties file.

Example:

hoodie.table.precombine.field=comb
hoodie.table.partition.fields=par
hoodie.table.recordkey.fields=id

Please let me know if any other information is required.
