tCosmosDBBulkLoad Standard properties

A schema is a row description. It defines the number of fields (columns) to be processed and passed on to the next component. When you create a Spark Job, avoid the reserved word line when naming the fields.

Click Edit schema to make changes to the schema. If the current schema is of the Repository type, three options are available:

• View schema: choose this option to view the schema only.

• Change to built-in property: choose this option to change the schema to Built-in for local changes.

• Update repository connection: choose this option to change the schema stored in the repository and decide whether to propagate the changes to all the Jobs upon completion.

  If you just want to propagate the changes to the current Job, you can select No upon completion and choose this schema metadata again in the Repository Content window.

This check box appears when the File type you have selected is JSON.

  Note that when inserting data from CSV or TSV files into the MongoDB database, you need to specify fields either by selecting the First line is header check box or defining them in the schema.

• Upsert: Insert the data if they do not exist or update the existing data.

  Note that when upserting data into the MongoDB database, you need to specify a list of fields for the query portion of the upsert operation.

This table is available when you select Upsert from the Action on data list.
