changeRequests

A list of change request objects that are run in order. A change request object consists of changeType , s3Path, and dbPath. A changeType can have the following values:

• PUT – Adds or updates files in a database.

• DELETE – Deletes files in a database.

All the change requests require a mandatory dbPath attribute that defines the path within the database directory. All database paths must start with a leading / and end with a trailing /. The s3Path attribute defines the s3 source file path and is required for a PUT change type. The s3path must end with a trailing / if it is a directory and must end without a trailing / if it is a file.

Here are few examples of how you can use the change request object:

• This request adds a single sym file at database root location. { "changeType": "PUT", "s3Path":"s3://bucket/db/sym", "dbPath":"/"}

• This request adds files in the given s3Path under the 2020.01.02 partition of the database.{ "changeType": "PUT", "s3Path":"s3://bucket/db/2020.01.02/", "dbPath":"/2020.01.02/"}

• This request adds files in the given s3Path under the taq table partition of the database.[ { "changeType": "PUT", "s3Path":"s3://bucket/db/2020.01.02/taq/", "dbPath":"/2020.01.02/taq/"}]

• This request deletes the 2020.01.02 partition of the database.[{ "changeType": "DELETE", "dbPath": "/2020.01.02/"} ]

• The DELETE request allows you to delete the existing files under the 2020.01.02 partition of the database, and the PUT request adds a new taq table under it.[ {"changeType": "DELETE", "dbPath":"/2020.01.02/"}, {"changeType": "PUT", "s3Path":"s3://bucket/db/2020.01.02/taq/", "dbPath":"/2020.01.02/taq/"}]
