RDM 14.5.3 Upgrade Notes

Changes to REST API JSON formatting

RDM REST API now uses standard JSON formatting:

Numeric and Boolean values no longer use quotation marks.
Datetime values use ISO datetime format.
Null values are represented as null (previously empty strings "").

Compare examples: the lef-hand side shows the old format (14.5.2 and earlier), the right-hand one shows the new format.

Configuration changelog

This section provides the information about the changes in the configuration files that need to be taken into account when upgrading the solution. In certain cases, the newly introduced default is used or some configuration is required.

The following table lists the changes in the files: added, changed, and removed properties.

Configuration file Added properties Changed properties Removed properties

application.properties

ataccama.one.rdm.api.response.default-count (Optional) - The default number of records returned in a single REST API request. To have more records returned, provide a new number in the request itself (must be lower than max-count). The default value is 30.
ataccama.one.rdm.api.response.max-count (Optional) - The maximum number of records that can be returned in a single REST API request. How many records are returned is defined in the count field of the filter parameter for each request (must be lower than max-count). Default value: 1000.

If the count parameter in a request exceeds the max-limit (default value 1000), this results in an HTTP 400 Bad Request response status code. For details, refer to RDM Application Properties.
