 Public API for creating, updating, reading and querying primary data stored in the TRAC platform.
 The TRAC data API provides a standard mechanism for client applications to store and access data
 in the TRAC platform. Calls are translated into the underlying storage mechanisms, using push-down
 operations where possible for efficient queries on large datasets.
 The data API includes format translation, so data can be uploaded and retrieved in any supported
 format. The back-end storage format is controlled by the platform. For example if a user uploads
 a CSV file TRAC will convert it to the default storage format (by default Arrow IPC file format).
 Later a web application might ask for that data in JSON format and TRAC would again perform the
 conversion. The platform uses Apache Arrow as an intermediate representation that other formats
 are converted from and to.
 The data API uses streaming operations to support transfer of large datasets and can be used for
 both user-facing client applications and system-to-system integration. For regular, high-volume
 data transfers there are other options for integration, including data import jobs and direct
 back-end integration of the underlying storage technologies. These options can be faster and
 reduce storage requirements, at the expense of tighter coupling between systems. A compromise is
 to use direct integration and import jobs for a small number of critical feeds containing a
 high volume of data, and use the data API for client access and for integration of secondary
 and/or low-volume systems.
