HarperDB Headers

All HarperDB API responses include headers that are important for interoperability and debugging purposes. The following headers are returned with all HarperDB API responses:

Key
Example Value
Description

server-timing

db;dur=7.165

This reports the duration of the operation, in milliseconds. This follows the standard for Server-Timing and can be consumed by network monitoring tools.

hdb-response-time

7.165

This is the legacy header for reporting response time. It is deprecated and will be removed in 4.2.

content-type

application/json

This reports the MIME type of the returned content, which is negotiated based on the requested content type in the Accept header.
