Document ability to export raw clickhouse data via cube proxy
Context
As part of Spike: Determine implementation plan for produc... (#384944 - closed) we have determined that the most boring solution to allow users to export raw event data from clickhouse is to document the process by which to do that using existing tools and to add documentation to that effect.
Implementation
Add documentation to instruct users on how to contruct a cube proxy request that outputs a list of dimensions from the TrackedEvents
cube.
This should include a list of caveats such as:
- This method may not work beyond a certain number of events due to buffer limits or timeouts. (Yet to be tested.)
- Pagination needs to be implementation by the consumer using
LIMIT
statements. - Data is returned in JSON format, not CSV. Any data format modifications are the responsibility of the consumer.
- This is a temporary method until we implement background workers to upload clickhouse exports to object storage.
