Performance note
$everything
is a heavy operation that performs several SQL requests. If one of the request's duration is too long, the operation will fail due to timeout.
This can be fixed in two ways:
Add
_timeout=<n-seconds>
search parameter;Optimize the request by adding an index.
Here's the list of search parameters that Aidbox uses to find everything about the patient.
For example, we suspect, that $everything operation is slow because we have a lot of Observations. The internal search for Observations that refer Patient is:
It will be transformed into:
To debug this, we can query using _explain search parameter:
And now we see the SQL and the PostgreSQL plan:
The next step is to optimize the request.
