             Summary: Allow partial message read in JMAP DRAFT
                 Key: JAMES-2919
                 URL: https://issues.apache.org/jira/browse/JAMES-2919
             Project: James Server
          Issue Type: Wish
          Components: JMAP
            Reporter: Benoit Tellier
            Assignee: Antoine Duprat


Please find attached the two technical decisions being proposed.

# Objectives:

 - Reduce the pressure exerced by JMAP on underlying data stores
 - Improve network usage between James & JMAP client

## Proposal for JMAP partial reads

Introduce two projections for JMAP messages:
 - One with only metadata
 - One with metadata + headers

Given the properties requested by the client, the most appropriate message projection will be returned.

Finally, we should nullify JSON fields not requested by the client before sending it to the client.

## Proposal for JMAP preview computation

We should pre-compute message preview.

A MailboxListener will compute the preview and store it in a MessagePreviewStore.

We should have a Cassandra and memory implementation.

When the preview is precomputed then for these messages we can consider the "preview" property as a metadata.

We should provide a webAdmin task allowing to rebuild the projection.
