Task #1231
Updated by jortel@redhat.com about 9 years ago
Catalog model object: Unique Index (path, importer_id) plugin_id) Catalog: * path A unit storage path. * unit_id The content unit ID. * revision The revision is used to group entries into snapshots. * importer_id plugin_id An importer ID. ID * url The download URL * checksum The checksum used to verify downloaded file. Is: <algorithm>:<digest> * data Misc data (dict) used by the importer. The streamer will use only the latest revision of matching entries. Importers steps: 1. Create new entries using an incremented revision. 2. Remove all entries with older revisions. There may be another way of doing this but the goal is to ensure the streamer can use the catalog concurrently with it being updated without locking. And, that the catalog can be self-cleaning.
