Meta task to get my thoughts in order about adding a Cassandra backend to swh-storage. (Started in april)
[ ] have a draft implementation https://forge.softwareheritage.org/source/swh-storage-cassandra/
[x] benchmark to check the performances are not catastrophic https://forge.softwareheritage.org/source/storage-benchmark-deployment/
[x] increase test coverage of all behaviors of swh-storage (D 1534 to 1552)
[ ] numeric origin ids
[x] define a replacement T1731
[ ] get rid of numeric origin ids in all storage clients T1816
[ ] ~~public API v2 T1805~~ (postponed)
[ ] Add the draft Cassandra backend to the docker env (done with an earlier version, but not the current one)
[ ] Run the draft Cassandra backend with production data
[ ] Rewrite the Cassandra backend using the experience learned working on the draft
[ ] Add it to the docker env
[ ] Write a storage proxy component, that queries two backends and compares their results, to check they are the same; and run it in the docker env
[ ] Run it with production data
[ ] Deploy in production (possibly with the proxy at first)
