- Sink compaction frontier possibly incorrect
-
tracing::errorshould "panic" in CI - Introspection sources/views across replicas
- [compute] Instances should be able to operate efficiently on data that exceeds RAM
- [storage] Logging only started by compute instance initialization
-
Separate
mz_dataflowintomz_storageandmz_compute - [storage] MZ's serialized order should match the order of external source events
- [EPIC] Transactions in Materialize are strictly serializable with respect to the operations that occur inside of Materialize.
- Monitor read and write frontiers for all Compute collections
- Monitor and report Active Replica health
- Generalize applicability of temporal filters
-
Sinks do not all populate
sink_write_frontiersand thereby prevent compaction
