Morphium 6.2.6: The Timeout That Multiplied Itself by 100

Morphium 6.2.6 is out — and it repairs something that should never have been broken in the first place: replicaset failover. A chain of bugs (chief among them a timeout that silently multiplied itself by 100) meant the driver practically never recovered after the primary died: writes hung, messaging stayed dead. After the fixes: full write throughput ~25 seconds after a kill -9, no lost messages. Also on board: a fix for `findOneAndUpdate` deleting documents instead of updating them on read-cache hits, a self-deadlock in the SingleMongoConnectDriver, and `$setOnInsert`/upsert support in the InMemoryDriver.

Morphium 6.2.5: The One-Document Batch That Cost 20 Seconds

Morphium 6.2.5 is out. A quiet patch release with one loud story: a hardcoded change stream `batchSize=1` that turned into 20-second latency spikes over a high-latency link — plus Atlas TXT seedlist support, Quarkus native-image pre-registration, and a batch of InMemoryDriver and aggregation fixes.

Morphium 6.2.4 — When Messaging Dies Quietly

Morphium 6.2.4 is out. The reason behind it was a bug that took longer to find than to fix. In production, messaging suddenly stopped. The backlog grew. The log said nothing. Only the 10-second fallback poll kept the application half-alive. This is what we learned about producer/consumer architecture, silent `Error`s, and the hard 16 MB BSON limit, and the five layers of protection that came out of it.

Morphium v6 Performance — MongoDB vs PoppyDB vs InMemory

Morphium v6 rewrote the connection pool and messaging system from scratch. Here are the numbers: 38% more throughput, 2.5x faster messaging with PoppyDB, and a test suite that runs 879 tests across 5 backends in under an hour. --- id: 10647 ---

Morphium 6.2.2 — Bugfix Release with PoppyDB Hardening and Performance

Morphium 6.2.2 is here — a focused bugfix release that makes PoppyDB significantly more stable. Wire protocol corruption, thread leaks with 20,000 threads per node, and Raft election flapping are fixed. Plus: 4.7x faster startup via ClassGraph caching and PoppyDB is now 3x faster than MongoDB for individual operations.

Morphium 6.2.1 — A Bugfix Release That Packs a Punch

Morphium 6.2.1 is out — and while it's officially a bugfix release, there's considerably more inside than the version number suggests. ByteBuddy replaces spring-cglib, PoppyDB gets a stability overhaul, and the wire protocol is now much more robust against connection chaos.
