Morphium 6.1.0 - Release Summary

Quick Summary

Major feature release introducing MorphiumServer with replica set support, SSL/TLS for the server, snapshot persistence, significant InMemoryDriver improvements, and a comprehensive test infrastructure overhaul.

Highlights

MorphiumServer: Standalone MongoDB-Compatible Server

MorphiumServer is now a true drop-in replacement for MongoDB in development and testing:

• Replica set support with automatic primary election and failover (Raft-inspired protocol)
• SSL/TLS encrypted connections via Netty
• Snapshot persistence (--dump-dir, --dump-interval) for data survival across restarts
• Standalone CLI (morphium-server-cli.jar) for running from the command line
• Any MongoDB client (Java, Python, Node.js, Go, mongosh, Compass) can connect

# Start with persistence and SSL
java -jar target/morphium-6.2.0-SNAPSHOT-server-cli.jar \
  --port 27017 --dump-dir ./data --dump-interval 300 \
  --ssl --sslKeystore server.jks --sslKeystorePassword changeit

InMemoryDriver Enhancements

• Shared databases: Multiple Morphium instances can share the same InMemory database (setShareInMemoryDatabase(true))
• Full $text query support: MongoDB-compatible text search with phrase matching, negation, and case sensitivity
• Tailable cursor support
• Performance: Removed global synchronization, optimized find() deep copy, improved index lookups, $in O(n+m) via HashSet

Messaging Improvements

• Topic Registry / Network Registry for discovering messaging topics across the network
• MessagingSettings configuration class
• Various stability fixes for connection handling, message processing, and shutdown

Test Infrastructure Overhaul

• MultiDriverTestBase: 72 test classes migrated, 356+ methods now parameterized across drivers
• Driver selection: ./runtests.sh --driver inmem|pooled|all
• MorphiumServer backend: ./runtests.sh --morphium-server

Migration from 6.0.x

No breaking API changes. Key points:

1. MorphiumServer CLI JAR is a new build artifact (morphium-X.Y.Z-server-cli.jar)
2. Messaging settings moved to MorphiumConfig.messagingSettings()
3. InMemory shared databases are opt-in via DriverSettings.setShareInMemoryDatabase()

Requirements

• Java 21+
• MongoDB 5.0+ (for production deployments)
