We’re happy to announce that Lagom 1.2.0-RC2 has been released!
This release has a small reworking of the read side event tags so that events can be automatically sharded by Lagom. Previously, your
aggregateTag function had to compute it’s own sharded tags if you wanted to shard your read sides. Now, you can simply return a single meta tag to say that the events should be sharded, and how many shards you want, and Lagom will handle the sharding for you. Read the documentation for more details.
We’ve also made some minor improvements around how Kafka message keys are extracted from messages, and provided topic testing support in the testkit.
On the documentation side, there’s more documentation for using and testing Kafka, and most importantly, we’ve written a migration guide, outlining any changes you may need to make in order to move from Lagom 1.1 to Lagom 1.2.
Lagom 1.2.0 should be released very soon, so stay tuned!
