For years, a comment in EtchStore.java read: "Garbage collection is left as an exercise for the reader." We're finally doing the exercise. Coming in Convex 0.8.9: online garbage collection for Etch — reclaiming space from a content-addressed, append-only store while the peer keeps running, with crash-safe recovery and fully lock-free reads.

DLFS — the Decentralised Lattice File System — now supports sparse files up to 9.2 exabytes (Long.MAX_VALUE bytes). Creating one is instant. Writing a single byte into the middle takes microseconds. Here's how we made that work with a handful of elegant tricks in Convex's immutable data layer.

When your internal queue is full, you have two bad options: drop the message (making it the client's problem) or block the thread (making it your problem).

At Convex, we found a third way. We call it the Parking Ticket Pattern.

We're excited to announce comprehensive documentation for the Java SDK for Convex! Java developers can now build on the Convex decentralised lattice with native JVM performance and familiar Java patterns.

Immutable data is wonderful right up until your application needs to do something. Convex 0.8.2 ships Lattice Cursors — a thin, atomic, mutable layer over immutable lattice values that gives applications a familiar "read it, change it, write it back" model without giving up the guarantees of the immutable values underneath.
