Kuzu V0 136 Fixed File

The release is not just a patch; it is a re-foundation. The three critical memory and concurrency bugs have been eradicated, performance has exceeded pre-regression levels, and the upgrade path is smooth for the vast majority of users. For any team currently stuck on v0.134 or suffering through v0.135, this update is mandatory.

However, version 0.135 introduced several regressions that hampered production use. The core issues ranged from race conditions in multi-threaded environments to a persistent segmentation fault when parsing certain data structures. The community has been eagerly awaiting a stable release, and with , those prayers have been answered. The Critical Bugs Addressed in Kuzu v0.136 Fixed The “fixed” tag in this release is not merely cosmetic. It represents a fundamental overhaul of three major subsystems. Below is a detailed look at the most impactful corrections. 1. The Memory Leak in the Buffer Pool (Issue #892) In v0.135, users reported linear memory growth during long-running operations. After 48 hours of continuous use, the Kuzu process would consume upwards of 12GB of RAM, eventually crashing the host system. The root cause was traced to a dangling pointer in the buffer pool’s eviction policy. Kuzu v0.136 fixed this by rewriting the LRU (Least Recently Used) cache eviction logic, introducing RAII (Resource Acquisition Is Initialization) guards. Early testing shows memory stabilization at under 2GB even after seven days of runtime. 2. Concurrent Write Corruption (Issue #901) Multi-threaded write operations were a nightmare in v0.135. Two threads writing to different segments of the same data structure would occasionally produce torn writes—half of one transaction, half of another. This led to silent data corruption, which is catastrophic for any database or stateful application. kuzu v0 136 fixed

reintroduces a recursive descent parser with enhanced stack overflow protection. The new parser handles arbitrarily deep JSON (tested up to 128 levels) and improves parsing speed by 18% compared to v0.134 (the last stable version). Additionally, error messages now include line and column numbers for malformed JSON, drastically improving debuggability. 4. Windows File Path Handling (Issue #915) Cross-platform users on Windows experienced a bizarre bug: Kuzu would fail to open any file with a space in its path (e.g., C:\My Data\kuzu.db ). The issue was an improper use of string escaping in the file URI handler. The kuzu v0.136 fixed patch replaces custom path logic with the standard std::filesystem::path class, ensuring full Unicode and whitespace support across Windows, Linux, and macOS. Performance Benchmarks: Before and After Numbers do not lie. The Kuzu team released a public benchmark comparing v0.135 (buggy) vs. v0.136 fixed on a standard dataset (TPC-H-like workload with 10 million records). However, version 0

In the fast-paced world of software development, few phrases bring as much relief to a user base as the words “fixed in the latest build.” For the community surrounding the Kuzu project—whether it be a lightweight embedded database, an emulation frontend, or a niche game engine—the rollout of Kuzu v0.136 fixed has been nothing short of a turning point.
