Nippyspace - Alternative

Excellent for communities collaborating on direct projects or live streams.

NippySpace functions by mapping a single file into the virtual address space. It uses a B+tree structure where data is organized into pages. To ensure atomicity, it employs a copy-on-write strategy: modifying a page creates a new copy of that page and its ancestors up to the root. nippyspace alternative

The proliferation of microservices and high-frequency trading applications has necessitated key-value stores that operate with microsecond latency. NippySpace, a popular implementation utilizing memory-mapped files (MMAP) and BoltDB-like structures, offers transactional consistency but suffers from performance degradation under high write loads due to "stop-the-world" garbage collection and page fragmentation. This paper introduces VelocityStore , a proposed alternative architecture. VelocityStore replaces the MMAP-based copy-on-write B-tree with a shard-based, log-structured merge-tree (LSM) approach combined with an optimized jemalloc-backed arena allocator. We demonstrate that VelocityStore reduces tail latency by 40% and improves write throughput by 60% compared to NippySpace, while maintaining AES-256-GCM encryption standards for data at rest in memory. To ensure atomicity, it employs a copy-on-write strategy:

NippySpace encrypts pages, which complicates random access. VelocityStore utilizes . Each record in the Arena is encrypted individually using AES-256-GCM. The nonce is stored adjacent to the ciphertext in the Arena. While this slightly increases storage overhead (due to authentication tags per record), it allows for independent decryption of records without decrypting an entire memory page, reducing CPU latency for random reads.
