Aug 1, 2025

Month: 2025-08 — Storj storj repo focused on throughput, configurability, and reliability of the upload pipeline. Delivered two feature enhancements that improve control and performance: - Satellite Node Selection Cohort Configuration: implemented a new configuration language to configure node selection cohorts, supporting criteria like minimum node counts, AND operations, and tag-based withholding to govern which nodes are eligible for uploads. Commits: 08684825a113a6467457db359aee4d0cd317fdff (satellite/nodeselection: support configuring cohorts). - Upload Burst-Enabled Bloom Rate Limiter: redesigned rate limiter from an LRU cache to a token-bucket-based bloom rate limiter, enabling bursts while preventing abuse; added tunable options for burst limit, hash count, and size exponent to tailor behavior. Commits: 1877d5d7c34ac6d9563b62310bbec74adcf91d3a (satellite/metainfo: add support for bursting to single path upload limiting). Overall, the period emphasized feature delivery and performance improvements in the upload pipeline; there were no explicit bug fixes reported in the provided data, but the changes contribute to stability, throughput, and security of uploads. All work is in repository storj/storj.
