Loki, a log storage solution built on the Cortex architecture, has implemented optimizations to significantly reduce its log storage requirements, achieving nearly three times less data storage than previous versions. Originally, Cortex introduced changes like label sorting and using Memcached to avoid duplicate chunk uploads, which were then applied to Loki. Loki, which utilizes log lines instead of metric samples, adapted these improvements with a focus on chunk size rather than a fixed time window due to its distinct data structure. By synchronizing chunk cutting based on both time and utilization thresholds, Loki reduced duplicate data storage from three copies to approximately 1.2 copies, enhancing storage efficiency and search speed. Despite this progress, some issues persist, such as synchronization challenges among ingesters and occasional desynchronization. The ongoing development aims to fine-tune the synchronization process to further enhance storage efficiency, particularly for busy series that would benefit most from deduplication.
