Prometheus.spec.thanos.blockSize

BlockDuration controls the size of TSDB blocks produced by Prometheus. The default value is 2h to match the upstream Prometheus defaults. WARNING: Changing the block duration can impact the performance and efficiency of the entire Prometheus/Thanos stack due to how it interacts with memory and Thanos compactors. It is recommended to keep this value set to a multiple of 120 times your longest scrape or rule interval. For example, 30s * 120 = 1h.
