### Purpose The motivation of this PR is to reduce TabletServer RPC and local disk pressure when fetching high-throughput logs. Based on observations from production workloads, when ingestion throughput reaches around 20 GB/s, log fetch traffic from the tiering service can reach about 30 GB/s. This puts significant additional pressure on TabletServers, especially on RPC handling and local disk reads. ### Brief change log To address this, this PR makes it possible for tiering reads to fetch log data directly from remote storage when the requested offsets are already covered by remote logs. ### Tests <!-- List UT and IT cases to verify this change --> ### API and Format <!-- Does this change affect API or storage format --> ### Documentation <!-- Does this change introduce a new feature --> -- This is an automated message from the Apache Git Service.
