+However, with the exploration of cloud-native architectures, traditional shuffle solutions have revealed various issues. </p><p>In a cloud-native architecture, with use of techniques such as the separation of storage and compute, mixed deployment.The computational nodes have relatively low disk volume, poor IO performance, and an imbalance between CPU and IO resources.
+Additionally, computational nodes could be preempted by high-priority jobs due to mixed deployments.</p><p>In traditional Shuffle implementations, shuffle nodes tightly coupled with computational nodes. However, due to the different resource requirements for disk, memory and CPU between computational nodes and shuffle nodes, it is challenging to independently scale them based on their resource needs.
+By separating the computational nodes from shuffle nodes, the computational node's state becomes more lightweight after offloading the Shuffle state to shuffle nodes, reducing the job recomputation when computational nodes are preempted. </p><p>Decoupling computational and Shuffle nodes also reduces the demand for disk specifications on computational nodes, enabling an increase in the number of accessible computational nodes.</p><p>In cloud-native architectures, large Shuffle jobs c [...]
+Each system has made its own trade-offs based on different scenarios. Uniffle aims to create a fast, accurate, stable and cost-efficient cloud-native Remote Shuffle Service, considering performance, correctness, stability, and cost as its core aspects.</p><h2 class="anchor anchorWithStickyNavbar_LWe7" id="architecture">Architecture<a href="#architecture" class="hash-link" aria-label="Direct link to Architecture" title="Direct link to Architecture"></a></h2><p><img loading="lazy" alt="Ar [...]
+The essence of random IO is the existence of numerous small data block operations. In order to avoid these operations, Uniffle first aggregates multiple MapTasks' identical partitions in the memory of the Shuffle Server to generate larger partition data. When the Shuffle data in memory reaches the partition threshold or the overall threshold, it is written into local or remote storage.
+<img loading="lazy" alt="io_sort" src="/assets/images/io_sort-4e4445257d6dfd93fcbd173db1ad15ea.png" width="692" height="384" class="img_ev3q">
+When the overall threshold of memory reached, Uniffle sorted the partition data in memory based on their size. Uniffle write the larger partitions to the storage media first. Additionally, when the data in memory reach to a certain size, the writing of Shuffle data to the storage media is stopped, let some data stay in the memory to further reduce random IO on the disk.</p><h3 class="anchor anchorWithStickyNavbar_LWe7" id="3-storage-media-selection-strategy">3) Storage media selection st [...]
+For writing Shuffle data to local or remote storage, Uniffle has observed through testing that larger data block sizes result in better write performance for remote storage. When the data block size exceeds 64MB, the write performance to remote storage can reach 32MB/s. It's enough writing speed if we use multiple threads to write, comparing to the 100MB/s writing speed of HDD.Therefore, when writing data to storage media, Uniffle selects to write larger data blocks to remote storag [...]
+For computational engines like Spark AQE (Adaptive Query Execution), there are scenarios where a single task needs to read only a portion of a partition's data, as well as scenarios where multiple partitions need to be read. In the case of reading a portion of a partition's data, if the data is randomly distributed, it can result in a significant amount of read amplification. Performing data sorting and rewriting after the data is written can lead to considerable performance lo [...]

+In scenarios where multiple partitions need to be read, an optimization technique in Uniffle involves allocating the task of reading multiple partitions to a single ShuffleServer. This allows for the aggregation of Rpc (Remote Procedure Call) requests, which means that multiple Rpc requests can be sent to a single Shuffle Server. This approach helps to minimize network overhead and improve overall performance. For more detailed information, please refer to <!-- -->[4]<!-- -->.</p><h3 cla [...]

+Spark reports information about all completed tasks to the driver. In the first step of the reducer, the reducer retrieves a list of task unique identifiers from the driver. Blocks are the data sent from mappers to the shuffle server, and each block has a unique identifier. The data of a block is stored in memory, on local disk, or in HDFS. To ensure data integrity, Uniffle incorporates metadata verification. Uniffle designs index files for data files stored on local disks and in HDFS. T [...]
+To address data corruption issues, Uniffle performs CRC (Cyclic Redundancy Check) verification on data blocks. When reading data, Uniffle recalculates the CRC and compares it with the CRC stored in the file to determine if the data is corrupted. This helps prevent reading incorrect data.</p><h2 class="anchor anchorWithStickyNavbar_LWe7" id="stability">Stability<a href="#stability" class="hash-link" aria-label="Direct link to Stability" title="Direct link to Stability"></a></h2><h3 class [...]
+HDFS online clusters may experience some fluctuations in stability, which can result in failures to write data to HDFS during certain time periods. In order to minimize the impact caused by HDFS fluctuations, Uniff has designed a Fallback mechanism. When writing to HDFS fails, the data will be stored locally instead, reducing the impact on the job.</p><h3 class="anchor anchorWithStickyNavbar_LWe7" id="2-flow-control">2) Flow Control<a href="#2-flow-control" class="hash-link" aria-label=" [...]
