Improving Presto Performance With Alluxio At Tiktok Ppt Alluxio, inc. this document discusses improving the performance of presto queries on hive data stored in hdfs by leveraging alluxio caching. it describes how tiktok integrated presto with alluxio to cache the most frequently accessed data partitions, reducing the median query latency by 41.2% and average latency by over 20% for cache hits. Improving presto performance with alluxio at tiktok. nowadays it is not straightforward to integrate alluxio with popular query engines like presto on existing hive data. solutions proposed by the community like alluxio catalog service or transparent uri brings unnecessary pressure on alluxio masters when querying files should not be cached.

Usage #the past window to define the working set alluxio.user.client.cache.shadow.window=24h #the total memory overhead for bloom filters used for tracking alluxio.user.client.cache.shadow.memory.overhead=125mb #the number of bloom filters used for tracking. each tracks a segment of window alluxio.user.client.cache.shadow.bloomfilter.num=4 15. This is because the alluxio client inside presto is unable to fetch data from alluxio workers before the predefined timeout value. in this case, one can increase alluxio.user work ty.timeout to a larger value (e.g., 10min). conclusion. through this article, we summarized the performance tuning tips to run the stack of presto and alluxio. It also discusses how presto and alluxio are used together to improve query performance through caching and eliminating network traffic. finally, it outlines ongoing explorations around improving presto and alluxio, such as load balancing, resource isolation, supporting larger clusters, and porting hdfs authentication to alluxio. read less.
