In DiDi Chuxing Company, which is China’s most popular ride-sharing company. we use HBase to serve when we have a bigdata problem. We run three clusters which serve different business needs. We backported the Region Grouping feature back to our internal HBase version so we could isolate the different use cases. We built the Didi HBase Service platform which is popular amongst engineers at our company. It includes a workflow and project management function as well as a user monitoring view. Internally we recommend users use Phoenix to simplify access.even more,we used row timestamp;multidimensional table schema to slove muti dimension query problems C++, Go, Python, and PHP clients get to HBase via thrift2 proxies and QueryServer. We run many important buisness applications out of our HBase cluster such as ETA/GPS/History Order/API metrics monitoring/ and Traffic in the Cloud. If you are interested in any aspects listed above, please come to our talk. We would like to share our experiences with you.

HBase: Where Online Meets Low Latency

HBaseCon

This document summarizes a presentation about optimizing for low latency in HBase. It discusses how to measure latency, the write and read paths in HBase, sources of latency like garbage collection and compactions, and techniques for reducing latency like streaming puts, block caching, and timeline consistency. The key points are that single puts can achieve millisecond latency while garbage collection and machine failures can cause pauses of 10s of milliseconds to seconds, and optimizing for the "magical 1%" of requests after the 99th percentile is important to improve average latency.

HBase Accelerated: In-Memory Flush and Compaction

DataWorks Summit/Hadoop Summit

HBase Accelerated introduces an in-memory flush and compaction pipeline for HBase to improve performance of real-time workloads. By keeping data in memory longer and avoiding frequent disk flushes and compactions, it reduces I/O and improves read and scan latencies. Evaluation on workloads with high update rates and small working sets showed the new approach significantly outperformed the default HBase implementation by serving most data from memory. Work is ongoing to further optimize the in-memory representation and memory usage.

Speed Up Your Queries with Hive LLAP Engine on Hadoop or in the Cloud

gluent.

Hive was the first popular SQL layer built on Hadoop and has long been known as a heavyweight SQL engine suitable mainly for long-running batch jobs. This has greatly changed since Hive was announced to the world over 8 years ago. Hortonworks and the open source community have evolved Apache Hive into a fast, dynamic SQL on Hadoop engine capable of running highly concurrent query workloads over large datasets with sub-second response time. The latest Hortonworks and Azure HDInsight platform versions fully support Hive with LLAP execution engine for production use. In this webinar, we will go through the architecture of Hive + LLAP engine and explain how it differs from previous Hive versions. We will then dive deeper and show how features like query vectorization and LLAP columnar caching bring further automatic performance improvements. In the end, we will show how Gluent brings these new performance benefits to traditional enterprise database platforms via transparent data virtualization, allowing even your largest databases to benefit from all this without changing any application code. Join this webinar to learn about significant improvements in modern Hive architecture and how Gluent and Hive LLAP on Hortonworks or Azure HDInsight platforms can accelerate cloud migrations and greatly improve hybrid query performance!

Hive spark-s3acommitter-hbase-nfs

Yifeng Jiang

- The document discusses running Hive/Spark on S3 object storage using S3A committers and running HBase on NFS file storage instead of HDFS. This separates compute and storage and avoids HDFS operations and complexity. S3A committers allow fast, atomic writes to S3 without renaming files. Benchmark results show the magic committer is faster than the file committer for S3 writes. HBase performance tests show FlashBlade NFS providing low latency for random reads/writes compared to Amazon EFS.

Real time fraud detection at 1+M scale on hadoop stack

DataWorks Summit/Hadoop Summit

Rocketfuel processes over 120 billion ad auctions per day and needs to detect fraud in real time to prevent losses. They developed Helios, which ingests event data from Kafka and HDFS into Storm in real time, joins the streams in HBase, then runs MapReduce jobs hourly to populate an OLAP cube for analyzing feature vectors and detecting fraud patterns. This architecture on Hadoop allows them to easily scale real-time processing and experiment with different configurations to quickly react to fraud.

HBase Low Latency

DataWorks Summit

This document discusses techniques for improving latency in HBase. It analyzes the write and read paths, identifying sources of latency such as networking, HDFS flushes, garbage collection, and machine failures. For writes, it finds that single puts can achieve millisecond latency while streaming puts can hide latency spikes. For reads, it notes cache hits are sub-millisecond while cache misses and seeks add latency. GC pauses of 25-100ms are common, and failures hurt locality and require cache rebuilding. The document outlines ongoing work to reduce GC, use off-heap memory, improve compactions and caching to further optimize for low latency.

B.为什么我们提供的毕业证成绩单具有使用价值？查询留服认证是国内鉴别留学生海外学历的唯一途径但认证只是个体行为不是所有留学生都操作所以没有办理认证的留学生的学历在国内也是查询不到的他们也仅仅只有一张文凭。所以这时候我们提供的和学校颁发的一模一样的毕业证成绩单就有了使用价值。
