Re:Kylin and parquet question
Hi, I'm sorry, please ignore my last reply, there are some bad formats. We are preparing an article about improving performance for building/querying on kylin4, which will list some properties about performance and descript how to configure these properties to improve building/querying performance. We will publish this article on apache kylin wiki ASAP. Best regards, Zhichao Zhang
??????Kylin and parquet question
Hi, We are preparing an article about improving performance for building/querying on kylin4, which will list some properties about performance and descript how to configure these properties to improve building/querying performance. We will publish this article on apache kylin wiki ASAP. Best regards, Zhichao Zhang -- -- ??: "dev" https://cwiki.apache.org/confluence/display/KYLIN/KIP-1%3A+Parquet+storage the new storage engine will be parquet and the queries will go through apache spark jobs. I'm not so familiar with apache spark but I think that it's not easy to tune it to support a lot of concurrent queries. What would be the guideline for configuring kylin + parquet to support for example 100 concurrent queries per second? What kind of deployment (machine types) and configurations will work in that case? -- Greetings, Ivan Georgiev
Re: [Announce] Apache Kylin 4.0.0-alpha released
Congratulations! I've been waiting for this day for a long time. Truly thanks for the community's hard work. Regards! Aron Tao George Ni 于2020年9月13日周日 下午7:57写道： The Apache Kylin team is pleased to announce the immediate availability of the 4.0.0-alpha release. This is a major release after 3.1.0, with 35 new features and 22 bug fixes. All of the changes in this release can be found in: https://kylin.apache.org/docs/release_notes.html You can download the source release and binary packages from Apache Kylin's download page: https://kylin.apache.org/download/ Apache Kylin is an open-source Distributed Analytical Data Warehouse for Big Data; it was designed to provide OLAP (Online Analytical Processing) capability in the big data era. By renovating the multi-dimensional cube and precalculation technology on Hadoop and Spark, Kylin is able to achieve near-constant query speed regardless of the ever-growing data volume. Reducing query latency from minutes to sub-second, Kylin brings online analytics back to big data. Apache Kylin lets you query billions of rows at sub-second latency in 3 steps: 1. Identify a Star/Snowflake Schema on Hadoop. 2. Build Cube from the identified tables. 3. Query using ANSI-SQL and get results in sub-second, via ODBC, JDBC or RESTful API. Thanks to everyone who has contributed to this release. We welcome your help and feedback.
