Please share the HW and SW specs and the results. column 0-7 are primary keys and we can't change that because of the uniqueness. 03:06 PM. for the dim tables, we hash partition it into 2 partitions by their primary (no partition for parquet table). Delta Lake: Reliable Data Lakes at Scale.An open-source storage layer that brings ACID transactions to Apache Spark™ and big data workloads; Apache Parquet: *A free and open-source column-oriented data storage format *.

Please … ‎06-26-2017 KUDU VS PARQUET ON HDFS TPC-H: Business-oriented queries/updates Latency in ms: lower is better 34. Tight integration with Apache Impala, making it a good, mutable alternative to using HDFS with Apache Parquet. Below is my Schema for our table. - edited ‎05-19-2018 In total parquet was about 170GB data. Thanks all for your reply, here is some detail about the testing. Apache Kudu merges the upsides of HBase and Parquet. 02:34 AM Can you also share how you partitioned your Kudu table? Delta Lake vs Apache Parquet: What are the differences? 03:03 PM. ‎06-26-2017 For further reading about Presto— this is a PrestoDB full review I made. and the fact table is big, here is the 'data siez-->record num' of fact table: 3, Can you also share how you partitioned your Kudu table? i notice some difference but don't know why, could anybody give me some tips? Apache Hadoop and it's distributed file system are probably the most representative to tools in the Big Data Area. Impala can also query Amazon S3, Kudu, HBase and that’s basically it. impalad and kudu are installed on each node, with 16G MEM for kudu, and 96G MEM for impalad. Apache Spark SQL also did not fit well into our domain because of being structural in nature, while bulk of our data was Nosql in nature. Created here is the 'data siez-->record num' of fact table: https://github.com/cloudera/impala-tpcds-kit), we. 2, What is the total size of your data set? Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. Make sure you run COMPUTE STATS after loading the data so that Impala knows how to join the Kudu tables. Re: Kudu Size on Disk Compared to Parquet. Created I've created a new thread to discuss those two Kudu Metrics. The ability to append data to a parquet like data structure is really exciting though as it could eliminate the … related Apache Kudu posts. By … We can see that the Kudu stored tables perform almost as well as the HDFS Parquet stored tables, with the exception of some queries(Q4, Q13, Q18) where they take a much longer time as compared to the latter. So in this case it is fair to compare Impala+Kudu to Impala+HDFS+Parquet. With the 18 queries, each query were run with 3 times, (3 times on impala+kudu, 3 times on impala+parquet)and then we caculate the average time. JSON. ‎06-27-2017 While compare to the average query time of each query,we found that  kudu is slower than parquet. While compare to the average query time of each query,we found that  kudu is slower than parquet. Regardless, if you don't need to be able to do online inserts and updates, then Kudu won't buy you much over the raw scan speed of an immutable on-disk format like Impala + Parquet on HDFS. Apache Kudu is a new, open source storage engine for the Hadoop ecosystem that enables extremely high-speed analytics without imposing data-visibility latencies. ‎06-27-2017 Our issue is that kudu uses about factor 2 more disk space than parquet (without any replication). It's not quite right to characterize Kudu as a file system, however. It aims to offer high reliability and low latency by … Time Series as Fast Analytics on Fast Data Since the open-source introduction of Apache Kudu in 2015, it has billed itself as storage for fast analytics on fast data. for those tables create in kudu, their replication factor is 3. ‎06-26-2017 I am quite interested. Any ideas why kudu uses two times more space on disk than parquet? Apache Parquet - A free and open-source column-oriented data storage format . based on preference data from user reviews. In total parquet was about 170GB data. Storage systems (e.g., Parquet, Kudu, Cassandra and HBase) Arrow consists of a number of connected technologies designed to be integrated into storage and execution engines. Parquet is a read-only storage format while Kudu supports row-level updates so they make different trade-offs. ‎06-27-2017 It has been designed for both batch and stream processing, and can be used for pipeline development, data management, and query serving. Kudu is still a new project and it is not really designed to compete with InfluxDB but rather give a highly scalable and highly performant storage layer for a service like InfluxDB. E.g. 03:02 PM - edited This general mission encompasses many different workloads, but one of the fastest-growing use cases is that of time-series analytics. They have democratised distributed workloads on large datasets for hundreds of companies already, just in Paris. hi everybody, i am testing impala&kudu and impala&parquet to get the benchmark by tpcds. Kudu has high throughput scans and is fast for analytics. It is a columnar storage format available to any project in the Hadoop ecosystem, regardless of the choice of data processing framework, data model or programming language; *Kylo:** Open-source data lake management software platform. I think we have headroom to significantly improve the performance of both table formats in Impala over time. ‎06-26-2017 01:19 AM, Created I think Todd answered your question in the other thread pretty well. We have measured the size of the data folder on the disk with "du". ‎05-20-2018 parquet files are stored on another hadoop cluster with about 80+ nodes(running hdfs+yarn). in Impala 2.9/CDH5.12 IMPALA-5347 and IMPALA-5304 improve pure Parquet scan performance by 50%+ on some workloads, and I think there are probably similar opportunities for Kudu. we have done some tests and compared kudu with parquet. I've checked some kudu metrics and I found out that at least the metric "kudu_on_disk_data_size" shows more or less the same size as the parquet files. With Kudu, Cloudera has addressed the long-standing gap between HDFS and HBase: the need for fast analytics on fast data. The key components of Arrow include: Defined data type sets including both SQL and JSON types, such as int, BigInt, decimal, varchar, map, struct and array. Using Spark and Kudu… Stacks 1.1K. In other words, Kudu provides storage for tables, not files. However the "kudu_on_disk_size" metrics correlates with the size on the disk. How much RAM did you give to Kudu? side-by-side comparison of Apache Kudu vs. Apache Parquet. Impala heavily relies on parallelism for throughput so if you have 60 partitions for Kudu and 1800 partitions for Parquet then due to Impala's current single-thread-per-partition limitation you have built in a huge disadvantage for Kudu in this comparison. Created KUDU VS HBASE Yahoo! thanks in advance. Created Databricks says Delta is 10 -100 times faster than Apache Spark on Parquet. Find answers, ask questions, and share your expertise. 09:05 PM, 1, Make sure you run COMPUTE STATS: yes, we do this after loading data. I am surprised at the difference in your numbers and I think they should be closer if tuned correctly. Kudu shares the common technical properties of Hadoop ecosystem applications: it runs on commodity hardware, is horizontally scalable, and supports highly available operation. Created It supports multiple query types, allowing you to perform the following operations: Lookup for a certain value through its key. ‎06-27-2017 @mbigelow, You've brought up a good point that HDFS is going to be strong for some workloads, while Kudu will be better for others. which dim tables are small(record num from 1k to 4million+ according to the datasize generated. open sourced and fully supported by Cloudera with an enterprise subscription ‎05-20-2018 It is as fast as HBase at ingesting data and almost as quick as Parquet when it comes to analytics queries. The default is 1G which starves it. 8. Kudu’s write-ahead logs (WALs) can be stored on separate locations from the data files, which means that WALs can be stored on SSDs to enable lower-latency writes on systems with both SSDs and magnetic disks. http://blog.cloudera.com/blog/2017/02/performance-comparing-of-different-file-formats-and-storage-en... https://github.com/cloudera/impala-tpcds-kit, https://www.cloudera.com/documentation/kudu/latest/topics/kudu_known_issues.html#concept_cws_n4n_5z.

Like HBase, Kudu has fast, random reads and writes for point lookups and updates, with the goal of one millisecond read/write latencies on SSD. which dim tables are small(record num from 1k to 4million+ according to the datasize generated). Kudu stores additional data structures that Parquet doesn't have to support its online indexed performance, including row indexes and bloom filters, that require additional space on top of what Parquet requires. ‎06-26-2017 However, it would be useful to understand how Hudi fits into the current big data ecosystem, contrasting it with a few related systems and bring out the different tradeoffs these systems have accepted in their design.
