time time series column oriented data store license apache license 2 0 website druid apache org druid is a column oriented open source distributed data store written in java druid is designed to quickly ingest massive quantities of event data and provide low latency queries on top of the data 3 the name druid comes from the shapeshifting druid class in many role playing games to reflect that the architecture of the system can shift to solve different types of data problems druid is commonly used in business intelligence olap applications to analyze high volumes of real time and historical data 4 druid is used in production by technology companies such as alibaba 4 airbnb 4 cisco 5 4 ebay 6 lyft 7 netflix 8 paypal 4 pinterest 9 reddit 10 twitter 11 walmart 12 wikimedia foundation 13 and

tschetter fangjin yang gian merlino and vadim ogievetsky 15 to power the analytics product of metamarkets the project was open sourced under the gpl license in october 2012 16 17 and moved to an apache license in february 2015 18 19 architecture edit fully deployed druid runs as a cluster of specialized processes called nodes in druid to support a fault tolerant architecture 20 where data is stored redundantly and there is no single point of failure 21 the cluster includes external dependencies for coordination apache zookeeper metadata storage e g mysql postgresql or derby and a deep storage facility e g hdfs or amazon s3 for permanent data backup query management edit client queries first hit broker nodes which forward them to the appropriate data nodes either historical or real time since druid segments may be partitioned an incoming query can require data from multiple segments and partitions or shards stored on different nodes in the cluster brokers are able to learn which nodes have the required data and also merge partial results before returning the aggregated result cluster management edit operations relating to data management in historical nodes are overseen by coordinator nodes apache zookeeper is used to register all nodes manage certain aspects of internode communications and provide for leader elections features edit low latency streaming data ingestion arbitrary slice and dice data exploration sub second analytic queries approximate and exact computations performance edit researchers have compared the performance of hive presto and druid using a denormalized star schema benchmark based on the tpc h standard druid was tested using both a druid best configuration using tables with hashed partitions and a druid suboptimal configuration which does not use hashed partitions 22 tests were conducted by running the 13 tpc h queries using tpc h scale factor 30 a 30gb database scale factor 100 a 100gb database and scale factor 300 a 300gb
