PrestoDb: A open source distributed SQL query engine


Presto DB Power full Query Engine

Presto DB is an open source distributed query engine to run interactive SQL(analytics query) on Big-Data which can be gigabytes to terabytes or petabytes. Presto was designed for interactive analytics and approaches the speed of commercial data warehouses while scaling to the size of organizations like Facebook.

Presto allows to querying data from Hadoop HDFS, Hive, Cassandra, relational databases or even proprietary data stores. A single presto query can combine data from multiple sources.

The main goal of Presto to deliver analytics query result in sub-seconds to minutes on non-expensive hardware like hadoop cluster. It's fully free.

Facebook uses Presto for interactive query against several internal data stores, including their 300 PB data warehouse. I personally tried presto DB on 3 node cluster with the data size of 1 TB to 3 TB data which resides on Hadoop HDFS and got the awesome performance in sub-seconds(calculations) and in microsecond to list sample data. As per my hands on I found Presto DB is read fast.

I had a challenge to make Apache hive or Apache spark comparable with Oracle query execution time, I tried many things but didn't get success. Finally came to Presto db & Kyline and found the Presto DB installation and managements are so simple as well as Presto query engine executes query in second or in micro seconds....


Its very easy to run 1000's of query on Presto DB over huge data with multiple session.

It supports multiple connectors to connect applications to Presto DB like:


  1. PHP connector   : To connect with PHP UI
  2. JDBC connector : To connect with JDBC application
  3. Rest API             : to connect with BI tools & restful services.

Setup Nginx as a Reverse Proxy for Thingsboard running on different port/server

In this blog, we will Setup Nginx as a Reverse Proxy for Thingsboard IOT dashboard running on different port Requirement: Ubuntu Server Thingsboard installed on Ubuntu server Nginx installed on Ubuntu server For installing please refer thingsboard documentation page windows:  https://thingsboard.io/docs/user-guide/install/windows/ Linux:  https://thingsboard.io/docs/user-guide/install/linux/ Let us know in comment if you face any issue in installation we will help you. NGINX installation: sudo apt-get install nginx sudo service nginx status sudo service nginx start Open your browser and you will see the default NGinx home page, nginx also runs on default port 80 In some case if you don't see default page up then check: If using cloud machine then need to open "http port 80" on 0.0.0.0/0 or a specific ip If still don't see UI then restart server, sometime it comes after restart.

How to auto re-launch a YARN Application Master on a failure.

1)Use Case: The fundamental idea of Hadoop2 (Map-Reduce + Yarn) is to split up the two major functionalities of the JobTracker, resource management and job scheduling/monitoring, into separate daemons. The idea is to have a global ResourceManager ( RM ) and per-application ApplicationMaster ( AM ). An application is either a single job in the classical sense of Map-Reduce jobs or a DAG of jobs. The ResourceManager and per-node slave, the NodeManager ( NM ), form the data-computation framework. The ResourceManager is the ultimate authority that arbitrates resources among all the applications in the system. The per-application ApplicationMaster is, in effect, a framework specific library and is tasked with negotiating resources from the ResourceManager and working with the NodeManager(s) to execute and monitor the tasks. The ResourceManager has two main components: 1. Scheduler: is responsible for allocating resources to the various running applications. 2. Appl

Read JSON File in Cassandra

Image
INSERT/Load Json data File in Cassandra (3.0+) table Requirement: Create Cassandra table where we can load json data into it. Here some of the column name is separated by space(like 'a b'). Load JSON file into the table. Challenge:  Cassandra support only 'CSV file' load in Table(As per my understanding and searched till now) by using 'COPY' command but not 'JSON' file. Resolution: As per the Cassandra document page, Cassandra supports CSV record level insert and file level insert both operation but for JSON it only support Record level insert by following command: cqlsh> INSERT INTO keyspace1.table1 JSON '{   "id" : "12",    "DB" : "Cassandra",    "ops" : "Insert",   "Project" : "Hadoop" }'; So If we want to insert whole file in the table then we need to loop for each object in JSON file and need to call insert query every tim
