Lambda Architecture vs. Lambda Expression vs. AWS Lambda

Lambda Architecture is a data processing architecture involving huge amount of data  with goals of providing real time views without sacrificing accuracy. Typically when large amount of data is involved, the data processing takes time so you can not have real time views/reports. If you want real time view then you can take into account all the data so views are inaccurate. Lambda architecture tries to address it by combining real time processing on limited amount of data with batch processing on the entire data set.

Lambda expression in Java 8 is a simplified expression of  defining an anonymous class having single method whose type is inferred. The type of Lambda Expression(  (args)->{body}  ) is one of the FunctionalInterface.

AWS Lambda is a AWS hosted service which allows you to execute code on certain events without worrying about infrastructure where it runs( serverless architecture).

Joins - Not always very obvious ( Following example uses Hive ). create table x_temp ( name string, p_date int  ) insert into x_temp(name,p_date) values ('x1',20181025),('x2', 20181026), ('x3',20181027) create table y_temp ( name string, s_date int  ) insert into y_temp(name,s_date) values ('x1',20181025),('x2', 20181026), ('x3',20181027) create table z_temp ( name string, p_date int, s_date int ) insert into z_temp(name,p_date,s_date) values ('z1','20181025','20181025') select x.*, y.* from x_temp x, y_temp y, z_temp z  where x.p_date != z.p_date and  y.s_date != z.s_date) generates 4 records... x.name,x.p_date,y.name,y.s_date x2, 20181026, x2, 20181026 x3, 20181027, x2, 20181026 x2, 20181026, x3, 20181027 x3, 20181027, x3, 20181027 select x.*, y.* from x_temp x, y_temp y, z_temp z  where x.p_date != z.p_date or  y.s_date != z.s_date) generates 8 records x.name,x.p_date,y....

DBeaver

Recently I used this tool for connecting to Hive via Knox gateway.  Good thing about this tool is that it automatically downloads the driver and configures it. That  is a pain in tools like Squirrel.  It also makes a JDBC connection to Hive.  Below is how the HOST and JDBC URL settings look like : HOST : <KNOX_HOST>:8443/;ssl=true;transportMode=http;httpPath=gateway/<topology>/hive JDBC URL :  jdbc:hive2://<KNOX_HOST>:8443/;ssl=true;transportMode=http;httpPath=gateway/<topology>/hive What I noticed on my setup was that if you keep the default port which 10000 and you set it to 8443 , it does not work. So you have to keep it blank.  That may be specific to my setup. Also you might notice that ssl=true but there are  no  sslTrustStore= < Path to the “.jks” file in the NiFi node > ;trustStorePassword= < TrustStore Password>  parameters. The reason is if you import the gateway cert  into the trus...
