Integrate your REST API with AWS Services using API Gateway Service Proxy



Watch my YouTube video for explanation 



Please look into the class notes here for your references:


api gateway service proxy, api gateway proxy, api gateway dynamo,  api gateway dynamodb, dynamodb api, 
aws api gateway dynamodb, dynamodb api gateway, aws cloud, aws service cloud, aws tutorial, aws training

1.  DynamoDB Table    employee

     employee (empid as partition key, deptid as sort key)

2.  API Gateway Endpoint

      
  
  *create API -
              Create Resource, 
  Create Method , 
  Configure Method for post operation to DynamoDB service,
  Test the Method using JSON payload required 
      Deploy the Method
  Get the URL 
  Use Postman to post the data payload (JSON payload) to API gateway
  Receive the Response
  
  
  
3.  IAM Role 
     - policy
- trust relationship
 
 
 
{
    "TableName": "employee",
    "Item": {
        "empid": {
            "S": "1"
        },
        "deptid": {
            "S": "HR1"
        }
}
}
mapping tempplate
{
    "TableName": "employee",
    "Item": {
    
    "empid": {
             "S": "$context.requestId"
        },
    "deptid": {
            "S": "$input.path('$.deptid')"
        },
    "site": {
            "S": "$input.path('$.site')"
        }
}
}
Sample Input
{
"deptid":"admin1",
"site":"Bangaluru"
}

Abinitio Interview Question # 1 - Write Multiple Files in Abinitio

Image
 Question :  I get records of various region in huge volume ,  we want to write the records in region specific files.   How to achieve that? View the explanation in the below video: Answer: -WMF WMF: filename::get_filename(in)= begin let string("") l_filename=string_substring(in.data.region); filename::string_concat($AI_SERIAL,"/",l_filename.dat); end; out::reformat(in)= begin out::in.data; end; OUTPUT DML-: DML record string(int) filename; string(integer(4)) file_contents; end; RMF: filename::get_filename(in)= begin filename::string_concat($AI_SERIAL,"/",in.filename); end; out::reformat(read,filename,in)= begin out.file_contents::read; out.filename::filename; end; Please view my youtube channel  DataPundit

  Metaprogramming in Abinitio 1. How to create output DML dynamically based in INPUT DML 2. How to create intermediate transform( XFR) dynamically based on INPUT DML      Please See my you tube video for explanation : PART 1 PART 2 For Example, let us say, we have an Input DML as below-: cat input.dml record string(",") name; decimal(",") age; decimal(",") salary; string(",") aadharid; date("yyyy-mm-dd")(",") joiningdate; string(",") mobileno=NULL; string(",") dlno=NULL; string(",") passportnumber=NULL; end; (1.1) prepare a new DML based on input DML i.e. add fields, remove fields, modify type Graph based parameters: ===================================================================== input_dml=$DIR/input.dml  [interpretation = constant] input_dml_info =$[read_type(input_dml)]   [interpretation = pdl] /* Define functions in AB_DML_DEFS */ AB_DML_DEFS= $[ out:: dynamic_dml_gen(input_dml_info)= beg...

Next In Sequence in ABinitio | How next_in_sequence() works in MFS

Image
https://youtu.be/JdDDpjZcv-4 next_in_sequence() working in Abinitio: Definition -      within a single process(component) , this gives successive number.   next_in_sequence()>1 i.e. all records whose occurance is 2 and more in the file.      for example dataset below:    employeeName ram shyam ravi hanuman shekhar seeta geeta shayama vidushi vishakha If we process by condition next_in_sequence()>1 then the output will be [first record will be removed] shyam ravi hanuman shekhar seeta geeta shayama vidushi vishakha 2. next_in_sequence() with reformat  - rely -  FieldA 1a 2a 3a 4a 5a 6a 7a Example 1 (serial processing)--> Reformat   count=2      select:   next_in_sequence()<900      Transofom1:   out:reformat(in)=   begin   out.*::in.*;   out.Seq-No::next_in_sequence();   end;      Transform2:   out:reformat(in)=   begin   out.*:...
