# File Aggregation Service
This service provides a fast/easy CSV aggregation of csv data. The current service REST API accepts a csv, a column to group on, and a column to aggregate and returns the result as plain text.
The service implementation is done using Apache Tuscany, which in the scope of this REST Service, provides a thin wrapper to a JAX-RS framework and enable service composition.
## Sample Input Data
```
first_name,last_name,count
piers,smith,10
kristen,smith,17
john,lee,3
sam,eagle,15
john,eagle,19
```
## Sample aggregated output
```
smith,27
lee,3
eagle,34
```
## Building the service
```
mvn clean install
```
## Starting the service
```
mvn exec:java
```
## Service invocation example
* Process input.csv and group on column 'last_name' and aggregate column 'count'
```
curl -X POST -H "Content-Type: multipart/form-data" -F "body=@input.csv" "http://localhost:8080/services/aggregator/csv?keyColumn=last_name&valueColumn=count"
```
* Process generated_input.csv and group on column 'last_name' and aggregate column 'count'
```
curl -X POST -H "Content-Type: multipart/form-data" -F "body=@generated_input.csv" "http://localhost:8080/services/aggregator/csv?keyColumn=last_name&valueColumn=count"
```
* Process generated_input.csv and group on column 'last_name' and aggregate column 'count'
```
curl -X POST -H "Content-Type: multipart/form-data" -F "body=@generated_input.csv" "http://localhost:8080/services/aggregator/csv?keyColumn=first_name&valueColumn=count"
```
Note: Make sure you are in the same folder as the available csv files (e.g. src/test/resources)
