Here are some of the steps you can follow to export data generated by Apache
Age for analysis with Apache Giraph.
Let's say you have a graph that represents a set of teachers and their
status. The teacher node has properties like "teacher_id", "name", "age", while
the status edges will have properties like: "status_id", and "status".
To export this graph data from Apache AGE for analysis with Apache Giraph,
you can follow these steps:
Export the data as a separate CSV file:
- Use the below query to retrieve the Teacher's data from the tables in
Apache Age and export it to a CSV file. For example, you will execute a query
like:
`COPY (SELECT teacher_id, name, age FROM teacher) TO '/path/to/teachers.csv'
CSV HEADER;`
Similarly, exporting the status data as a separate CSV file:
`COPY (SELECT status_id, status FROM status) TO '/path/to/status.csv' CSV
HEADER;`
- Now transport the above-exported data into an edge list.
- In Apache Giraph the data is typically represented as an edge list,
where each line represents an edge between 2 nodes. You need to transform the
exported data from apache age into this format.
- Create a new file graph.txt and write the transformed data in the edge
list format. each line in the file would represent a status edge between 2
teachers.
- The file will look something like this:
- `teacher1, teacher2
teacher1, teacher3
teacher2, teacher3`
- Now import the transformed data into the Apache Giraph. You can use
different tools of Giraph for analyzing the graph data.
