Customizing the River

Elastic Stack Elasticsearch
1

Hi ,

I am in need of customizing the elastic search river to suit our
requirements. Basically , I need to be able to take the data from the
database which is in an encrypted format and decrypt the data and index the
decrypted data. I need pointers on how to start , feasibility of such an
approach and which files to change , so that I can get started on it.

Thanking you in advance for any light that can be shed

Hi,

generally speaking it is feasible to move data over to elasticsearch
from a database. You can start with the JDBC river

If you can give an example of data, how it is encrypted and what
decrypting function you think of, I could suggest where to start, yes.

Best regards,

Jörg

Hi Prante ,

Thank you for your reply , The encryption is configurable by the user and
is done in Java ( Business Logic layer) , so I would need to intercept the
entity prior to indexing , apply the appropriate decryption algorithm and
then index it into elasticsearch. I am thinking if I can extend the class
which indexes the data and do this manipulation. Your thoughts on achieving
the same would be of immense help.

Thanks

Hi,

that's what I understand, look at
GitHub - jprante/elasticsearch-jdbc: JDBC importer for Elasticsearch - if you extend the
SimpleRiverSouce and the SimpleValueListener class you can easily add
decryption on specific database columns, I recommend adding a new
'decrypt' strategy in a new subpackage.

Best regards,
