I have a situation where we need to index a contents of a PDF file in Elastic Search. This can be easily achieved using a FS river plugin but the pdf file is stored as a BLOB object in a database, this means a JDBC river plugin is also in picture now. Please let me know your thoughts on this. I will have a look on Attachments Mapper plugin to see if it can replace a FS river plugin and read a BLOB directly.

You can combine JDBC plugin and attachment mapper if your database can convert the blob to base64 string.

With MySQL blob, you do not need base64 conversion by DB, because JDBC driver works correct. The base64 conversion is performed by JDBC river when indexing. Maybe other DB work like MySQL too.
