Whether this is doable or achievable :

- To Fetch CLOB data from Oracle using LogStash JDBC Input Plugin
- We are storing log Files in Oracle Table where Column is of type CLOB
- How can i retrieve the CLOB data and how can i filter this data.
- Each row contain 1 Log File (in CLOB data type column)
- Note: The character in each log file is more than 40,000.  
It will be really helpful if someone can provide some pointers Or examples for the same. I am new to ELK hence required some guidance.
