Hello Devs, I'd like to contribute better groovy processor for nifi. We are going to use it in production.. Questions: - Do you think Is it interesting? - If yes, where i should start? From master or specific branch?
The main features: - it's absolutely compatible with existing Execute Script / Groovy - if property starts with `CTL.` - it's possible to connect to any controller service by this it's possible to connect several databases, jms, cache, ... in one processor and mix data - if connection pool connected to script then connection taken from pool and provided to script as groovy.sql.Sql http://docs.groovy-lang.org/latest/html/api/groovy/sql/Sql.html all sql connections are committed on script success and rolled back on exception - Script now is more groovy: def ff = session.get() if( !ff ) return ff.myAttr = 'The New Attr Value' def row = CTL.mydb.firstRow("select sysdate as DAT from dual") ff.write('UTF-8') { writer-> writer << groovy.json.JsonOutput.toJson(row) } REL_SUCCESS << ff - Exception policy: `rollback` or `transfer to failure` -- Regards, Dmitry
