Hi Team,

I am trying to Load the data from Postgresql to Apache Druid(apache-druid-0.17.0) , but I am getting below error:

"SQL firehose error with org.apache.druid.segment.realtime.firehose.SqlFirehoseFactory cannot be cast to org.apache.druid.data.input.FiniteFirehoseFactory."

seems the issue is already resolve in the below Ticket request:

*SQL firehose error #9359
*Fix compatibility issues with SqlFirehose #9365

Could you please help me to get the new io-configuration for the postgresql.

Currently we are using below io-config for which we are getting above error:
"ioConfig": {
"type": "index",
"firehose": {
"type": "sql",
"database": {
"type": "postgresql",
"connectorConfig": {
"connectURI": "jdbc:postgresql://<Host_Name>:<PortNo.>/<DB_Name>",
"user": "<User_Name>",
"password": "<Pass_word>"
}
},
"sqls": [
"select * from Table;"
]
}
}

Hi @MoushmiDas ,the fix for this is merged to master and so unfortunately it is unavailable with the 0.17.0 release. You could however build druid from source with the master branch. Instructions here: https://druid.apache.org/docs/latest/development/build.html
