Question:
Can't use attr_persistence column on mysql sink

Description:
I'm trying to use the column type with OrionMySQLSink. My agent has this code:

cygnusagent.sinks.mysql-sink.type = com.telefonica.iot.cygnus.sinks.OrionMySQLSink
cygnusagent.sinks.mysql-sink.channel = mysql-channel
cygnusagent.sinks.mysql-sink.enable_grouping = false
cygnusagent.sinks.mysql-sink.mysql_host = localhost
cygnusagent.sinks.mysql-sink.mysql_port = 3306
cygnusagent.sinks.mysql-sink.mysql_username = ********
cygnusagent.sinks.mysql-sink.mysql_password = *********
cygnusagent.sinks.mysql-sink.table_type = table-by-destination
cygnusagent.sinks.mysql-sink.attr_persistence = column
cygnusagent.sinks.mysql-sink.batch_size = 1
cygnusagent.sinks.mysql-sink.batch_timeout = 10

I'm having this error when I use the sink:

2015-12-14 08:43:58,118 (SinkRunner-PollingRunner-DefaultSinkProcessor) [ERROR - com.telefonica.iot.cygnus.sinks.OrionSink.process(OrionSink.java:187)] Persistence error (Unknown database 'fiw-serv')

I don't have any problem with row mode, only with column mode.
