The code that handles the Avro files is now fully abstracted behind the
AvroConverter class that implements the RowEventHandler interface.
The code still has some avro specific behavior in a few places (parsing of
JSON files into TableCreate objects). This can be replaced, if needed, by
querying the master server for the CREATE TABLE statements.
The various file operation related binlog events are now processed on the
upper level. This makes the actual data event processing simpler and
easier to comprehend.
If the avrorouter is being build and the required libraries are not found,
the configuration process should fail. Adding the command to bypass this
into the error message should make it easier to disable this part if it is
not needed.
The parser checks whether the FIRST or AFTER keywords are used and, if
AFTER is used, extracts the relevant column name.
Added a test case that checks that the parsing works and detects the
correct column names.
According to customer reports collecting the statistics has a significant
impact on the performance. As we don't need that information we can just
as well turn off that.
Further, since maxscale-common now links to the sqlite3-library, no
module needs to do that explicitly.
