The MODULE_INFO is now the main object which is used by modules to convey
information to the MaxScale core. The MXS_MODULE name is more apt as it
now contains the actual module definition.
The old MODULES structure was moved into load_utils.c as an internal
implementation and was renamed so that it is not confused with the new
MODULE structure.
The modules are now declared with a common macro. This allows future
additions to the module loading process while also making the loaded
symbol name a constant.
This allows modules to only expose one entry point with a consistent
signature. In the future, this could be used to implement declarations of
module parameters.
Currently, when the avrorouter finishes reading a binlog file or when a
certain number of rows or transactions is reached, it will flush all
tables to disk. This is quite slow as events can easily be written faster
into the binlog than they can be processed by avrorouter.
A solution to this would be to only sync the tables (close the Avro block)
instead of flushing them to disk. This would allow more efficient
processing of the files while still retaining the safe shutdown that
flushing offers.
The DECIMAL value type is now properly handled in Avrorouter. It is
processed into an Avro double value when before it was ignored and
replaced with a zero integer.
