Printing all output as raw bytes allows MaxScale to control the formatting
process. This also removes the need to convert the bytes to Python strings
and the need to parse the JSON.
The order of the servers in the service definition could break the
master_accept_reads functionality.
When the first server defined in the service is a slave, it will always be
picked as the first candidate for reads. The master would only be
considered as a candidate for reads if no previous candidate was
available. For this reason, the master_accept_reads only worked when the
first server in the list was the master.
The Avro C API fails to write bytes of size zero. A workaround is to write
a single zero byte for each NULL field of type bytes.
Also added an option to configure the Avro block size in case very large
records are written.
The rotations of binlogs weren't detected as the file names weren't
compared.
Moved the indexing of the binlogs to the end of the binlog
processing. This way the files can be flushed multiple times before they
are indexed.
The old DATETIME format wasn't processed properly which caused a
corruption of following events.
A BLOB type value could be non-NULL but still have no data. In this case,
the value should be stored as a null Avro value.
The DECIMAL type was not correctly converted to positive integers. The
0x80 bit was set only for negative numbers when it needed to be XOR-ed for
all values.
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.
Backported to the 2.0 branch.
An error was logged when the end of file was reached. The error should
only be logged when a partial sync marker is read and the end of file has
not been reached.
In a configuration with multiple services, one with connection_timeout and
others without it, the connections to non-connection_timeout services
would get immediately closed due to integer overflow.
The backtick was copied to the field name and converted to an underscore
when the name was transformed into a valid Avro identifier. This caused
one extra character to appear in the field name in the Avro schema files.
As the cdc_kafka_producer script is an example, it should flush the
producer after every new record. This should make it easier to see that
events from MaxScale are sent to Kafka.
