ABytes := TFile.ReadAllBytes('d:\red.bmp')
FKafkaProducer.Produce(edtTopic.Text, @abytes, length(ABytes))

//bytes: 66, 77, 186, 1, ...

in TfrmConsume.Start

MsgRec.Data := TKafkaUtils.PointerToBytes(Msg.payload, Msg.len)

//bytes 152, 231, 229, 8, ...

data length matches!

what am I doing wrong?

Hi Team ,

Is provided Delphi code/packages/ components will work with Confluent kafka ?

When specifying a topic name to subscribe to (in TKafkaFactory.NewConsumer), regex wildcards do not work (^* or anything else).

rd_kafka_subscribe description says that

 * Wildcard (regex) topics are supported:
 * any topic name in the \p topics list that is prefixed with \c \"^\" will
 * be regex-matched to the full list of topics in the cluster and matching
 * topics will be added to the subscription list.

However, specifying any wildcards for it and calling it does not seem to work either.

Maybe there is some special regex string handling required?

Hi

Using your library, I have found an issue when I try to connect to a kafka server hosted in Azure.
A typical configuration string for kafka hosted in Azure accessible by WindowsAzure.ServiceBus is
'sasl.password=Endpoint=sb://[namespace].servicebus.windows.net/;SharedAccessKeyName=RootManageSharedAccessKey;SharedAccessKey=[SAS key]'

The TKafkaUtils.StringsToConfigArrays procedure in the Kafka.Helper unit fails when spliting string values with more than one '=' character.

An alternative implementation of this procedure could be

class procedure TKafkaUtils.StringsToConfigArrays(const Values: TStrings; out NameArr, ValueArr: TArray);
var i, p: Integer;
begin
for i := 0 to pred(Values.Count) do
begin
p := Values[i].IndexOf('=');
if p>=0 then begin
NameArr := NameArr + [Values[i].Substring(0,p)];
ValueArr := ValueArr + [Values[i].Substring(p+1)];
end;
end;
end;

Best Regards

how to set/get this kafka_* header?

Good morning, I can't run it in 64 bits, do you have the dll to run the example project in 64 Bits?

I have issues with downloading DLLs from non-official sources.
