Import tool: Apache Kafka 1.0 (
Import interface: [NoSQL Database] Multi-Model, Data Store (NoSQL / Hierarchical, Physical Data Model) via Java API on Kafka File from Apache Kafka
Import bridge: 'ApacheKafka' 10.1.0

This bridge requires internet access to (and exceptionally a few other tool sites)
in order to download the necessary third party software libraries into $HOME/data/download/MIMB/
(such directory can be copied from another MIMB server with internet access).
By running this bridge, you hereby acknowledge responsibility for the license terms and any potential security vulnerabilities from these downloaded third party software libraries.


Loads metadata from all or specified Kafka topics. Each topic is assumed to have messages of the same type. The bridge samples multiple messages to figure our their common structure.
This bridge supports the following file formats:
- Flat File (CSV)
- Open Office Excel (XSLX)
- COBOL Copybook
- JSON (JavaScript Object Notation)
- Apache Avro
- Apache Parquet
- Apache ORC

as well as the compressed versions of the above formats:
- ZIP (as a compression format, not as archive format)
- LZ4
- Snappy (as standard Snappy format, not as Hadoop native Snappy format)

Known issue: When you run both Kafka cluster (server) version 1.1.x and the bridge (client) on Windows systems the import could fail with a timeout error. The Kafka version 2.0.x resolved the issue.
Please refer to the individual parameter's tool tips for more detailed examples.

Bridge Parameters

Parameter Name Description Type Values Default Scope
Bootstrap servers List of host:port pairs to use for establishing the initial connection to the Kafka cluster, and finding available servers and topics.
For example, 'host1:port1, host2:port2'.
The list does not need to include all available servers but should have at least one.
You may want to include more than one server in case any of them are down.
STRING   localhost:9092 Mandatory
Driver version The Kafka bootstrap server driver version in the N.N.N format, like 1.1.0
The version is used to load the necessary version-specific libraries.
STRING   1.1.0 Mandatory
Use SSL protocol to connect Set this parameter to True when the Kafka consumer uses TLS/SSL to encrypt Kafka's network traffic.

Kafka uses SSL to encrypt connections between the server and clients

Truststore file The location of the trust store file.
If it is empty the bridge would try to locate it in 'java.home'\lib\security\{'jssecacerts'|'cacerts'}
FILE *.*    
Password of the truststore Password of the truststore. PASSWORD      
Topics List of topic names, like 'topic1, topic2'.
An empty list means that all available topics.
You can specify topic names as a wieldcard pattern: 'topic?' , '*topic*' or 'topic_?,*topic*'.
Number of sample messages The maximum number of messages to sample from topics. These messages are used to identify topic format details, like field names and data types.
When empty, the number of sample messages is assumed to be 1000.
