Consume / Publish Kafka And Store to Files, HDFS, Hive 3.1, Kudu

 

 

Consume Kafka Flow 

 

 

 Merge Records And Store As AVRO or ORC

 

Consume Kafka, Update Records via Machine Learning Models In CDSW And Store to Kudu

 

 

Source:  Apache Kafka Topics

 

You enter a few parameters and start ingesting data with or without schemas.   Apache Flume had no Schema support.   Flume did not support transactions.

 

 

 

Sink:   Files

 

 

 

Storing to files in files systems, object stores, SFTP or elsewhere could not be easier.  Choose S3, Local File System, SFTP, HDFS or wherever.

 

Sink:   Apache Kudu / Apache Impala

 

 

Storing to Kudu/Impala (or Parquet for that manner could not be easier with Apache NiFi).

 

 

Sink:   HDFS for Apache ORC Files

 

When completes, the ConvertAvroToORC and PutHDFS build the Hive DDL for you!  You can build the tables automagically with Apache NiFi if you wish.

 

CREATE EXTERNAL TABLE IF NOT EXISTS iotsensors

(sensor_id BIGINT, sensor_ts BIGINT, is_healthy STRING, response STRING, sensor_0 BIGINT, sensor_1 BIGINT,

sensor_2 BIGINT, sensor_3 BIGINT, sensor_4 BIGINT, sensor_5 BIGINT, sensor_6 BIGINT, sensor_7 BIGINT, sensor_8 BIGINT,

sensor_9 BIGINT, sensor_10 BIGINT, sensor_11 BIGINT)

STORED AS ORC

LOCATION '/tmp/iotsensors'

 

 

 

 

 

Sink: Kafka

Publishing to Kafka is just as easy!  Push records with schema references or raw data.  AVRO or JSON, whatever makes sense for your enterprise.

 

Write to data easily with no coding and no changes or redeploys for schema or schema version changes.

 Pick a Topic and Stream Data While Converting Types

 

 

Clean UI and REST API to Manage, Monitor, Configure and Notify on Kafka

 

 

 

Other Reasons to Use Apache NiFi Over Apache Flume

DevOps with REST API, CLI, Python API

 

Schemas!   We not only work with semi-structured, structured and unstructured data.  We are schema and schema version aware for CSV, JSON, AVRO, XML, Grokked Text Files and more. https://community.cloudera.com/t5/Community-Articles/Big-Data-DevOps-Apache-NiFi-HWX-Schema-Registry...

Flume Replacement Use Cases Implemented in Apache NiFi

Sink/Source:   JMS

 

Source:   Files/PDF/PowerPoint/Excel/Word  Sink:  Files

 

Source:  Files/CSV  Sink:   HDFS/Hive/Apache ORC

 

Source:  REST/Files/Simulator   Sink:  HBase, Files, HDFS.    ETL with Lookups.

 

Flume Replacement - Lightweight Open Source Agents

 

If you need to replace local Log to Kafka agents or anything to Kafka or anything to anything with routing, transformation and manipulation.   You can use Edge Flow Manager deployed MiNiFi Agents available in Java and C++ versions.
