This is one possible simple, fast replacement for "Flafka".
You enter a few parameters and start ingesting data with or without schemas. Apache Flume had no Schema support. Flume did not support transactions.
Storing to files in files systems, object stores, SFTP or elsewhere could not be easier. Choose S3, Local File System, SFTP, HDFS or wherever.
Storing to Kudu/Impala (or Parquet for that manner could not be easier with Apache NiFi).
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
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.

*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-Schema/ta-p/247963

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.
