Timeplus is a streaming-first data analytics platform. It provides powerful end-to-end capabilities, leveraging the open source streaming engine Proton, to help teams process streaming and historical data quickly and intuitively, accessible for organizations of all sizes and industries. It enables data engineers and platform engineers to unlock streaming data value using SQL.

​
Upstash Kafka Setup

Create a Kafka cluster using Upstash Console or Upstash CLI by following Getting Started. Create two topics by following the creating topic steps. Let’s name the first topic input, since we are going to stream from this topic to Timeplus. The name of the second topic can be output. This one is going to receive the stream from Timeplus.

​
Create a Kafka Source in Timeplus

Besides the Open Source engine Proton, Timeplus also offers Timeplus Cloud, a fully managed cloud service with SOC2 Type 1 Security Compliance. To use the Timeplus Cloud, create an account and setup a new workspace. After creating the workspace, click the Data Ingestion in the menu bar. Click on Add Data
Choose the Apache Kafka source.
In the wizard, specify the Kafka Brokers as <name>-<region>-kafka.upstash.io:9092. Enable all security options and choose SASL SCRAM 256 and type the username and password.
Click the Next button. In the dropdown list, you should be able to see all available Kafka topics. Choose the input topic. Leave the JSON as the Read As option. Choose Earliest if you already create messages in the topic. Otherwise use the default value Latest.
Click the Next button, it will start loading messages in the input topic. Let’s go to Upstash UI and post a JSON message in input topic: 
{
  "requestedUrl": "http://www.internationalinteractive.name/end-to-end",
  "method": "PUT",
  "ipAddress": "186.58.241.7",
  "requestDuration": 678
}
Right after the message is posted, you should be able to see it in the Timeplus UI. Since you specify JSON format, those 4 key/value pairs are read as 4 columns. Choose a name for the data stream, say input and accept the default options.
Click the Next button to review the settings. Finally, click the Create the source button.
There will be a green notification message informing you the source has been created.

​
Run Streaming SQL

Click the Query menu on the left and type the streaming SQL as: 
select * from input
Go back to the Upstash UI to post a few more messages to the topic and you can see those live events in the query result.

​
Apply Streaming ETL and Write Data to Upstash Kafka

Cancel the previous streaming SQL and use the following one to mask the IP addresses. 
select now64() AS time, requestedUrl,method,lower(hex(md5(ipAddress))) AS ip
from input where _tp_time > earliest_ts()
Click the Send as Sink button. Use the default Kafka output type and specify the broker, topic name(output), user name and password.
Click the Send button to create the sink. Go back to the Upstash UI. Create a few more messages in input topic and you should get them available in output topic with raw IP addresses masked.
Congratulations! You just setup a streaming ETL with a single line of SQL in Timeplus Cloud. Learn more about Timeplus by visiting https://docs.timeplus.com/ or join https://timeplus.com/slack
