Real Time Streaming Cheatsheet
This cheatsheet is a reference guide for anyone getting started with real time data streaming processing, time series databases, Spark, Beam, Kafka, and Flink. It covers the basic concepts, topics, and categories related to these technologies.
Real Time Data Streaming Processing
Real time data streaming processing is the process of processing data in real time as it is generated. It involves the use of various technologies and techniques to process data as it is generated, rather than waiting for it to be stored in a database or other storage system.
- Data Streaming: The process of generating and processing data in real time.
- Real Time Processing: The ability to process data as it is generated.
- Data Pipeline: The process of moving data from one system to another.
- Data Processing: The process of transforming data from one format to another.
- Data Analytics: The process of analyzing data to gain insights and make decisions.
- Apache Kafka: A distributed streaming platform that allows you to publish and subscribe to streams of records.
- Apache Flink: A distributed processing engine for streaming data.
- Apache Spark: A distributed computing system for processing large datasets.
- Apache Beam: A unified programming model for batch and streaming data processing.
Time Series Databases
Time series databases are databases that are optimized for storing and querying time series data. They are designed to handle large volumes of data and provide fast, efficient access to that data.
- Time Series Data: Data that is recorded over time.
- Data Points: Individual data values that are recorded over time.
- Time Series Database: A database that is optimized for storing and querying time series data.
- Data Retention: The length of time that data is stored in a time series database.
- Data Aggregation: The process of summarizing time series data.
- InfluxDB: An open source time series database.
- TimescaleDB: An open source time series database built on top of PostgreSQL.
- OpenTSDB: An open source time series database built on top of HBase.
Apache Kafka is a distributed streaming platform that allows you to publish and subscribe to streams of records. It is designed to handle large volumes of data and provide fast, efficient access to that data.
- Topics: A category or feed name to which records are published.
- Partitions: A topic can be divided into multiple partitions, each of which can be processed independently.
- Producers: Applications that publish records to Kafka topics.
- Consumers: Applications that subscribe to Kafka topics and process records.
- Brokers: Kafka servers that manage the storage and replication of records.
- Create a topic:
bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic my-topic
- List topics:
bin/kafka-topics.sh --list --zookeeper localhost:2181
- Start a producer:
bin/kafka-console-producer.sh --broker-list localhost:9092 --topic my-topic
- Start a consumer:
bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic my-topic --from-beginning
Apache Flink is a distributed processing engine for streaming data. It is designed to handle large volumes of data and provide fast, efficient processing of that data.
- DataStreams: A stream of data that can be processed in real time.
- Operators: Functions that can be applied to DataStreams to transform or aggregate data.
- Windowing: The process of dividing a DataStream into windows and processing each window independently.
- Stateful Processing: The ability to maintain state across multiple events in a DataStream.
- Start a Flink cluster:
- Submit a Flink job:
./bin/flink run <job-jar>
Apache Spark is a distributed computing system for processing large datasets. It is designed to handle large volumes of data and provide fast, efficient processing of that data.
- Resilient Distributed Datasets (RDDs): A distributed collection of data that can be processed in parallel.
- Transformations: Functions that can be applied to RDDs to transform or aggregate data.
- Actions: Functions that trigger the execution of transformations and return results.
- Spark SQL: A module for working with structured data using SQL.
- Start a Spark cluster:
- Submit a Spark job:
Apache Beam is a unified programming model for batch and streaming data processing. It provides a simple, consistent API for processing data in both batch and streaming modes.
- Pipelines: A sequence of data processing steps.
- Transforms: Functions that can be applied to data in a pipeline to transform or aggregate data.
- Sources: Input data for a pipeline.
- Sinks: Output data for a pipeline.
- Run a Beam pipeline:
./gradlew run -Pargs="--runner=DirectRunner"
