2.2 Understanding Big Data Analytics Systems Architecturally
Big data analytics system plays the role of integrating, organizing and analyzing a huge data set, which is not only a simple data warehouse, but also a complex system covering multiple dimensions of information such as system data and business data.
The core task of a big data analysis system is to realize the mining and analysis of data under a unified data framework. This means that numerous components and complex functions are involved, so how to skillfully combine these components organically becomes a crucial aspect in the construction process of the system. This subsection will explore the component structure of the big data analytics system, analyze the synergy between the components, and how to achieve efficient data processing and visualization display in this multi-layered and multi-functional system.
2.2.1 Understanding the architecture of big data analytics systems
With the dramatic expansion of data size and diversity, building an efficient and scalable big data analytics system has become critical. In order to deeply understand the operation of this mammoth system, this section will lead readers to explore its architecture together, from data collection to the final presentation of insights, revealing how a big data analytics system can discover valuable information in the vast and diverse ocean of data. As shown in the figure.
1. Data acquisition layer: connecting diverse data sources
The data collection layer is the foundation of the big data analysis platform, which is directly related to the acquisition and integration of data. The bottom layer is various types of data sources, including various business data, user data, log data, and so on. To ensure comprehensiveness, both traditional ETL offline acquisition and real-time acquisition are often used. The goal of this layer is to integrate fragmented data from all corners to form a comprehensive and coherent data set.
2. Data storage and processing layer: strong support for data
With the underlying data, the next step is to store the data in a suitable persistent storage layer (e.g. Hive Data Warehouse) and preprocess the data according to different needs and scenarios. This includes OLAP, machine learning, and many other forms. At this level, the data is further processed to ensure the quality, availability and security of the data, providing a solid foundation for subsequent deeper analysis.
3. Data analysis layer: unlocking the deeper value of data
At the data analysis layer, reporting systems and BI analytics systems play a key role. Data is simply processed at this stage and then analyzed and mined at a deeper level. The task of this layer is to extract valuable information from the huge amount of data to provide strong support for enterprise decision-making. At this stage, data becomes more intelligent and easy to understand.
4. Data application layer: transforming data into business insights
Ultimately, data is categorized into different categories of applications based on business needs. This includes forms such as data reports, dashboards, digital big screens, and just-in-time queries. The data application layer is the output of the entire data analysis process and the key to demonstrate the value of data externally. Through visualization, the analysis results are vividly presented to the end user to help business decisions.
In-depth understanding of the system architecture is not only a matter of technology, but also requires a deep understanding of business requirements and user expectations. Only through a reasonably designed architecture, from data collection to final application, can we realize comprehensive mining and deep analysis of data.
2.2.2 Designing the core modules of a big data analytics system
The core modules for designing a big data analysis system cover data acquisition, data storage, data analysis, and data services, etc. These key modules work together to build a complete and efficient big data analysis system. As shown in the figure.
1. Data Acquisition
As the first step of the system, the data collection module undertakes the task of assembling information data from various business self-systems. The system chooses to support Kafka, Flume and traditional ETL collection tools to ensure efficient processing and integration of diverse data sources.
2. Data storage
The data storage module adopts an integrated storage scheme that combines Hive, HBase, Redis and MySQL to form a distributed storage system that supports massive data. This integrated storage model ensures efficient management and retrieval of large-scale data.
3. Data analysis
The data analytics module is the core engine of the system, supporting both traditional OLAP analytics and conventional Spark-based machine learning algorithms. This enables the system to dig deeper into huge datasets to discover potential values and trends, providing strong support for decision-making.
4. Data services
The data service module is the hub of the system, providing unified management and scheduling of data resources. Through data services, the system realizes the overall governance of data, enabling the flow, storage and analysis of data in an orderly and efficient manner. At the same time, it provides data services to the outside world, providing a standardized interface and access to other systems and applications.
The synergy of these core modules enables the big data analytics system to form an organic and perfect architecture from data collection to storage, to analysis, and finally to provide services to the outside world. By integrating the functions of each module, the system is able to cope with changing data environments and provide users with efficient, reliable and flexible big data analysis solutions.
2.3 Realization of a big data analysis system
The process of implementing a big data analytics system mainly covers the following key steps, including data collection, data integration, data processing and data visualization. This series of steps constitutes what is commonly referred to as a one-stop big data analytics platform.
On this platform, data acquisition is responsible for obtaining raw data from multiple sources, and subsequent data integration aggregates this data and ensures format consistency. Next, the data processing phase performs data cleansing, transformation and processing to bring the data up to analyzable standards.
Ultimately, through data visualization, users are able to understand and explore data in an intuitive way, providing strong support for decision-making. This standard process provides the basic framework for designing and implementing a big data analytics system that can efficiently handle large data sets and meet diverse analytical needs.
2.3.1 Data acquisition
Data collection is the crucial first step in a big data analysis system, which plays a key role in the system's access to the source of information. At this stage, the system collects raw data extensively and efficiently through various channels and technologies to lay the foundation for subsequent analysis and processing. The data collection process covers diverse data sources from sensors, logs, external databases to online platforms, ensuring that the system is able to obtain comprehensive and multi-dimensional information.
In this subsection, we have specifically designed an application in order to simulate a data collection scenario, whose main function is to generate simulated data as raw data and send this data to the Kafka messaging middleware.
Here is a simple application written in Java to generate simulated movie data to be sent concurrently to Kafka.In this example, we use the Java client library for Apache Kafka. The specific dependencies are shown in the code.
<dependency> <groupId></groupId> <artifactId>kafka_2.13</artifactId> <version>3.4.0</version> </dependency>
The detailed steps to implement sending simulated data to Kafka are shown in the code. Here are some key implementation details:
- Kafka Configuration: In the code, you need to configure parameters such as Kafka's server address (), serializer for key and value, etc. in order to establish a connection to the Kafka cluster.
- Creating a KafkaProducer: Use the configuration information to create a KafkaProducer object, which is responsible for sending data to the Kafka cluster.
- Generate simulation data: In a loop, use your data generation logic to generate simulated data. This may include creating data in JSON format, setting data fields, simulating dates, etc.
- Building a ProducerRecord: Use the generated mock data to construct a ProducerRecord object, which includes the target subject, key (if any), and data to be sent.
- Send data: Use the send method of KafkaProducer to send the ProducerRecord to the Kafka topic.
- Control send rate (optional): In a loop, you can control the rate at which data is generated and sent to avoid sending it too often by, for example.
The implementation is shown in the code.
@Slf4j public class MovieDataProducer { public static void main(String[] args) { sendRawData(); } private static void sendRawData() { // Kafka Server Address String kafkaBootstrapServers = "localhost:9092"; // Kafka Themes String kafkaTopic = "ods_movie_data"; // Creating a Kafka Producer Configuration Properties properties = new Properties(); ("", kafkaBootstrapServers); ("", ""); ("", ""); // Creating a Kafka Producer try { Producer<String, String> producer = new KafkaProducer<>(properties) // Generate and send analog movie data for (int i = 1; i <= 1000; i++) { String movieData = generateMovieData(i); (new ProducerRecord<>(kafkaTopic, (i), movieData)); // Printing of sent data information (optional) ("Sending data to Kafka:" + movieData); // Controls the rate of data generation, e.g. once per second. (1000); } } catch (InterruptedException e) { ("Send data to Kafka abnormalities:{}", e); } } // Generate analog movie data private static String generateMovieData(int rank) { String[] countries = {"America.", "China.", "India.", "England.", "Japan."}; String[] genres = {"Action.", "Plot.", "Comedy.", "Sci-Fi.", "Adventure."}; LocalDate releaseDate = () .minusDays(new Random().nextInt(180)); DateTimeFormatter formatter = ("yyyy-MM-dd"); MovieData movieData = new MovieData( rank, "Movie" + rank, (formatter), countries[new Random().nextInt()], genres[new Random().nextInt()], 5 + 5 * (), new Random().nextInt(1000000) ); // Returns a string result String result = ""; // Using the Jackson Library to Convert Objects to JSON Strings try { ObjectMapper objectMapper = new ObjectMapper(); result = (movieData); } catch (Exception e) { ("conversions JSON An exception occurs in the string:{}", e); } return result; } // Movie Data Class @Data private static class MovieData { private int rank; private String name; private String releaseDate; private String country; private String genre; private double rating; private int playCount; public MovieData(int rank, String name, String releaseDate , String country, String genre , double rating, int playCount) { this.rank = rank; this.name = name; this.releaseDate = releaseDate; this.country = country; this.genre = genre; this.rating = rating; this.playCount = playCount; } } }
Make sure to replace localhost:9092 and ods_movie_data with the address of the Kafka server you are actually using and the theme name. This simple Java application generates mock movie data containing fields such as movie rank, movie name, release date, country of production, genre, rating, number of plays, etc. and sends it to the specified Kafka topic.
2.3.2 Data storage
Data storage plays a key role in big data analytics system, which not only needs to provide a highly reliable storage mechanism, but also needs to be intelligently partitioned according to business requirements for subsequent offline analysis and query. In the current scenario, we are facing a batch of real-time streaming data that keeps coming in, which needs to be effectively stored in Hive after real-time processing to meet the subsequent offline analysis requirements.
In order to ensure the timeliness of the data, we plan to store the data at 5-minute intervals as a time window, which will not only help improve query efficiency, but also better support time-based analytics. To achieve this goal, we will use Apache Flink as our stream processing engine to consume and process data in Kafka Topic in real-time through its integration with Kafka. The specific implementation flow is shown in Fig.
1. Environmental dependence
When consuming data from a Kafka cluster, Flink needs to introduce a series of dependencies to ensure the smooth operation of the system.
In order to achieve efficient consumption of data in a Kafka cluster, we need to introduce Flink-related dependencies. These dependencies include not only the core Flink libraries, but also libraries that connect and interact with Kafka. The specific dependencies are shown in the code.
<dependency> <groupId></groupId> <artifactId>flink-connector-filesystem_2.12</artifactId> <version>${}</version> </dependency> <dependency> <groupId></groupId> <artifactId>flink-connector-kafka-0.11_2.12</artifactId> <version>${}</version> </dependency> <dependency> <groupId></groupId> <artifactId>flink-streaming-java_2.12</artifactId> <version>${}</version> </dependency>
2. Read data
Write Flink code to consume Kafka Topic and store data directly to HDFS without additional logical processing for subsequent data preprocessing using MapReduce. Specific implementation is shown in the code.
@Slf4j public class FlinkTemplateTask { public static void main(String[] args) { // Check that the input parameters meet the requirements if ( != 3) { ("kafka(server01:9092), hdfs(hdfs://cluster01/data/), flink(parallelism=2) must be exist."); return; } String bootStrapServer = args[0]; String hdfsPath = args[1]; int parallelism = (args[2]); // Creating a Flink Streaming Environment StreamExecutionEnvironment env = (); (5000); (parallelism); (); // Reading data from Kafka DataStream<String> transction = (new FlinkKafkaConsumer010<>("ods_movie_data" , new SimpleStringSchema(), configByKafkaServer(bootStrapServer))); // Store to HDFS BucketingSink<String> sink = new BucketingSink<>(hdfsPath); // Customize the name of the file stored on HDFS with hours and minutes to make it easier to calculate the policy later on (new JDateTimeBucketer<String>("HH-mm")); (1024 * 1024 * 4); // Size 5MB (1000 * 30); // Time 30s (sink); // Executing Flink Tasks ("Kafka2Hdfs"); } // Setting up the Kafka consumer configuration private static Object configByKafkaServer(String bootStrapServer) { Properties props = new Properties(); ("", bootStrapServer); ("", "test_bll_group"); ("", "true"); ("", "1000"); ("", ""); ("", ""); return props; } }
A special note here is that we set the time window to be short and check every 30 seconds. If no data arrives within the time window of the batch, we will generate a file and save it to HDFS.
In addition, we have rewritten DateTimeBucketer to create JDateTimeBucketer.The logic of this tweak is not complicated, it just adds a year-month-day/hour-minute file generation path to the original method. For example, the path generated on HDFS might be: xxxx/2023-10-10/00-00. This tweak helps to better organize and manage the generated files, making them more consistent with the time and date structure.
3. File naming strategy
In this step, we need to preprocess the files that have been stored on HDFS. The processing logic is as follows: for example, if the current time is 2023-10-10 14:00, we need to process the last 5 minutes of the day, 13:55, 13:56, 13:57, 13:58, and 13:59, and load them into one of Hive's last 5 minutes partitions. To accomplish this, we need to generate a logical policy collection with HH-mm as the key and the 5 nearest files to it as the value.This collection will be used for data preprocessing and merging. The implementation is shown in the code.
public class DateRangeStrategy { public static void main(String[] args) { getFileNameStrategy(); } // Generation Strategy private static void getFileNameStrategy() { for (int i = 0; i < 24; i++) { for (int j = 0; j < 60; j++) { if (j % 5 == 0) { if (j < 10) { if (i < 10) { if (i == 0 && j == 0) { ("0" + i + "-0" + j + "=>23-59,23-58,23-57,23-56,23-55"); } else { if (j == 0) { String tmp = ""; for (int k = 1; k <= 5; k++) { tmp += "0" + (i - 1) + "-" + (60 - k) + ","; } ("0" + i + "-0" + j + "=>" + (0, () - 1)); } else { String tmp = ""; for (int k = 1; k <= 5; k++) { if (j - k < 10) { tmp += "0" + i + "-0" + (j - k) + ","; } else { tmp += "0" + i + "-" + (j - k) + ","; } } ("0" + i + "-0" + j + "=>" + (0, () - 1)); } } } else { if (j == 0) { String tmp = ""; for (int k = 1; k <= 5; k++) { if (i - 1 < 10) { tmp += "0" + (i - 1) + "-" + (60 - k) + ","; } else { tmp += (i - 1) + "-" + (60 - k) + ","; } } (i + "-0" + j + "=>" + (0, () - 1)); } else { String tmp = ""; for (int k = 1; k <= 5; k++) { if (j - k < 10) { tmp += i + "-0" + (j - k) + ","; } else { tmp += i + "-" + (j - k) + ","; } } (i + "-0" + j + "=>" + (0, () - 1)); } } } else { if (i < 10) { String tmp = ""; for (int k = 1; k <= 5; k++) { if (j - k < 10) { tmp += "0" + i + "-0" + (j - k) + ","; } else { tmp += "0" + i + "-" + (j - k) + ","; } } ("0" + i + "-" + j + "=>" + (0, () - 1)); } else { String tmp = ""; for (int k = 1; k <= 5; k++) { if (j - 1 < 10) { tmp += i + "-0" + (j - k) + ","; } else { tmp += i + "-" + (j - k) + ","; } } (i + "-" + j + "=>" + (0, () - 1)); } } } } } } }
4. Data loading
When the data is ready, we can load the pre-processed files on HDFS into the corresponding tables directly with the help of Hive's LOAD command. The specific implementation is shown in the code.
LOAD DATA INPATH '/data/hive/hfile/data/min/2023-10-10/14-05/' OVERWRITE INTO TABLE game_user_db.ods_movie_data PARTITION(day='2023-10-10',hour='14',min='05');
When executing a command, if the file does not exist it may cause a loading error. Therefore, before loading the HDFS path, we can determine whether the path exists or not. The implementation is shown in the code.
#!/bin/bash # HDFS data path hdfs_path='/data/hive/hfile/data/min/2023-10-10/14-05/' # Check if the HDFS path exists if hdfs dfs -test -e "$hdfs_path"; then # If present, perform the load operation echo "Performing a Hive Data Load Operation" hive -e "LOAD DATA INPATH '$hdfs_path' OVERWRITE INTO TABLE game_user_db.ods_movie_data PARTITION(day='2023-10-10',hour='14',min='05');" else echo "HDFS path: ['$hdfs_path'] does not exist" fi
It is important to note that this script first checks if the HDFS path exists, and if it does, it performs the load operation, otherwise it outputs an error message. This avoids loading errors caused by non-existent files.
2.3.3 Data analysis
Data analysis is a science, through the organization, cleaning and analysis of data, we can dig out the laws and trends hidden behind the huge data. The continuous development of data analysis tools makes this process more efficient. The application of statistics, machine learning, artificial intelligence and other technologies enables us to understand the information in the data more deeply. Through data visualization techniques, we are able to turn abstract data into intuitive charts and images, making it easier to understand and convey the meaning of the data.
1. Analyze the film year histogram
In order to generate a histogram of movie years, we can do this by aggregating the movie year data. The implementation is shown in the code.
-- Year of movie SELECT release_date, COUNT(1) AS pv FROM ods_movie_data WHERE day = '2023-10-10' GROUP BY release_date;
Execute the above code and analyze the results as shown in the figure.
2. Analyze film genre fan charts
In order to generate a fan chart of movie types, we can do this by aggregating the movie type data. The implementation is shown in the code.
-- Movie Type SELECT genre, COUNT(1) AS pv FROM ods_movie_data WHERE day = '2023-10-10' GROUP BY genre;
Execute the above code and analyze the results as shown in the figure.
3. Analyze the movie rating scatterplot
In order to generate a scatterplot of movie ratings, we can do this by aggregating the movie rating data. The implementation is shown in the code.
-- movie rating SELECT rating, COUNT(1) AS pv FROM ods_movie_data WHERE day = '2023-10-10' GROUP BY rating;
Execute the above code and analyze the results as shown in the figure.
