The in -depth understanding of the principles and applications of the TEDIS Father project
Overview:
Tedis is a distributed memory database system based on Java language. Its parent project Tributary is a stream processing framework for processing large -scale data streams.Tredis is built on the basis of the Tributary framework and is used to store and handle large -scale data streams.
Principle of tredis:
TREDIS uses an abstract concept called "data stream", which allows users to read and write data asynchronous and non -blocking.Tedis can process massive data streams to ensure the consistency and reliability of data.It realizes high availability and scalability by making data replication and data shards on multiple nodes.
1. Cache system: TREDIS can be used as an efficient cache system to reduce the pressure of the back -end database.It can store popular data in memory, quickly respond to reading requests, and improve the performance of the system.
2. Real -time analysis: Tredis can be used for real -time data analysis scenarios.It can extract useful information from the continuous influx of data streams, and use the tributary framework for real -time calculation and processing to achieve real -time analysis and real -time decision -making.
3. Message queue: Tredis can be used as a high throughput message queue system.It can process a large amount of messages and support the durable of the message to ensure the reliable transmission of the message.
TEDIS's programming code and configuration analysis:
The following is a sample code for creating and configured databases using TEDIS:
1. Create TEDIS instance:
import io.vedis.engine.*;
public class MyApp {
public static void main(String[] args) {
Tedis tedis = new Tedis();
}
}
2. Connect and configuration database:
import io.vedis.tedis.engine.Configuration;
public class MyApp {
public static void main(String[] args) {
Configuration config = new Configuration();
config.setHost("localhost");
config.setPort(6379);
Tedis tedis = new Tedis(config);
tedis.connect();
}
}
Among them, you can set the host address and port number of TEDIS to use the `Configuration` class, and then connect to the database through the method of` TEDIS.CONNECT () `.
3. Reading and writing operation of data:
import io.vedis.tedis.Tedis;
public class MyApp {
public static void main(String[] args) {
// Connect to the database
Tedis tedis = new Tedis();
// Data writing
tedis.set("key", "value");
// Data reading
String value = tedis.get("key");
System.out.println(value);
// Close the database connection
tedis.disconnect();
}
}
In the example code above, use the `Tedis.set (" Key "," Value ")` to write the data into the database and read the data with `TEDIS.GET (" Key ")`.
In summary, Tedis is a Java -based distributed memory database system. Its parent project Tributary is a big data stream processing framework.The principle of TEDIS is to achieve efficient data storage and processing through the concept of data flow, which can be applied to cache systems, real -time analysis and message queues.Through programming code and related configurations, you can create and configure the TEDIS database and perform data read and write operations.
