Apache Doris, originally named Palo, is a distributed relational database based on column storage and MPP architecture. It offers a high performance, reliable, and scalable solution for data storage and analysis. Here is a basic guide to using Apache Doris.<\/p>\n

    \n
  1. To install and configure Doris, first download the installation package and unzip it. Then, in the unzipped directory, locate the “conf” folder and edit the “doris_fe.conf” and “doris_be.conf” files to configure parameters such as the listening address, port, storage directory, etc.<\/li>\n
  2. To start Doris: in the directory after decompression, run the command bin\/start_fe.sh to start the frontend service. Next, run the command bin\/start_be.sh on each backend node to start the backend service.<\/li>\n
  3. Create Database: Use Doris’ command line tool ‘doris’ to create a database. For example, use the command ‘doris create database test’ to create a database named test.<\/li>\n
  4. Create a table using Doris’s command line tool ‘doris’ command. For example, execute the command ‘doris -d test -e “create table t (id int, name varchar(20))”‘ to create a table named ‘t’ with two fields – id and name.<\/li>\n
  5. Load data: Use Doris’s command line tool, the doris command, to load data into a table. For example, by running the command “doris -d test -e ‘load data inpath ‘path\/to\/data.txt’ into table t'”, the data file data.txt will be loaded into table t.<\/li>\n
  6. Query data: Utilize Doris’s command-line tool to query data with the command “doris -d test -e “select * from t” to retrieve all data from table t.<\/li>\n
  7. Update data: Use Doris command line tool ‘doris’ to modify data. For example, running the command ‘doris -d test -e “update t set name=\u2018newname\u2019 where id=1″‘ will change the name field of the data with id 1 to ‘newname’.<\/li>\n
  8. Delete data: Use the Doris command line tool “doris” to remove data. For example, run the command “doris -d test -e “delete from t where id=1″” to delete data with id 1.<\/li>\n
  9. Optimize table: Improve the storage and query performance of a table using the Doris command-line tool, doris command. For example, running the command “doris -d test -e “optimize table t”” will optimize table t.<\/li>\n
  10. Stop Doris: In the directory after decompression, run the command bin\/stop_fe.sh to stop the front-end service. Then, run the command bin\/stop_be.sh on each backend node to stop the backend service.<\/li>\n<\/ol>\n

    This is a basic guide for using Apache Doris, where you can perform operations and configurations according to your specific needs. However, this is just a simple introduction. If you want to delve deeper into using Doris, you can refer to the official documentation or other related materials.<\/p>\n","protected":false},"excerpt":{"rendered":"
