Rows are organized into tables with a required primary key.\n\nhttps:\u002F\u002Fcwiki.apache.org\u002Fconfluence\u002Fdisplay\u002FCASSANDRA2\u002FPartitioners[Partitioning] means that Cassandra can distribute your data across multiple machines in an application-transparent matter. Cassandra will automatically repartition as machines are added and removed from the cluster.\n\nhttps:\u002F\u002Fcwiki.apache.org\u002Fconfluence\u002Fdisplay\u002FCASSANDRA2\u002FDataModel[Row store] means that like relational databases, Cassandra organizes data by rows and columns. The Cassandra Query Language (CQL) is a close relative of SQL.\n\nFor more information, see https:\u002F\u002Fcassandra.apache.org\u002F[the Apache Cassandra web site].\n\nIssues should be reported on https:\u002F\u002Fissues.apache.org\u002Fjira\u002Fprojects\u002FCASSANDRA\u002Fissues\u002F[The Cassandra Jira].\n\nRequirements\n------------\n- Java: see supported versions in build.xml (search for property \"java.supported\").\n- Python: for `cqlsh`, see `bin\u002Fcqlsh` (search for function \"is_supported_version\").\n\n\nGetting started\n---------------\n\nThis short guide will walk you through getting a basic one node cluster up\nand running, and demonstrate some simple reads and writes. For a more-complete guide, please see the Apache Cassandra website's https:\u002F\u002Fcassandra.apache.org\u002Fdoc\u002Ftrunk\u002Fcassandra\u002Fgetting-started\u002Findex.html[Getting Started Guide].\n\nFirst, we'll unpack our archive:\n\n  $ tar -zxvf apache-cassandra-$VERSION.tar.gz\n  $ cd apache-cassandra-$VERSION\n\nAfter that we start the server. Running the startup script with the -f argument will cause\nCassandra to remain in the foreground and log to standard out; it can be stopped with ctrl-C.\n\n  $ bin\u002Fcassandra -f\n\nNow let's try to read and write some data using the Cassandra Query Language:\n\n  $ bin\u002Fcqlsh\n\nThe command line client is interactive so if everything worked you should\nbe sitting in front of a prompt:\n\n----\nConnected to Test Cluster at localhost:9160.\n[cqlsh 6.3.0 | Cassandra 7.0-SNAPSHOT | CQL spec 3.4.8 | Native protocol v5]\nUse HELP for help.\ncqlsh>\n----\n\nAs the banner says, you can use 'help;' or '?' to see what CQL has to\noffer, and 'quit;' or 'exit;' when you've had enough fun. But lets try\nsomething slightly more interesting:\n\n----\ncqlsh> CREATE KEYSPACE schema1\n       WITH replication = { 'class' : 'SimpleStrategy', 'replication_factor' : 1 };\ncqlsh> USE schema1;\ncqlsh:Schema1> CREATE TABLE users (\n                 user_id varchar PRIMARY KEY,\n                 first varchar,\n                 last varchar,\n                 age int\n               );\ncqlsh:Schema1> INSERT INTO users (user_id, first, last, age)\n               VALUES ('jsmith', 'John', 'Smith', 42);\ncqlsh:Schema1> SELECT * FROM users;\n user_id | age | first | last\n---------+-----+-------+-------\n  jsmith |  42 |  john | smith\ncqlsh:Schema1>\n----\n\nIf your session looks similar to what's above, congrats, your single node\ncluster is operational!\n\nFor more on what commands are supported by CQL, see\nhttps:\u002F\u002Fcassandra.apache.org\u002Fdoc\u002Ftrunk\u002Fcassandra\u002Fdeveloping\u002Fcql\u002Findex.html[the CQL reference]. A\nreasonable way to think of it is as, \"SQL minus joins and subqueries, plus collections.\"\n\nWondering where to go from here?\n\n  * Join us in #cassandra on the https:\u002F\u002Fs.apache.org\u002Fslack-invite[ASF Slack] and ask questions.\n  * Subscribe to the Users mailing list by sending a mail to\n    user-subscribe@cassandra.apache.org.\n  * Subscribe to the Developer mailing list by sending a mail to\n    dev-subscribe@cassandra.apache.org.\n  * Visit the https:\u002F\u002Fcassandra.apache.org\u002Fcommunity\u002F[community section] of the Cassandra website for more information on getting involved.\n  * Visit the https:\u002F\u002Fcassandra.apache.org\u002Fdoc\u002Flatest\u002Fdevelopment\u002Findex.html[development section] of the Cassandra website for more information on how to contribute.\n","Apache Cassandra 是一个开源的分布式事务型数据库，能够在普通硬件或云基础设施上实现线性扩展和高容错性，同时保持高性能。其核心功能包括自动数据分区、多节点间的数据分布以及通过Cassandra查询语言（CQL）进行高效的数据操作，这使得它非常适合处理大规模数据集和需要高可用性的应用场景。Cassandra特别适合于那些对读写性能要求极高且能够容忍一定程度数据一致性的场景，如社交网络、物联网平台等。项目采用Java开发，并遵循Apache License 2.0许可协议。",2,"2026-06-11 02:58:32","top_language"]
