TiKV is an open-source, distributed, and transactional key-value database. Unlike other traditional NoSQL systems, TiKV not only provides classical key-value APIs, but also transactional APIs with ACID compliance. Built in Rust and powered by Raft, TiKV was originally created byPingCAPto complemen...
One example is Microsoft Excel. In Excel, when Scroll Lock is enabled, pressing the arrow keys on your keyboard scrolls the selected cells without changing the active cell. This can be useful when working with large spreadsheets. How can I enable or disable the Scroll Lock feature?
With PD and carefully designed Raft groups, TiKV excels in horizontal scalability and can easily scale to 100+ TBs of data. Consistent distributed transactions Similar to Google's Spanner, TiKV supports externally-consistent distributed transactions. Coprocessor support Similar to Hbase, TiKV implements...
1 row in set (0.00 sec) 我们看到Key那一栏,可能会有4种值,即'啥也没有','PRI','UNI','MUL' 1. 如果Key是空的, 那么该列值的可以重复,表示该列没有索引, 或者是一个非唯一的复合索引的非前导列 2. 如果Key是PRI, 那么该列是主键的组成部分 ...
