-ACID
+ |
ACID
|
-在可靠数据库管理系统（DBMS）中，事务（transaction）所应该具有的四个特性：原子性（Atomicity）、一致性（Consistency）、隔离性（Isolation）、和持久性（Durability）。

+ | A background write thread created when the database starts. The thread is used to flush dirty pages out of the database to a permanent device (such as a disk).
|
-bit
+ |
bit
|
-比特。计算机处理的最小的信息单位。比特用来表示二进制数字1或0，或者一种逻辑条件真或假。在物理上，比特表示一个电路上高或低的电压点或者磁盘上的磁化单程或其它。一个单独的比特位所传达的信息很少有意义的。然而，一个8位组却构成了一个字节，可用于表示如一个英文字母，十进制数字，或其它字符等多种类型的信息。
+ | Short for binary digit. The smallest unit of information handled by a computer. One bit expresses a 1 or a 0 in a binary numeral, or a true or false logical condition, and is represented physically by an element such as a high or low voltage at one point in a circuit or a small spot on a disk magnetized one way or the other. A single bit conveys little information a human would consider meaningful. A group of 8 bits, however, makes up a byte, which can be used to represent many types of information, such as a letter of the alphabet, a decimal digit, or other character.
|
-Bloom Filter
+ |
bloom filter
|
-布隆过滤器。由Howard Bloom在1970年提出的二进制向量数据结构，它具有很好的空间和时间效率，被用来检测一个元素是不是集合中的一个成员，这种检测只会对在集合内的数据错判，而不会对不是集合内的数据进行错判，这样每个检测请求返回有“在集合内（可能错误）”和“不在集合内（绝对不在集合内）”两种情况，可见Bloom filter是牺牲了正确率换取时间和空间。
+ | Bloom filter is a space-efficient binary vectorized data structure, conceived by Burton Howard Bloom in 1970, that is used to test whether an element is a member of a set. False positive matches are possible, but false negatives are not. In other words, a query returns either "possibly in set (possible error)" or "definitely not in set". In the cases, Bloom filter sacrificed the accuracy for time and space.
|
-CIDR
+ |
CIDR
|
-Classless Inter-Domain Routing，无类域间路由IP编址方案。CIDR摒弃传统的基于类（A类：8，B类：16，C类：24）的地址分配方式，允许使用任意长度的地址前缀，有效提高地址空间的利用率。CIDR表示方法：IP地址/网络ID的位数。比如192.168.23.35/21，其中“21”表示前面地址中的前21位代表网络部分，其余位代表主机部分。
+ | Acronym for classless inter-domain routing. Whereas classical network design for IPv4 sized the network prefix as one or more 8-bit groups, resulting in the blocks of Class A (8-bit), B (16-bit), or C (24-bit) addresses, CIDR allocates address space on any address bit boundary. A CIDR address is in the format of IP address/Number of bits in a network ID. For example, in 192.168.23.35/21, 21 indicates that the first 21 bits are the network prefix and others are the host ID.

|
-Freeze
+ |
freeze
|
-在事务ID耗尽时由AutoVacuum Worker进程自动执行的操作。openGauss会把事务ID记在行头，在一个事务取得一行时，通过比较行头的事务ID和事务本身的ID判断这行是否可见，而事务ID是一个无符号整数，如果事务ID耗尽，事务ID会跨过整数的界限重新计算，此时原先可见的行就会变成不可见的行，为了避免这个问题，Freeze操作会将行头的事务标记为一个特殊的事务ID，标记了这个特殊的事务ID的行将对所有事务可见，以此避免事务ID耗尽产生的问题。
+ | An operation automatically performed by the AutoVacuum Worker process when transaction IDs are exhausted. openGauss records transaction IDs in row headers. When a transaction reads a row, the transaction ID in the row header and the actual transaction ID are compared to determine whether this row is explicit. Transaction IDs are unsigned integers. If exhausted, transaction IDs are re-calculated outside of the integer range, causing the explicit rows to become implicit. To prevent such a problem, the freeze operation marks a transaction ID as a special ID. Rows marked with these special transaction IDs are explicit to all transactions.

savepoint
|
-保存点。是一种在关系数据库管理系统中实现子事务（也称为嵌套事务）的方法。在一个长事务中，可以把操作过程分成几部分，前面部分执行成功后，可以建一个保存点，若后面的执行失败，则回滚到这个保存点即可，无需回滚整个事务。保存点对于在数据库应用程序中实现复杂错误恢复很有用。如果在多语句事务中发生错误，则应用程序可能能够从错误中恢复（通过回滚到保存点）而无需中止整个事务。
+ | A savepoint marks the end of a sub-transaction (also known as a nested transaction) in a relational DBMS. The process of a long transaction can be divided into several parts. After a part is successfully executed, a savepoint will be created. If later execution fails, the transaction will be rolled back to the savepoint instead of being totally rolled back. This is helpful for recovering database applications from complicated errors. If an error occurs in a multi-statement transaction, the application can be restored by rolling back to the savepoint without terminating the entire transaction.

In a wide table containing a huge amount of data, a query usually only includes certain columns. In this case, the query performance of the row-store engine is poor. For example, a single table containing the data of a meteorological agency has 200 to 800 columns. Among these columns, only 10 are frequently accessed. In this case, a vectorized execution and column-store engine can significantly improve performance by saving storage space.
