这种方法是缺陷是，如果使用率阀值没有微小的增量，则一些粒度级的数据可能会丢失，并且阀值下方的内存使用率模式将变为不可见。
The downside of this approach is that without extremely small increments in the usage threshold, some granularity of data can be lost and patterns of memory usage below the threshold become invisible.

您可以定期地削减全面基线，也可以更新增量以达到全面，这样，增量基线就不需要处理太多数据。

This is, of course, simply the incremental database backups problem.
用函数需要处理的所有数据一次性调用函数，始终优于多次调用函数，并以增量的方式为其提供数据。
It's always better to call a function once with all the data it needs to process rather than to call it multiple times and to feed it data incrementally.
它们可以发送增长增量、最大容量、初始大小等特征数据。
They have the ability to send characteristics of the growth increment, maximum size, initial size, and so on.
通过增量解组(incrementalunmarshalling)并提供xget方法来访问内置的模式数据类型，XMLBeans取得了较好的性能。
XMLBeans scores well on performance by doing incremental unmarshalling and providing xget methods to access built-in schema data types.
有些数据格式还提供m(度量)坐标，这通常用于时间增量。
Some data formats also provide an m (measure) coordinate, most often used for time increments.
Percolator是专门针对处理增量更新而设计，但不是用于取代大多现有的数据处理解决方案。
Percolator was built specifically for incremental processing and is not intended to supplant existing solutions for most data processing tasks.
delta备份：delta备份是对最近一次成功的备份(包括全备份、增量备份和delta备份)以来被修改了的数据的备份。
Delta backup: delta backup is backup of only the data that has changed since the last successful full, incremental, or delta backup.
数据库序列的增量应该设置为increment_size参数值。
Your database sequence should increment by the increment_size parameter value.
在处理像数据仓库环境中数据库那样的巨型数据库方面，Oracle和DB 2都提供了增量和差异备份，避免复制未更改的数据页。

Pattern: Use scripts and database to apply incremental changes in each target environment.
元数据不是增量复制的，而是每次都一一完全复制。
This metadata is not incremental; it is a full copy each and every time.
默认情况下，DB 2数据库没有被配置为支持增量备份，因为为了使DB 2能执行这类备份，会对运行时性能产生一个非常小的影响。
By default, a DB2 database is not configured for incremental backups because there is a very minimal impact on runtime performance that's incurred to enable DB2 to perform this kind of backup.

增量备份在事务比较少的数据库上非常高效，因为您仅保存最后备份之后发生的更改，而不是数据库中的所有页。
An incremental backup is more efficient for databases with a small amount of transactions because you are saving only the pages that have changed since the last backup, not every page in the database.
