必应词典为您提供incremental-base-backup的释义,网络释义: 基本备份;增量基本备份;
A base drive circuit for a power transistor includes a plurality of discrete current sources. A condition of the power transistor circuit, which is a function of the transistor current, is sensed and controls the number of discrete current sources that are activated.Mehl, Byron R....
To address this issue, this paper proposes an incremental mining algorithm called Pre-HUSPM, which leverages the concept of pre-large to insert new sequences into the dynamic database while preserving the discovered efficient sequence patterns. Furthermore, a novel threshold, denoted as S W U m...
Our stream replication slave server got out of sync so we need to base backup again. In case of big databases, can we do incremental backups with pg_basebackup? Is there any alternative? Here was a proposal:https://wiki.postgresql.org/wiki/Incremental_backup ...
【问题描述】执行BACKUP DATABASE INCREMENTAL LEVEL 1 format '/data/yasdb_back/backup/bak_20241120141704_lev1_diff'; 语句后触发报错。 【问题原因分析】 # 实施 level 1 级别的数据库备份时,必须存在 level 0 级别的备份(或者level 1级别的累积备份)。
HFile是一种适用于HBase的数据存储格式,它可以事先进行排序、压缩和索引,并且可以按照特定的分区键进行划分,以提高读写操作的效率。 当需要将大量数据导入HBase表中时,使用hbase.loadincrementalhfiles参数可以避免通过逐条插入数据的方式进行导入,从而大幅提高导入速度。通过预先生成HFile文件,并使用该参数进行装载,...
Only HBase 1.2.0-cdh5.15.2 and 2.4.13 are supported. Only the data of a table named in the format of TableName$ColumnFamilyName in OBKV can be migrated by an incremental synchronization task. To ensure the performance of a data migration task, we recommend that you migrate no more than...
In this research, we have used multiple item support tree (MIS-Tree for short) to mine frequent patterns and proposed algorithms that provide (1) a complete facility of multiple support tuning (MS Tuning), and (2) maintenance of MIS-tree with incremental update of database. In a recent ...
LoadIncrementalHFiles的初始化过程比较简单,主要是对hbase admin等对象的初始化: Initialize方法 doBulkLoad doBulkLoad方法执行以下步骤: 1. 创建线程池 创建用于bulkload的线程池, 线程池大小由参数hbase.loadincremental.threads.max控制,默认为当前机器的core数量。源码如下: ...
