Kafka的日志清理-LogCleanerKafka源码分析-汇总

LogCleaningInProgress, LogCleaningAborted,和LogCleaningPaused, 从字面上就很容易理解是什么意思,下面是源码中的注释: If a partition is to be cleaned While a partition is being cleaned, it can be requested to be aborted and paused. deleteHorizonMs: Long) { // create a new segment with the suffix .cleaned index = new OffsetIndex(indexFile, segments.head.baseOffset, segments.head.index.maxIndexSize) val cleaned (cleaned.baseOffset, segments.map(_.baseOffset).mkString(","), log.name)) log.replaceSegments(cleaned

    You can call track() on the NDArray for it to get tracked and // cleaned up at the end of the scope When the scope ends, the // GPU-resident NDArray will not get cleaned up, even though b goes out of const d = math.scope(() => { // CORRECT: e will get cleaned up when this inner scope ends. Since it is the // return value of this scope, it will not get cleaned up with this inner // {tensor: labelTensor, data: labelProvider} ]; // Wrap session.train in a scope so the cost gets cleaned

    大数据开发:Kafka日志加载与恢复

    2.遍历分区目录下的文件 根据文件后缀名分别进行处理,若文件后缀为.delete或.cleaned,则直接删除该文件。 后缀名是.delete表示该文件是需要被清除而还未执行删除操作,后缀名为.cleaned的文件表示是在日志清理操作第一阶段生成的临时文件。因此这两种类型的文件,在对日志段进行恢复操作时均直接删除。

    独家 | 探索性文本数据分析的新手教程(Amazon案例研究)

    作者使用Python中的lower()函数将文本转换为小写: df['cleaned']=df['reviews.text'].apply(lambda x: x.lower()) 删除数字和包含数字的单词 df['cleaned']=df['cleaned'].apply(lambda x: re.sub('\w*\d\w*','', x)) 删除标点符号 标点符号是英语中的标记,如逗号、连字符、句号等。 因此需要将其移除: df['cleaned']=df['cleaned'].apply(lambda x: re.sub('[%s]' % re.escape(string.punctuation), 最后,我们在数据中还有一些额外的空格,我们也一并删除它们: # Removing extra spaces df['cleaned']=df['cleaned'].apply(lambda x: re.sub(' +',' ',x)) 我们来看看清洗后的文本是什么样子的: for index,text in enumerate(df['cleaned'][35:40]):
