摘要： Embodiments are directed towards employing compressed journaling for event tracking files for metadata recovery and replication. Event data and related metadata are received from one or more client devices. When a feature within the received metadata is detected that is previously unwritten to a journal, then the previously unwritten feature is written to the journal. Further, any feature is detected for the received event data that is determined to be different from a feature associated with an immediately preceding event data that is written in the journal, then the detected different feature is identified in the journal. In one embodiment, the identification employs writing to the journal an effective feature record that may employ indices identifying the different feature. The received event data is also written to the journal and may further employ string arguments to minimize recording of redundant information into the journal.
摘要翻译：实施例针对使用压缩日志记录用于事件跟踪文件以用于元数据恢复和复制。事件数据和相关元数据从一个或多个客户端设备接收。当检测到接收到的元数据中的特征先前未被写入日志时，则先前未写入的特征被写入日志。此外，对于所接收到的事件数据检测到任何特征，该特征被确定为不同于与记录在日志中的紧接在前的事件数据相关联的特征，然后在日志中识别出检测到的不同特征。在一个实施例中，标识采用向日志写入有效特征记录，其可以采用标识不同特征的索引。收到的事件数据也写入日志，并可能进一步使用字符串参数来最大限度地减少冗余信息记录到日志中。
