Abstract
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.
