According to the paper, that's one of the goals of the project:
"In the future, we plan to investigate several natural extensions to Mach. Specifically, we believe that metrics workloads exhibit similar characteristics to other observability data types: logs, events, and traces [20, 21]. For example, integrating log data will require the investigation of fundamental design considerations (e.g., trading off compression speed with size, enabling search over compressed data), whereas supporting traces might necessitate the development of entirely new data models (e.g., graph-based approaches to facilitate root cause analysis). Our ultimate goal is to establish Mach as a unifying storage engine for observability workloads."
Are reposts ok? If a story has not had significant attention in the last year or so, a small number of reposts is ok. Otherwise we bury reposts as duplicates.
Sometimes the moderators also invite users to resubmit (although this was not the case here).
