---------------------------------
Summary: File backend for the SegmentMK
Key: OAK-788
URL: https://issues.apache.org/jira/browse/OAK-788
Project: Jackrabbit Oak
Issue Type: Sub-task
Components: core
Reporter: Jukka Zitting
Assignee: Jukka Zitting
The SegmentMK now has two backends: one in-memory and the other based on
MongoDB. Since MongoDB isn't readily available everywhere and the in-memory
backend obviously isn't suited for production use, it would be useful to have
an additional SegmentMK backend based on just the local file system.
Inspired by, though not directly based on, the proprietary TarPM in CRX, I
propose to implement such a backend using the tar file format as the basis.
Unlike the MongoDB backend or the original TarPM, such a "TarMK" backend would
be designed primarily for optimum performance on a *single-node* deployment,
i.e. without support for clustering. A typical deployment could be replicated
set of independent copies of a repository, designed for massively parallel
read-only or mostly-read workloads.
