Dear HBase Dev Community, In our quest to pursue optimal performance for hbase when configuring root dir over cloud storage, we have been relying heavily on local cache using ephemeral SSD disks normally available on given cloud provider instance types.
Currently, our reference architecture for such use cases leverages file based BucketCache, but that has certain limitations, and we are now at early stages of testing an alternative approach using hdfs storage types and policies to mirror root dir content from S3 to hdfs dirs mounted on these ephemeral SSD disks. Additional technical details are documented here <https://docs.google.com/document/d/1XcUSBrsVTQLq_j_Tq6FrC_NRPiVNxdIU8gu2gDPT-eM/edit?tab=t.0> . So far in our PoC, we have implemented and tested the read/write from/to the different file system locations, we would like to continue this feature implementation in collaboration with the community, so we plan to open an umbrella jira ticket, together with individual subtasks for each functionality described in the document mentioned above. Comments and feedback are very welcome. Thanks, Wellington
