Talk:Protocol Standardization Efforts

I added this diagram to try to understand these pieces better.

• RDP is missing from my picture

Thinking about exnodes and erasure codings.

• L-Store writes extra erasure allocations.
• L-Store can write a LoRS compatible exnode file that excludes the erasure allocations.
  • LoRS compatibility
  • LoRS does not have access to L-Store's capability to regain a file.

Is this OK?

• The data user does not need (and probably should not be bothered with) to handle error recovery.
• data recovery, data warming, etc all are done by services/agents apart from the data consumer.
• So what user interface and development API are needed by the data users?
• command line tools
  • file movement
  • file system (some use the term namespace management) tools
    • list files, create directories, etc
• C/C++ API
  • just need my simple offsets and lengths
  • would like to read a vector of data blocks (non-blocked reads)
  • don't want to deal with erasure stuff at this point.
    • is there a nice way to recover from errors?
