Benefits

• implemented locking to prevent multiple reads and writes

API

API is available at bazzline.net.

Future Improvements

• extend "filterBy"
  • $key and $value are optional to filter by key or by value
• take a look to bigdump
• take a look to reactphp/filesystem
• take a look to file wrapper
• implement "modifier" to easy up modifiying data before reading or writing
• if write (create/read) action is triggered, create a *.lock file to prevent multiple writings
  • or usd flock
• implement caching via proxy
  • simple two files storages injected
  • if number of changed itemes reaches limit, cache is written into real storage
• use a uuid generator for unique keys
  • use a temporary file
  • beeing even more pro, use php://temp
    • implement some kind of "intelligent" cache that counts the average size of an entry to determine the maximum number of entries before flushing the cache
