> *Current problems:*
> 1. Freon does not support big files larger than 2GB because it use an int
> type "keySize" parameter and also "keyValue" buffer size.
> 2. Freon allocates a entire buffer for each key at once, so if the key size
> is large and the concurrency is high, freon will report OOM exception
> frequently.
> 3. Freon lacks option such as "--validateWrites", thus users cannot manually
> specify that verification is required after writing.
> *Some solutions:*
> 1. Use a long type "keySize" parameter, make sure freon can support big
> files larger than 2GB.
> 2. Use a small buffer repeatedly than allocating the entire key-size buffer
> at once, the default buffer size is 4K and can be configured by "–bufferSize"
> parameter.
> 3. Add a "--validateWrites" option to Freon command line, users can provide
> this option to indicate that a validation is required after write.
