> There are a number of properties in the yaml that are "in_mb", however resolve to bytes
when calculated in {{DatabaseDescriptor.java}}, but are stored in int's. This means that their
maximum values are 2047, as any higher when converted to bytes overflows the int.
> Where possible/reasonable we should convert these to be long's, and stored as long's.
If there is no reason for the value to ever be >2047 we should at least document that as
the max value, or better yet make it error if set higher than that. Noting that although it's
bad practice to increase a lot of them to such high values, there may be cases where it is
necessary and in which case we should handle it appropriately rather than overflowing and
surprising the user. That is, causing it to break but not in the way the user expected it
to :)
> Following are functions that currently could be at risk of the above:
> {code:java|title=DatabaseDescriptor.java}
> getThriftFramedTransportSize()
> getMaxValueSize()
> getCompactionLargePartitionWarningThreshold()
> getCommitLogSegmentSize()
> getNativeTransportMaxFrameSize()
> # These are in KB so max value of 2096128
> getBatchSizeWarnThreshold()
> getColumnIndexSize()
> getColumnIndexCacheSize()
> getMaxMutationSize()
> {code}
> Note we may not actually need to fix all of these, and there may be more. This was just
from a rough scan over the code.
