> When deserializing a row, we have a limit on amount of data we can read per cell. If an sstable is corrupted in a certain way, it may read many cells with extreme length leading to oom errors. When we read a row, it has a row size in the beginning. The idea is to limit the read size for a cell to the minimum of the max cell length and the remaining row size.
