Java out-of-heap memory (direct memory unmanaged memory)The benefits of out-of-heap memory are: Can be extended to a larger memory space. For example, more than 1TB or even larger than main memory space. In theory, the GC pause time can be reduced. can be shared among processes , reducing object duplication between JVMs , making it easier to implement a split deployment of a JVM. Its persistent storage enables fast reboots while also re

power, If the 1TB data above these three elements do not include the sorting operation, the read operation can be completed in 10 milliseconds, perhaps the real-time sequencing of large amounts of data is possible, but the current computer is absolutely no such ability.So how do we solve the problem of real-time sequencing of massive data in real-world scenarios? In order to solve this problem we must have a bit of reverse thinking consciousness, a w

Simple sortingInternal sort and external sort internal sort is if you have 2GB of memory just have 2GB below the data need to sort so just to store all the data in memory to be sorted this is the internal sort and the opposite of the external sort is that you have 1TB of data to be To sort but you have 2GB of memory when the memory does not hold the data, you need to start the external sort.Stable and unstable sort the relative position of any two eq

analyze the information. one buffer per message readerObviously, some of the information needs to be stored in a buffer. The simple implementation is simply that there is a buffer within each of the message reader's internals. However, how big should that buffer be? It will need to be large enough to allow information to be stored for greater allowable. So that if the larger allowable information is 1M, then the internal buffers in each message reader will require at least 1M of space. Whe

. Bigger filesystem/file sizes Currently, ext3 support 16 TB of maximumfilesystem size, and 2 TB of maximum file size. ext4 adds 48-bit blockaddressing, so it will have 1 EB of maximum filesystem size and 16 tbof maximum file size. 1 EB = 1,048,576 Tb (1 EB = 1024 Pb, 1 Pb = 1024 TB, 1TB = 1024 GB). Why 48-bit and not 64-bit? There are somelimitations that wowould need to be fixed before making ext4 fully failed, which have not been addressed in ext4.
