diskless system network storage

As the number of users continues to rise, I have implemented scalable and highly reliable cluster deployment (lvs + keepalived) for applications with high access volumes ), however, some users still report slow access. The root cause of the problem is shared storage server NFS. In my network environment, N servers share the storage space of one server through nfs

transaction's version number).　　This ensures that the data is present either before the transaction starts, or when the transaction is created, or when the data is changed. 2. The deleted version number of this row of data must be undefined or larger than the transaction version number. This ensures that this row of data is not deleted until the transaction is started.So. The InnoDB is used for applications where data integrity/write performance requirements are high. MyISAM is suitable for que

. For a memory-based computing framework like SPARK, the GC problem is particularly prominent, it will cache a large amount of data in the JVM heap space, which is the data to be used in the calculation, the GC can not be removed, every time the full GC will do a global scan of the data, This is time consuming, and as the computational time increases and the heap memory data grows, the cost of the GC becomes larger.What is the solution? We first analyze what the root cause of this problem is, an
