This means data can be stored in file system cache, non-stable media. ) The issue, as described in the link, is that the sync returns the error but may clear the state of the cached pages. The next sync returns ESUCCESS, meaning the the write(s), which were in cache, do not flush to stable media but applications were told they did.

In industry, engineers (me included) sometimes attack a problem with the tools they have readily available rather than taking a step back and examining the issue at large. Hardware engineers design and implement solutions in RTL, while software engineers attempt to solve the problem either at the OS or application level.

FILE cache type was the default leading to incorrect principal errors. The klist utility is helpful to show things like the currently cached Kerberos information. Ticket cache: KEYRING:persistent:0:0. Kerberos Cache = KEYRING. Make sure your Kerberos cache is KEYRING (DIR works as well) and not FILE or MEMORY.

If you study a CPU you will find various cache levels (L1, L2, …) In fact, the further away from the CPU the colder the memory is considered. Having the memory the instructions need in CPU cache allows for faster response. Having to load data from remote memory locations or secondary cache lines is considered COLD (takes longer.).

Their result is particularly promising for specialized index structures termed as learned indexes which has potential to replace B-Trees without major re-engineering. They demonstrated that neural nets based learned index outperforms cache-optimized B-Tree index by up to 70% in speed while saving an order-of-magnitude in memory.
