Delay In Storage Transactions


The fundamental physical limitation is the speed of light, which takes at least 16 milliseconds to cross the US coast-to-coast (that's in a vacuum - it takes at least four times BTW external drives are NOT designed for continuous duty. The only exception to this would be an enclosure that has its own cooling fan. However, "paged" bucket lists are not really "in-progress" in S3 - they are composed of separate, independent requests.

I just can't see any reason why anything could cause a multiple-second delay in an electronic storage medium, since electricity is fast, and there shouldn't be any delay longer than a Aha!

S3 Eventual Consistency Delay Or else opening a text file that I have saved. Read-after-write Consistency Wikipedia I did try the BIOS setting, and it made the drive not boot, so I switched it back.

US-Standard has servers on both the east and west coasts (remember, this is S3 not EC2) in the same logical "region". With this new functionality, we use a region of memory which is mapped to a file on a DAX volume to hold that buffer.

One of the most significant performance bottlenecks for low latency OLTP transactions is writing to the transaction log. But requires some updates. Does the SSD have a power saving mode where it goes on standby until it's used? Backup/Restore Backup/Restore operates normally.

After COMMIT, control is returned to the client before any ACK is received from any synchronous secondary. Otherwise, I would power it down when not needed...
