amazon web services - What is the AWS DynamoDB Durability SLA? -


given s3 99.999999999% durability [1], equivalent figure dynamodb?

[1] http://aws.amazon.com/s3/

this question implies incorrect. though s3 has sla (aws.amazon.com/s3-sla) sla references availability (99.9%) has no reference durability, or loss of objects in s3.

the 99.999999999% durability figure comes amazon's estimate of s3 designed achieve , there no related sla.

note amazon s3 designed 99.99% availability sla kicks in @ 99.9%.

there no current dynamodb sla amazon, nor aware of published figures amazon on expected or designed durability of data in dynamodb. suspect less s3 given nature, relative complexities, , goals of 2 systems (i.e., s3 designed store data objects very, safely; dynamodb designed provide super-fast reads , writes in scalable distributed database while trying keep data safe).

amazon talks customers backing dynamodb s3 using mapreduce. customers dynamodb using redshift, has dynamodb compatibility built in. additionally recommend backing off-aws store remove single point of failure aws account.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
