Hibernate Tip - How to use a timestamp for versioning and optimistic locking - Duration: 4:45.
Hi,
I'm Thorben Janssen from thoughts-on-java.org with a new Hibernate Tip.
When you had to map a legacy table model in one of your projects,
you probably know this situation.
Instead of a numeric version column,
the table model uses the timestamp of the last update.
I don't recommend using this approach
because numeric versioning is much more efficient.
But if you have to, you can also use a timestamp for versioning
with JPA and Hibernate.
The JPA specification supports numeric and timestamp columns for versioning.
You can use the timestamp column in the same way as a numeric version column.
You just need an entity attribute of type java.util.Date
and annotate it with Version annotation.
Let's take a quick look at an example before we talk
about the problems that this approach might introduce.
Here you can see a simple Author entity with a version attribute of type java.util.Date.
The attribute is annotated with Version
so that Hibernate knows that it has to update
its value with the current JVM timestamp
for each insert and update operation.
Let's run a quick test and take a look at the generated SQL statements.
Here you can see the INSERT statement.
Hibernate sets the value of the version column
to the current timestamp.
That was easy and it might seem like the timestamp
would be a good alternative to the numeric version column.
But please be aware that it has a few drawbacks.
The JVM usually doesn't provide the timestamp with millisecond accuracy.
And Hibernate can't detect 2 concurrent updates
that are executed at the same millisecond.
And If you scale your application horizontally,
you need to keep the timestamp of all instances in sync.
You can avoid 2 of the 3 drawbacks by retrieving the version timestamp from your database.
That is a Hibernate-specific feature that is not supported by all Hibernate Dialects
and requires an additional database query.
So, you shouldn't use it,
if you need to optimize your application for performance.
If you want to use this feature, you need to annotate your version attribute
with an additional Type annotation
and set its type attribute to dbtimestamp.
Here you can see the same Author entity as in the previous example.
I just added the Type annotation to tell Hibernate
to retrieve the timestamp from the database.
Let's see what happens when I now persist a new Author entity.
Hibernate performed an additional query to
retrieve the current time from the database
before it wrote the new record to the Author table.
That's obviously slower than the numeric versioning and
JPA's timestamp-based versioning approach.
But you don't need to keep the time of all application instances in sync
and you're not struggling with the insufficient timestamp accuracy of your JVM.
OK, that's it for today.
If you want to learn more about Hibernate,
you should join the free Thoughts on Java Library.
It gives you free access to a lot of member-only content like
an ebook about the Java 8 support in Hibernate,
a printable PDF version of this Hibernate Tip,
lots of cheat sheets and a video course.
I'll add the link to it to the video description below.

WAYS TO CUSTOMIZE ILLUSTRATOR FOR GRAPHIC DESIGN | Satori Graphics - Duration: 5:41.
today I'm going to show you four ways to customize illustrator for graphic design
and how to pimp your software move to the time stamp in the corner if you wish
to skip the intro
what is up people welcome back to Satori graphics the home of graphic design
content right here on YouTube I'm thinking about starting a weekly series
why take designs from you guys I either critique them or give you advice on
these designs it could be a logo design it could be artwork it could be anything
at all if you think this is a good idea let me know in the comment section below
and if you want to send me your designs tag me on Twitter I'll check these
designs whenever I can now ways to customize illustrator for graphic design
the first way to customize illustrator is to change your workspace settings if
you go up to window in their workspace you'll find some presets right there so
for example I might be working on a typography design in Illustrator when I
clear the typography workspace settings he only shows tool panels that might be
relevant to typography design have a browser of the precess but I'm
gonna show you how to customize these personally for your grapple as I
workflow let's say I'm working on a logo design I would want the type window open
and maybe the Pathfinder window too if I want everything as it is now an
illustrator setup this way for every single local design project in
the future I can go up to window workspace and new workspace then type in
a relevant name and you have saved a new preset for your graphical design
projects
as you can see it's been saved here and if you want to delete the preset go up
to window workspace and manage workspaces
smart guides really help when you're using the pen tool for drawing out
intricate designs in Illustrator I will show you how to customize and activate
them but first you can see these pink or magenta lines showing up when I use the
pen tool and perfectly aligned the different point on my design if you come
over to illustrator preferences and they're smart guides this window will
appear here you can customize the color of your guides as well as what you want
the guides to connect to or nearly straight to designs if you want the guys
to operate at specific angles you can adjust I here and finally the tolerance
would dictate how sensitive the guides are
this way to customize illustrator for graphic design can be both handy and
annoying depending on what you're doing when I draw with the pen tool you may
notice a very small hex icon appear at the rate tip of the pen
and if I move my cursor will freeze in that place as if stuck by glue for a
specific moment this is because I have the snap to point
option activated which you can find here
this will again help with accuracy when drawing vector paths in Illustrator but
if you wanting to go totally freehand with the pen tool it can be annoying the
maximum tolerance you can use is eight for this setting
another way to customize illustrator for graphic design is one that has really
helped me in the past if you find that being on the computer all day long
working your graphic design can be strenuous on your eyes you can head over
to the user interface settings in the illustrator preferences and you can
customize the background color of Adobe Illustrator I prefer keeping your set to
a darker tone it's a lot easier on the eyes some might call this a night mode
setting to finish up in today's tutorial on ways to customize illustrator for
graphic design I have a bonus tip for you guys firstly if you want to remove
all panels from your screen for a brief moment simply press tab on your keyboard
this allows you to view your designs clearly secondly if you have many
windows and panels open you can merge them into one long line neatly at the
side
so did you find today's tutorial on ways to customize illustrator useful let me
know in the comment section below and subscribe to tutorial graphics for for
weekly crappy design uploads until next time diss on your future
today peace
