Best way to query - filters vs. get() cache?

Hello

I'm in a dillemma. Whether to use the methods NamedCache.get () or entrySet (filter) to query the cache. Please guide me...

My understanding is that when using

1. get() or getAll(), consistency checks if the entry is in the cache, if it does not exist in the cache, coherence get his from the data store
2. simply entrySet (Filters), consistency checks the cache, and returns the results based on what is available in the cache.

In this case, is it not better to use get instead entrySet in a case where we do not know if up-to-date data are available in the Cache?

1. What is the difference between using a get and entrySet ?
2. How do we make sure that up-to-date data are available in the cache when the use not a writeback scenario?

I'm newbie... Gurus, please guide me...

Thank you, Robert.

So the air if I the search parameter is identical to the key, then its better to use get or count with all

Currently, I have a set of expiry-delay of 1 min on the Cache. So, this extract the expired data from the data store. Are there any trigger to get out of the box of coherence mechanisms?

I'm not sure that what you call the extraction of trigger mechanism.

Consistency can make periodic updates cached entries that have recently been consulted within a configurable time thanks to its cooling function in advance. You can read about it at http://wiki.tangosol.com/display/COH35UG/Read-Through%2C+Write-Through%2C+Write-Behind+and+Refresh-Ahead+Caching#Read-Through%2CWrite-Through%2CWrite-BehindandRefresh-AheadCaching-RefreshAheadCache

If this is not what you're after, would you care to elaborate a little bit on what you need?

Best regards

  • Best way to present a query recordset to a remote server

    Hello, everyone.

    I was responsible for a project that will involve querying a table on a server, then send the data to a remote server that will take the data and insert it into another database (the two db cannot communicate directly with each other).

    I've never had to do something like that before.  What is the best way to get the desired results?  Is it possible to "petition" (anywhere from 1 to 5 files at a time) to the remote server without incorporating WDDX?

    Hi, @BKBK,

    Not allowed.

    This is the kind of tedious, but I've worked so far is having CF1 select data from DB1, SerializeJSON data, cfhttp allows to VALIDATE data for CF2.

    THEN, CF2 DeserializeJSON data in a query object and that insert into DB2.

    Unless you think there is a better way to do it?

  • What is the best/best way to get just Photoshop and first applications?

    Hello Adobe community.

    I'm curious the best about the ideal way to get just Photoshop and first. I have currently the library full of Adobe applications, and I noticed that I don't use the majority of the applications outside of these two. My subscription of the year ends in November (thank you for Black Friday deals). I want an idea of some of the things that I can do to save money and get the best value for both applications as the price of subscriptions is a little strange.

    After watching the price of subscriptions and their descriptions, is logical that the best option I have is to get the Plan of Single-App creative cloud for first ($19.99 per month) and also opt it for the Photoshop & Lightroom Plan ($ 9.99 per month)?

    The price, I was looking at: plans membership: pricing and subscriptions | Adobe Creative Cloud

    I appreciate any help I can get. See you soon!

    If you want these two programs (Lightroom does bundle special photographer, but there is of course no need to install or use) then what you described is the only way

    Don't forget to cancel your existing subscription before the end of your current period

    Find it me easier to add online and I think this is the best way. This way I have add a container then an ID and this is where I add questions from the media. Is this the wrong way? I keep seeing people adding them in the CSS file. What is the best and why? I'm a newb. Thank you!

    I think that sometimes people get a little confused by the Bootstrap classes that establish points of breaking for you if used correctly.  So in that sense, I guess that some people may think it's the CSS inline code.  But technically, it's just the HTML markup.   In this example, you can set widths different collar for xs, sm, md and lg devices.   Bootstrap is mobile in the first place, so the default value is 12-xs-col.  This is why we don't need to express it in our code.

  • What is the best way to get a customized version # from an ESXi host?

    Each quarter, we generate a sequence of updates (including patches and security scripts) which are performed manually on our 5.0 ESXi hosts. I don't have an internet connection and so I have to do it this way.  I would like to be able to identify the last quarterly update that has been run on the vCenter servers and/or Client VI.

    Right now, I think adding the quarter, example 1 Q 13 on the DCUI message, then help PowerCLI, vCenter to retrieve the message DCUI, crawled and paste the quarter in the field host Annotations on vCenter.

    Kind of ugly, but I cannot find a cool way to get data like this outside of the host.  I don't want to rely on my user manually set to nothing, for example the field of Annotations on vCenter that is also subject to errors.

    I really want something that can also be seen on the VI Client, too, as the annotations are only on vCenter.

    I have ideas about the best approach to tackle this problem.

    Thank you

    Not sure if this is the best way, but that's what I ended up doing.   It feels like there should be a better way.

    I've updated my quarterly script to add the version number at the bottom of the file, / etc/vmware/welcome, whenever it is run on an ESXi host (e.g. myScript version: v1.0 Date: 04June2013).  This file appears under the banner DCUI.

    Then, I wrote a script powerCLI to roughly the following:

    foreach ($vmHostObj in Get-VMHost-name *) {}

    # Get the full message of DCUI in/etc/vmware/welcome

    $msgObj = echo $vmHostObj | Get-VMHostAdvancedConfiguration-name Annotations.WelcomeMessage

    # Convert a hash of a string table welcome message

    $msgTxt = echo $msgObj.Item ("Annotations.WelcomeMessage")

    # find the clue for the string containing my script information, which is at the end of the welcome message.

    # This is important because the substring below function will extract everything after the index.

    $idx = $msgTxt.IndexOf ("version myScript :")

    If ($idx - gt 0) {}

    $label = $msgTxt.Substring ($idx)

    Set Annotation - remarks on the entity $vmHostObj - CustomAttribute - value $label

    }

    }

    This replaces the Notes field for each host, one day I can go back and make it more user-friendly where it replaces the version leaving the rest of the field notes intact.

  • What is the best way to optimize a SQL query: call a function or doing a join?

    Hi, I want to know what is the best way to optimize a SQL query, call a function inside the SELECT statement, or make a simple join?

    It depends on.  Could be a.  Could be the other.  Could be no difference.  You would need to compare with your tables in your environment with your settings.

    If you put a gun to my head, I was given no other information and required that I answered the question, I would tend to wait that the join would be more effective.  In general, if you can do something in pure SQL, it will be more effective than if you call PL/SQL.
