ndb Models are not saved in memcache when using MapReduce

由 蓝咒 提交于 2019-12-06 12:39:14
I've created two MapReduce Pipelines for uploading CSVs files to create Categories and Products in bulk. Each product is gets tied to a Category through a KeyProperty. The Category and Product models are built on ndb.Model, so based on the documentation, I would think they'd be automatically cached in Memcache when retrieved from the Datastore. I've run these scripts on the server to upload 30 categories and, afterward, 3000 products. All the data appears in the Datastore as expected. However, it doesn't seem like the Product upload is using Memcache to get the Categories. When I check the

Help with PHP call_user_func and integrate function into Class?

由 北城以北 提交于 2019-12-06 12:13:25
问题 Below is a function I found about a year ago that is supposed to put a lock on a memcache key so you can update it's value without any trouble of 2 request trying to update the key at the same time. It is pretty basic but I could use a little help in figuring out how to use it 100%. The part I am not sure about is where it passes in a $updateFunction which is then passed to ** call_user_func($updateFunction, $data); // update data I have never used the call_user_func() before. Based on this

C# architecture advice: method to cache data in a structure?

由 时光怂恿深爱的人放手 提交于 2019-12-06 12:10:56
问题 I'd like to ask your expert advice on a workable architecture in C#. I have a C# service which responds to a request from a local user on the LAN, fetches packets of data from the internet, and crunches that data to produce arrays of data in a structure. Each data request takes about 2 seconds, and returns 4000 bytes. There could be tens of thousands of requests per day. To speed everything up, and reduce bandwidth, I need to cache the results of the data crunching so that 2nd and subsequent

Memcache - storing mysql results

由 心不动则不痛 提交于 2019-12-06 12:07:25
问题 I have a database class, which manages all my mysql connections for my application. I'm having to (belatedly) implement Memcache, for a number of reasons. I've started to figure it out but want to confirm one thing. I was hoping to make amendments to class with defaults on timeout. It sees if it's in memcache, if not - make the query and store it. However, it appears as though you can't store mysqli results (via this question). Does that mean you can't use any code in the application which

Migrating Memcached client from Memcached-Java-Client to Xmemcached

由 ε祈祈猫儿з 提交于 2019-12-06 10:18:52
I have an old memcached client implementation that is based of the danga client, but was slightly modified. I think this client is now called Memcached-Java-Client . The implementation I have at hand is old, unmaintained, and seem to be bogus. I need to migrate the client to a newer client with the following constraints: I need the new client hashing algorithm to be compatible with the old one. If this constraint is not met, we will have to make the site (at least partially) unavailable for a few hours. Support various serialization methods, and allow extensibility for the serialization method

memcached - using with a C# asp.net application

问题 I'm considering using memcached (at some point) in my application i'm currently developing. Eventually, i'm planning on hosting this on Amazon EC2 - i was just wondering, would it be possible to have a linux server (aws instance) running memcached, and use the windows server (aws instance) for the app, but set it to use the linux server for the cache?? 回答1: Definitely possible. I suggest using the enyim.com client instead of the "official one" as it a lot faster. 回答2: You can access the

Idiots guide to app engine and memcache

由 ≡放荡痞女 提交于 2019-12-06 07:13:40
I am struggling to find a good tutorial or best practices document for the use of memcache in app engine. I'm pretty happy with it on the level presented in the docs. Get an object by ID, checking memcache first, but I'm unclear on things like: If you cache a query, is there an accepted method for ensuring that the cache is cleared/updated when an object stored in that query is updated. What are the effects of using ReferenceProperties ? If a cache a Foo object with a Bar reference. Is my foo.bar in memcache too and in need of clearing down if it gets updated from some other part of my
