Second, pagination is generally a function of the front-end and/or middleware, not the database layer.
But some database languages provide helpful facilities that aide in implementing pagination. For example, many SQL dialects provide LIMIT and OFFSET clauses that can be used to emit up to n rows starting at a given row number. I.e., a “page” of rows. If the query results are sorted via ORDER BY and are generally unchanged between successive invocations, then that can be used to implement pagination.
That may not be the most efficient or effective implementation, though.
So how do you propose pagination should be done?
On context of web apps , let’s say there are 100 mn users. One cannot dump all the users in response.
Cache database query results in the middleware layer using Redis or similar and serve out pages of rows from that.
What if you have 30, 000 rows plus, do you fetch all of that from the database and cache in Redis?
I feel the most efficient solution is still offset and limit. It doesn’t make sense to use a database and then end up putting all of your data in Redis especially data that changes a lot. Redis is not for storing all of your data.
If you have large data set, you should use offset and limit, getting only what is needed from the database into main memory (and maybe caching those in Redis) at any point in time is very efficient.
With 30,000 rows in a table, if offset/limit is the only viable or appropriate restriction, then that’s sometimes the way to go.
More often, there’s a much better way of restricting 30,000 rows via some search criteria that significantly reduces the displayed volume of rows — ideally to a single page or a few pages (which are appropriate to cache in Redis.)
It’s unlikely (though it does happen) that users really want to casually browse 30,000 rows, page by page. More often, they want this one record, or these small number of records.

But when such ‘paginated’ queries are called back to back, does the database engine actually do the entire ‘select’ all over again and then retrieve a different subset of results each time? Or does it do the overall fetching of results only once, keeps the results in memory or something, and then serves subsets of results from it for subsequent queries based on offset and size?
If it does the full fetch every time, then it seems quite inefficient.
If it does full fetch only once, it must be ‘storing’ the query somewhere somehow, so that the next time that query comes in, it knows that it has already fetched all the data and just needs to extract next page from it. In that case, how will the database engine handle multiple threads? Two threads executing the same query?
something will be quick or slow without taking measurements, and complicate the code in advance to download 12 pages at once and cache them because “it seems to me that it will be faster”.
Answer: First of all, do not make assumptions in advance whether something will be quick or slow without taking measurements, and complicate the code in advance to download 12 pages at once and cache them because “it seems to me that it will be faster”.
YAGNI principle – the programmer should not add functionality until deemed necessary. Do it in the simplest way (ordinary pagination of one page), measure how it works on production, if it is slow, then try a different method, if the speed is satisfactory, leave it as it is.
From my own practice – an application that retrieves data from a table containing about 80,000 records, the main table is joined with 4-5 additional lookup tables, the whole query is paginated, about 25-30 records per page, about 2500-3000 pages in total. Database is Oracle 12c, there are indexes on a few columns, queries are generated by Hibernate. Measurements on production system at the server side show that an average time (median – 50% percentile) of retrieving one page is about 300 ms. 95% percentile is less than 800 ms – this means that 95% of requests for retrieving a single page is less that 800ms, when we add a transfer time from the server to the user and a rendering time of about 0.5-1 seconds, the total time is less than 2 seconds. That’s enough, users are happy.
And some theory – see this answer to know what is purpose of Pagination pattern

Hello everyone, I am currently enrolled in a Database Management Systems course at my university, and there is a group project. There are no guidelines from the prof or the TAs on how to implement the project - We have only been learning theory in class.

Any tips on what we should do to get the project going would be great. Thank you. submitted by /u/Federal_Carry [link] [comments]
I’m working on an article with a tentative title of “Tales of the Crypt: Horror stories where database performance caused a real problem.” It’s meant to be schadenfreude nostalgia, about your late nights coping with a performance issue (with, hopefully, a happy ending of “…and this is what we did to fix it”). So, what happened? Tell me about it. (And you know everyone here wants to hear the story too.) I want to quote you, but we can be oblique about the attribution – especially because sometimes these stories are from a previous employer and do not represent any current affiliation. But I do want the verisimilitude that demonstrates that these tales-of-woe come from real people. As a result, I’m fine with writing, “Kim’s first job was as a mainframe programmer at a hotel chain, where database transactions required tape changes. ‘Yada yada story,’ says Kim, who now is CIO of a Midwest insurance firm.” Real person, but you don’t need to worry about getting anyone to approve your words. (Though if you’re happy with full name, company, and role, I’m even happier; send in a private message if you prefer.) I used an ancient example above, but I’m hoping for more recent database performance stories. Ideally some of the “here’s how we fixed it” become practical suggestions for developers who are enduring such a situation today. submitted by /u/yourbasicgeek [link] [comments]

I'm developing a library (ORM for node.js TS) and looking for a way to allow users to switch databases in the documentation. So if the user chooses Postgres, docs will show pages with Postgres-specific features, and specific column types. If the user chooses another db, it still shows common features but can show a different set of column types and different db-specific features. I'm looking for an example of if it's already done in some other library or tool, to maybe took inspiration from. But the libraries I know either specialize on a single db, or tries to give you a generic interface as if there is no big difference between dbs, or they support multiple documents for different dbs even though most of the content stays the same. So if you know such docs with switching (any programming language, any tool) please share. submitted by /u/romeeres [link] [comments]

Let me explain the table definition first CREATE TABLE IF NOT EXISTS `words` ( `id` INT UNSIGNED NOT NULL AUTO_INCREMENT, `word` VARCHAR(255), `word_data` JSON NULL, `created_at` DATETIME NULL, `updated_at` DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP, PRIMARY KEY `pk_id`(`id`), CONSTRAINT words_word_unique UNIQUE (word) ) ENGINE = InnoDB; Basically it should prevent the duplicate value on the word column. And the query I am running to insert into the table "Insert ignore into words(word,created_at) values(?,now());" Now, the problem is there is duplicate word after I insert 252 rows successfully. So, when the query goes to the following unique word, instead of making a new row at id 253; it starts at id 254. The console output at that point: last inserted id 251 rows affected 1 last inserted id 252 rows affected 1 last inserted id 0 rows affected 0 last inserted id 254 rows affected 1 last inserted id 255 rows affected 1 I have also tried with the query "Insert into words(word,created_at) values(?,now()) on duplicate update updated_at=now(); " It also gives the same result. So, what I am doing wrong? I tried to find the reason on the internet, but could not. Hence I am posting it here. I am using SqlX golang package for query execution. submitted by /u/xatta_trone [link] [comments]

Tags: #AmazonLex, #CogintiveServices, #AzureSpeech, #Api.ai, #DialogFlow, #Tensorflow Differences: api.ai provides us with such a platform which is easy to learn and comprehensive to develop conversation actions. It is a good example of the simplistic approach to solving complex man to machine communication problem using natural language processing in proximity to machine learning. Api.ai supports context based conversations now, which reduces the overhead of handling user context in session parameters. On the other hand in Lex this has to be handled in session. Also, api.ai can be used for both voice and text based conversations (assistant actions can be easily created using api.ai).

Data orchestration, ETL, Analytics and visualization References: [AWS]:EMR, Data Pipeline, Kinesis Stream, Kinesis Firehose, Glue, QuickSight, Athena, CloudSearch [Azure]:Azure Databricks, Data Catalog Cortana Intelligence, HDInsight, Power BI, Azure Datafactory, Azure Search, Azure Data Lake Anlytics, Stream Analytics, Azure Machine Learning [Google]:Cloud DataProc, Machine Learning, Cloud Datalab Tags:#EMR, #DataPipeline, #Kinesis, #Cortana, AzureDatafactory, #AzureDataAnlytics, #CloudDataProc, #MachineLearning, #CloudDatalab Differences: All three providers offer similar building blocks; data processing, data orchestration, streaming analytics, machine learning and visualisations. AWS certainly has all the bases covered with a solid set of products that will meet most needs. Azure offers a comprehensive and impressive suite of managed analytical products. They support open source big data solutions alongside new serverless analytical products such as Data Lake. Google provide their own twist to cloud analytics with their range of services. With Dataproc and Dataflow, Google have a strong core to their proposition. Tensorflow has been getting a lot of attention recently and there will be many who will be keen to see Machine Learning come out of preview.
Category: Serverless Description: Integrate systems and run backend processes in response to events or schedules without provisioning or managing servers. References: [AWS]:AWS Lambda [Azure]:Azure Functions [Google]:Google Cloud Functions Tags:#AWSLAmbda, #AzureFunctions, #GoogleCloudFunctions Differences: Both AWS Lambda and Microsoft Azure Functions and Google Cloud Functions offer dynamic, configurable triggers that you can use to invoke your functions on their platforms. AWS Lambda, Azure and Google Cloud Functions support Node.js, Python, and C#. The beauty of serverless development is that, with minor changes, the code you write for one service should be portable to another with little effort – simply modify some interfaces, handle any input/output transforms, and an AWS Lambda Node.JS function is indistinguishable from a Microsoft Azure Node.js Function. AWS Lambda provides further support for Python and Java, while Azure Functions provides support for F# and PHP. AWS Lambda is built from the AMI, which runs on Linux, while Microsoft Azure Functions run in a Windows environment. AWS Lambda uses the AWS Machine architecture to reduce the scope of containerization, letting you spin up and tear down individual pieces of functionality in your application at will.
Category:Caching Description:An in-memory–based, distributed caching service that provides a high-performance store typically used to offload non transactional work from a database. References: [AWS]:AWS ElastiCache (works as an in-memory data store and cache to support the most demanding applications requiring sub-millisecond response times.) [Azure]:Azure Cache for Redis (based on the popular software Redis. It is typically used as a cache to improve the performance and scalability of systems that rely heavily on backend data-stores.) [Google]:Memcache (In-memory key-value store, originally intended for caching) Tags:#Redis, #Memcached <Differences: They all support horizontal scaling via sharding.They all improve the performance of web applications by allowing you to retrive information from fast, in-memory caches, instead of relying on slower disk-based databases.”, “Differences”: “ElastiCache supports Memcached and Redis. Memcached Cloud provides various data persistence options as well as remote backups for disaster recovery purposes. Redis offers persistence to disk, Memcache does not. This can be very helpful if you cache lots of data, since you remove the slowness around having a fully cold cache. Redis also offers several extra data structures that Memcache doesn’t— Lists, Sets, Sorted Sets, etc. Memcache only has Key/Value pairs. Memcache is multi-threaded. Redis is single-threaded and event driven. Redis is very fast, but it’ll never be multi-threaded. At hight scale, you can squeeze more connections and transactions out of Memcache. Memcache tends to be more memory efficient. This can make a big difference around the magnitude of 10s of millions or 100s of millions of keys. ElastiCache supports Memcached and Redis.

Azure Stack is a hybrid cloud platform that enables you to run Azure services in your company’s or service provider’s datacenter. As a developer, you can build apps on Azure Stack. You can then deploy them to either Azure Stack or Azure, or you can build truly hybrid apps that take advantage of connectivity between an Azure Stack cloud and Azure.
Basically, it all comes down to what your organizational needs are and if there’s a particular area that’s especially important to your business (ex. serverless, or integration with Microsoft applications).
Some of the main things it comes down to is compute options, pricing, and purchasing options.
Here’s a brief comparison of the compute option features across cloud providers:
Here’s an example of a few instances’ costs (all are Linux OS):
Each provider offers a variety of options to lower costs from the listed On-Demand prices. These can fall under reservations, spot and preemptible instances and contracts.
Both AWS and Azure offer a way for customers to purchase compute capacity in advance in exchange for a discount: AWS Reserved Instances and Azure Reserved Virtual Machine Instances. There are a few interesting variations between the instances across the cloud providers which could affect which is more appealing to a business.
Another discounting mechanism is the idea of spot instances in AWS and low-priority VMs in Azure. These options allow users to purchase unused capacity for a steep discount.
With AWS and Azure, enterprise contracts are available. These are typically aimed at enterprise customers, and encourage large companies to commit to specific levels of usage and spend in exchange for an across-the-board discount – for example, AWS EDPs and Azure Enterprise Agreements.
