How to consume any Database as a Stream for heavy data processing using JavaScript 🤯🔥

🧵/1

#javascript #nodejs #streams #sql #nosql #tutorial #dataprocessing #database #business #data #strategy #pipeline @nodejs

The secret for processing anything using JavaScript is to handle data on demand.

Imagine data you wanna migrate data from a SQL database to a NoSQL DB. You would need to apply some business rules, clean up fields, filter data and then output them to the final output.

/2

You might know that you can block the Node.js (and the data source you're consuming) if you handle too much data at once in memory

The best practice then is to limit results, send individual data to a stream pipeline, and then ask for more data until you've consumed it all.

What are the most common types of #NoSQL #databases?

* Document databases store data in documents similar to JSON objects. Each document contains pairs of fields and values. The values can be a variety of types including strings, numbers, booleans, arrays, or objects 1/n

* Key-value databases are a type of database where each item contains keys and values. A value can typically only be retrieved by referencing its key, so learning how to query for a specific key-value pair is typically simple 2/n

* Wide-column stores store data in tables, rows, and dynamic columns, wide-column stores are commonly used for storing IoT data and user profile data. Cassandra and HBase are two of the popular wide-column stores 3/n

What is NoSQL?
*NoSQL databases are non tabular, and store data differently than relational tables
*NoSQL databases come in a variety of types based on their data model
* The main types are document, key-value, wide-column, and graph #cloudcomputing #NoSQL 1/n

non-relational database provides a mechanism for storage and retrieval of data that is modeled in means other than the tabular relations used in relational databases 2/n

A common misconception is that NoSQL databases or non-relational databases don’t store relationship data well. NoSQL databases can store relationship data—they just store it differently than relational databases 3/n

Yesterday one of my colleagues asked me about how to boost MongoDB performance.
I explained to him, and now it's worth sharing:

Performance tuning for #MongoDB :

1. Create custom indexes for your queries.
see: docs.mongodb.com/manual/indexes/

Thread 👇

#javascript #Nodejs

2. If you use mongoose always use "lean", by default mongoose queries return an instance of Mongoose Document class, and these are much heavier than vanilla javascript objects.

#javascript #Database #MongoDB #NoSQL

3. Reuse connections (Connect once, use multiple times):

Don't connect and disconnect DB every time you query something. You should connect once,
at the beginning of your app.

Setting up a new TCP Connection is expensive time-wise, memory, and network wise.

(1/12) ¿Cuál es el mejor stack tecnológico para un aplicación?

🅰️ Angular/Ionic = Frontend
🏗️ NestJS/GraphQL = API
💾 Couchbase = DB
🔃 Celery = Colas de tareas
☁️ Docker = Orquestador de servicios.

En este hilo explicó las razones👇

(2/12) 🅰️ #Angular posee características increíbles y es un Framework que permite tener una arquitectura sólida desde el inicio con código limpio.

(3/12) 📲 #Ionic y su ecosistema permite enfocarse en entregar valor y tener una UI/UX consistente para cualquier dispositivo, además que con capacitor se puede crear apps para Android/IOS/PWA/Electron.

.@alexbdebrie has another excellent post that details the benefits and downsides of using a Single-Table design with @DynamoDB. While I completely agree with him on the “benefits”, I have some thoughts on his “downsides” that I’d like to address. 🧵 alexdebrie.com/posts/dynamodb…

Downside #1: “The steep learning curve to understand single-table design”

There is no doubt that “thinking in #NoSQL” is a complete departure from traditional #RDBMS, but understanding how to correctly denormalize data is applicable to both single- AND multi-table designs.

If you are using a multi-table design in @DynamoDB that implements 3NF, then just STOP! Seriously, this is *beyond* wrong (I think presidents have been impeached for this). This is not what #NoSQL was designed for and you will get ZERO benefit from doing this. Spin up an RDBMS.

Jeremy Daly @ AWS re:Invent

@jeremy_daly

Kicked off @AWSreInvent 2019 by attending @houlihan_rick’s @DynamoDB modeling session. As expected, it was a 60 minute firehose of #NoSQL knowledge bombs. There was *A LOT* to take away from this, but here are some really interesting lessons that stuck out to me. #reInvent

DynamoDB performance gets BETTER with scale. Yup, you read that correctly, the busier it gets, the faster it gets. This is because, eventually, every event router in the fleet caches your information and doesn’t need to look up where your storage nodes are.

Big documents are a bad idea! It’s better to split data into multiple items that (if possible) are less than 1 WCU. This will be a lot cheaper and cost you less to read and write items. You can join the data with a single query on the partition key.

Over the last months, we improved our @OVHcloud Public Cloud ecosystem with our vision + your requests and feedbacks.
Fasten your seatbelt, here is a recap ! 🔽

Reminder: Public Cloud = bricks like compute, storage, network, PaaS, services,... sharing some concepts like pay-what-you-consume-only, usually mgmt by project, API everywhere and sharing physical hosts between multiple customers. But your VMs (called instances) are for you only

Let's start with compute. We now provide IOPS instances with high-perf SSD #NVMe disks.
#ELK, #Hadoop, #NoSQL ? Perfect uses-cases for them :) Trust me they "dechire grave" as we say here.
FIO benchmarks vs competitors = specifc thread soon :)

بمناسبة اليوم الوطني راح أهديكم سلسلة تغريدات ألخص فيها تجربتي مع منصة #فايربيس @Firebase
فايربيس هي منصة للمبرمجين وخصوصا مطوري التطبيقات تملكها قوقل @Google وهذا رابط المنصة firebase.google.com

لماذا فايربيس؟ فايربيس عبارة عن منصة باكاند backend متكاملة توفر لمطوري التطبيقات عدة خدمات على رأسها ١) ادارة المستخدمين firebase authentication و ٢) قاعدة بيانات #فايرستور #Firestore و ٣) تحليلات فايربيس اناليتكس firebase analytics لتحليل سلوك مستخدمي التطبيق

ايش يفرق فايربيس عن خدمات أخرى مثل قوقل كلاود او أمازون كلاود او غيرها؟
الفرق الرئيسي والأساسي هو انك تحصل على الباكاند من فايربيس كخدمة backend as a service او #BaaS بدون ما تكتب ولا سطر كود خارج تطبيقك. هذا لا يعني انك راح تستغني بشكل كامل عن كتابة كود باكاند زي ما راح نشوف

I've been spending a lot of time lately with @dynamodb in my #serverless applications, so I thought I'd share my surefire guide to migrating to it from #RDBMS. So here is…

How to switch from RDBMS to #DynamoDB in *20* easy steps… (a thread)

STEP 1: Accept the fact that Amazon.com can fit 90% of their retail site/system’s workloads into DynamoDB, so you probably can too. 🤔

STEP 2: Create an Entity-Relationship Model, just like you would if you were designing a traditional relational database. 👩‍💻

Bir yazılım geliştiricinin bilmesi gerekenlerle ilgili 15 maddelik flood geliyor.. Mümkün olduğunca fazla keywordü bir araya toplamaya çalıştım.
Hadi Başlıyoruz!

#Developer #Software #Java #code #kod #yazılım #development #computer #bilgisayar #tool #PC #IT #web #tech #data

1-Temel veri yapıları (linkedList, map, tree vb) ve temel algoritmalar (sıralama, arama vb)

Sıfırdan kodlama ihtiyacınız büyük ihtimalle hiç olmayacak. Ancak ihtiyaç anında doğru yerde doğrusunu seçebilmek için o veri yapısının veya algoritmanın nasıl çalıştığını bilmeniz şart

2- Network Temelleri

OSI Modelini ve 7 katmanı; temel protokolleri(#TCP-IP, TCP-UDP, #HTTP, #FTP), güvenlik protokollerini(#HTTPS, #SFTP, #SSL), monitoring protokolleri(#SNMP, ICMP) bilmekte fayda var. Ayrıca ağ ekipmanlarının görevlerini tanımak ve 7Layer yerlerini bilmek lazım
