Project mention: Distributed SQL Essentials: Sharding and Partitioning in YugabyteDB | dev.to | 2021-11-21
The SST files store the key-value pairs for tables and indexes. Sharding is the right term here because each tablet is a database (based on RocksDB), with its own protection. This looks like the sharded databases we described above, except that they are not SQL databases but key-value document stores. They have all the required features for a reliable datastore, with transactions and strong consistency. However, they don’t have the burden of managing them as multiple databases because the SQL layer is above. Joins and secondary indexes are not processed at this level because this prevents cross-shard transactions.

MongoDB is a general purpose, document-based, distributed database built for modern application developers and for the cloud era. This example will show you how to connect to and use MongoDB as your backend for your Next.js app.
-
sqlitebrowser
Official home of the DB Browser for SQLite (DB4S) project. Previously known as "SQLite Database Browser" and "Database Browser for SQLite". Website at:
Project mention: Is there an app for Mac that can take a CSV or JSON and create a populated coredata database directly? | reddit.com/r/iOSProgramming | 2022-01-19I like DB Browser for SQLite. It's free.

MMKV
An efficient, small mobile key-value storage framework developed by WeChat. Works on Android, iOS, macOS, Windows, and POSIX.
This library aims to provide a fast & reliable solution for you data storage needs in react-native apps. It uses MMKV by Tencent under the hood on Android and iOS both that is used by their WeChat app(more than 1 Billion users). Unlike other storage solutions for React Native, this library lets you store any kind of data type, in any number of database instances, with or without encryption in a very fast and efficient way. Read about it on this blog post I wrote on dev.to

ArangoDB
🥑 ArangoDB is a native multi-model database with flexible data models for documents, graphs, and key-values. Build high performance applications using a convenient SQL-like query language or JavaScript extensions.
(1) Joins are a challenge to implement, particularly if CPU, network, and storage use matter. To get excellent results the database needs a query optimizer that can make a good guess of what query plan will be effective.
(2) There are many databases with other query languages that support joins, just a few are

OPS
OPS - Build and Run Open Source Unikernels. Quickly and easily build and deploy open source unikernels in tens of seconds. Deploy in any language to any cloud.
-
nebula
A distributed, fast open-source graph database featuring horizontal scalability and high availability (by vesoft-inc)
One option is NebulaGraph if your looking for low latency, scalability, and HA.

Project mention: I searched for 1.18 seeds so you don't have to | reddit.com/r/technicalminecraft | 2021-12-02
The CSV is sorted descending by mushroom by default. You can easily do postfiltering/other sorting using SQL, e.g. using https://github.com/duckdb/duckdb. For example:

Yes it's possible. I've used, for example, the better-sqlite3 library, which is written in C++, in an Electron app. React in the Renderer process would call Main process over IPC, then Main would use the Node bindings to whatever native Node module you're using.

Silicon
A high performance, middleware oriented C++14 http web framework please use matt-42/lithium instead

Project mention: Are there any fast alternatives to databases (for tabular data but without SQL)? | reddit.com/r/cpp | 2021-09-28
Probably the most popular ORM for modern C++ is https://github.com/fnc12/sqlite_orm. I've never used it personally. But if you configure SQLite to disable all the barriers and all synchronisation, I think you'll find it goes very, very quickly even with the ORM layer in between.

I just wrote something using https://github.com/SqliteModernCpp/sqlite_modern_cpp, which I chose after 10 minutes of searching around. Should I have used yours instead? How should I decide?
