Data Storage

It turns out there's a handy feature in PostgreSQL called row constructor comparisons that allows me to compare tuples of columns. That's exactly what we need. Instead of doing CreateAt > ?1 OR (CreateAt = ?1 AND Id > ?2) , we can do ( CreateAt, Id) > (?1, ?2) . And the row constructor comparisons are lexicographical, meaning that it's... See more

Datasette is a tool for exploring and publishing data. It helps people take data of any shape, analyze and explore it, and publish it as an interactive website and accompanying API.

Datasette is aimed at data journalists, museum curators, archivists, local governments, scientists, researchers and anyone else who has data that they wish to share with... See more

Our Goals

We made it lightweight and kept the efficiency in mind:

• Self-contained
  
  We ship a single dependency-free binary that runs on all Linux distributions


• Fast to deploy, safe to operate
  
  We are sysadmins, we know the value of operator-friendly software


• Deploy everywhere on every machine
  
  We do not have a dedicated backbone, and neither do you,
  
  so

For High Throughput data, Grab uses Apache Avro with a strategy called Merge on Read (MOR) .

Here's the main operations with Merge on Read:

• Write Operations - When data is written, it's appended to the end of a log file. This is much more efficient than merging it in the current data and reduces the latency of writes.


• Read Operations - When you need

Unlike some other popular algorithms, DiskANN is designed to keep memory usage to a minimum. This makes it a great match for use cases where Turso already excels at.

#Multitenancy

Turso allows for an easy implementation of a database-per-tenant pattern, where databases can be cheaply created on-demand. Keeping memory consumption at bay is critical... See more

7 must-know strategies to scale your database

Indexing:

Check the query patterns of your application and create the right indexes.

Materialized Views:

Pre-compute complex query results and store them for faster access.

Denormalization:

Reduce complex joins to improve query performance.

Vertical Scaling

Boost your database server by adding more CPU, RAM, or... See more

For low throughput data, Grab uses Parquet with Copy on Write (CoW) .

Here's the main operations for Copy on Write:

• Write Operations - Whenever there's a write, you create a new version of the file that includes the latest change. You can also keep the previous version for consistency and rollback purposes. This helps prevent data corruption,
