Flow Telemetry doesn't rely on global state, there are no singletons.
Yet it follows OTEL specification.
flow-php/telemetry-otlp-bridge helps with serialization telemetry objects to open telemetry protocol.

I'm working on new package for Flow #PHP Framework! 🤯
Two packages to be more precise:

Last week I moved flow-php.com from G💩💩le to @ProtonMail
Was planning this since a while but never had enough time, but let me tell you... It's AWESOME! User interface is light and clean, mobile apps works great. And those aliases <3

Need to extract filtered data from PostgreSQL with pagination?
Pass your WHERE parameters directly and Flow handles pagination correctly.
The extractor auto-detects your parameter positions. If you use $1, $2 for filters, pagination params start at $3.
#PHP #PostgreSQL #ETL

Flow #PHP now supports onComplete callbacks for Symfony streamed responses.
After streaming finishes, you get a Report with row counts, execution time, and memory stats.

Building SQL queries with optional filters is messy.
If-statements everywhere. String concatenation. Easy to mess up.
Flow PHP now has a fluent condition builder for PostgreSQL queries.
Build WHERE clauses incrementally. Add conditions when they exist, skip when they don't.

From time to time I'm getting a feedback that Flow #PHP DSL is "ugly".
I disagree! it's just different than what most devs are used to.
Flow DSL is based on underscore, lower case functions that under the hood are creating objects. Yes, Flow is object oriented!

Pagination is one the techniques to retrieve large data from database. Flow #PHP adapter for #PostgreSql provides 3 different types:
- limit offset
- key set
- cursor
Do you know which one is the least scalable?
- limit offset
- key set
- cursor

Data processing in #PHP is still in it's early stages. Don't believe me? Look at your system and tell me how it's handling imports/exports.
Is it perhaps hand written importer/exporter?
Any chance it's using file_get_contents?
What stops you from using a Data Frame?

flow-php/pg-query quickly escalated from "I just want to parse sql to AST" into "why not build a proper query builder?" 😅
So there is, #PHP Query Builder for #PostgreSQL inspired by JOOQ
(API will change, this is just PoC)

I just upgraded Flow #PHP Playground.
Now it opens preview of predefined/uploaded files in tabs.
I also added some colors to the output to make it more readable.

1/8 I have been recently playing with the idea of creating an interactive playground for Flow #PHP where the ETL pipeline can be executed directly in the browser.
Today I managed to put together the first working version!

Flow #PHP can now be run on Windows! But not through WSL, pure Windows. The main blocker was the flow-php/filesystem library. I managed to turn the Path class into a facade that detects the OS and uses dedicated Windows or Unix Path implementation under the hood.
