When you use window functions in SQL, you can't filter their results directly in a WHERE or HAVING clause — that's a well‑known limitation across many databases. GBase 8a, the China‑domestically developed MPP database from GBASE, solves this elegantly with the QUALIFY clause. Let's break down how it works, what it can do, and where you need to be careful. DROP TABLE IF EXISTS emp; CREATE TABLE emp
As data grows, you'll likely need to add nodes to your existing GBase 8a MPP cluster without downtime. This hands‑on guide walks through the full process of adding a composite GNode to a running GBASE cluster. Existing cluster: A healthy GBase 8a cluster New node: A server with a static IP address configured Network: All nodes must be able to communicate with each other Stop services on all existi
By default, identifiers in GBase 8s are case‑insensitive: uppercase letters are silently treated as lowercase. Setting the environment variable DELIMIDENT=Y changes how double‑quoted identifiers behave, enabling case‑sensitive table and column names. Here's a demonstration and a deep dive into the option, as used in a gbase database. With DELIMIDENT=y exported, execute the following statements: ex
Manifest V3 Is Here — And It Broke Everything Google's Manifest V3 migration deadline has come and gone. After migrating 17 Chrome extensions from MV2 to MV3, I've compiled every pitfall, workaround, and lesson learned. If you're still migrating — or building new extensions — this guide will save you weeks of debugging. The problem: MV3 replaces persistent background pages with service workers.
المشكلة لو بتكتب عربي وإنجليزي مع بعض في أي موقع، البراوزر بيتلخبط في الاتجاه: جملة زي "مرحبا API بتاعك كويس" — كلمة API بتتعكس وتتقرأ غلط بسبب الـ Unicode Bidi Algorithm. المشكلة دي مش في موقع معين — هي موجودة في كل المواقع. حتى Claude.ai وChatGPT نفسهم بيعانوا منها. بدل ما نضبط dir="rtl" على الـ element بس، عملت BiDi parser حقيقي يقسّم النص: "مرحبا API tools بتاعك" ↓ tokenizer [arabic]
This post walks through setting up a distributed Hadoop cluster from scratch and loading data from HDFS into GBase 8a, GBASE's China-domestically developed MPP database. The full pipeline covers environment prep, config tweaks, cluster verification, and the final load command. Create a hadoop user on all nodes and configure passwordless SSH. Add Java and Hadoop paths to ~/.bash_profile on every no
OPTOFC (optimize-OPEN-FETCH-CLOSE) is a JDBC option in GBASE's GBase 8s that reduces network round trips when executing SELECT statements with PreparedStatement. This post explains how it works and demonstrates the real performance gain with benchmarks. The optimization kicks in only when all of the following are true: The statement is a PreparedStatement instance. The query is a SELECT. The Re
