It is a good feeling when you can unlock performance gains with some simple changes. Memgraph performance was already great, but keeps getting better.

🌘 使用圖形資料庫打擊犯罪：Memgraph 如何繪製與分析犯罪網路
➤ 圖形資料庫如何應用於打擊犯罪
✤ https://memgraph.com/blog/graph-databases-crime-fighting-memgraph-criminal-networks
圖形資料庫（如Memgraph）在犯罪打擊和情報工作中非常有效，因為它們擅長揭示和分析實體之間的關係，如個人、溝通渠道和地點。圖形資料庫在解決複雜犯罪組織網絡的映射和分析上發揮著重要作用，尤其在反恐和反情報行動中。這篇博客探討圖形資料庫在犯罪打擊中的應用，以及Memgraph的功能如何使其成為繪製和分析這些複雜網絡的理想工具。
+ 這篇文章很清晰地講解了圖形資料庫在犯罪打擊中的應用，很有啟發性。
+ Memgraph的即時數據處理和高效率並行查詢功能，為打擊犯罪提供了實用工具，值得廣泛應用在執法領域中。

Anyone here have experience with the #memgraph GQLAlchemy builder system and knows how one might pass significant amounts of constraint information (i.e. match a few hundred nodes by unique ID) into them?

I am glancing around at some fun data query stuff, but if I can't pass constrained subsets of the graphs around between query modules, it's all kind of a wash.

#memgraph the company I work for has a senior C++ opening. If it is a good fit for you or someone you know, I'd love to see yours or your friend's application.

I don't often post about work, but its worth sharing and celebrating from time to time.

A small team, including myself, have worked for a while to improve replication and introduce high availability to #memgraph

It is now at a stage which is developer ready. There maybe some future small changes to be done around UX but the majority of the work is done.

🥳 A big milestone 🚀

Kùzu is another open source property graph database management system with support of Cypher query language just like #neo4j and #memgraph (and Oracle with PGQL): https://kuzudb.com/

Really enjoyed working through this tutorial that gets Memgraph running locally and explores queries on a map of Berlin's subway.

Asks real questions that tell meaningful things about the syntax and environment.

I'm proud of my #memgraph changes today. Fixing some small #cpp #cplusplus issues. Now a simple query just got ~80% faster.

🌘 內存與磁盤數據庫：為什麼需要大於內存的架構？
➤ Memgraph的內存與磁盤數據庫
✤ https://memgraph.com/blog/in-memory-vs-disk-based-databases-larger-than-memory-architecture
Memgraph是一個內存圖形數據庫，最近增加了支持處理無法放入內存的數據的功能。然而，將主內存數據庫擴展到支持磁盤存儲是一個複雜的工程。大於內存的架構描述了一種數據庫架構，其中大多數計算仍然在主內存中進行，但數據庫也提供了在磁盤上存儲大量數據的能力。 Memgraph使用RocksDB作為擴展內存數據庫功能的鍵值存儲。在添加基於磁盤的數據存儲之前，我們的主要要求之一是不破壞基於主內存的存儲的性能。
+ Memgraph是一個非常有用的數據庫，可以處理大量數據，並且具有良好的性能。
+ 這篇文章很好地解釋了內存與磁盤數據庫之間的區別，以及為什麼需要大於內存的架構。
