PostgreSQL is the first relational database which recognized the need of non-atomic data types to support developers of applications from science to Web. Jsonb in Postgres is the attractive feature for modern application developers, who want to work with json documents without sacrificing a strong consistency and ability to use all the power of proven relational technology. Finally, SQL world has recognized the NoSQL and released the new SQL-2016 standard, which includes specification of...

A Deep Dive into PostgreSQL Indexing

Indexes are a basic feature of relational databases, and PostgreSQL offers a rich collection of options to developers and designers. To take advantage of these fully, users need to understand the basic concept of indexes, to be able to compare the different index types and how they apply to different application scenarios. Only then can you make an informed decision about your database index strategy and design. One thing is for sure: not all indexes are appropriate for all circumstances,...

Tune your Linux Box, not just PostgreSQL

PostgreSQL is one of the leading open-source databases. Out of the box, the default PostgreSQL configuration is not tuned for any particular workload. The default configuration is designed in such a way that PostgreSQL can run on any system using minimum resources. Consequently, a default installation of PostgreSQL does not give optimum performance on high-performance machine because it is set up to use all available resources. PostgreSQL provides mechanisms that allow you to tune your...

Deep dive on SQL codes while migrating from enterprise databases to PostgreSQL

We have quite a lot of tools and services available in the market to migrate applications and databases from enterprise databases (like Oracle, SQLServer, Sybase, etc) to open-source databases. However, many a times, these tools do not do the complete code conversion compatible with the target open source. Manual intervention is necessary and the procedures and functions need to be reviewed line by line and rewritten to provide the same functionality. If database migration is done right,...

Where to stay in Beijing

Haidilao Hot Pot (ZiZhuQiao)

The restaurant is close to Shangri-La hotel.


One of the world’s most loved hot pot chains.

Hai Di Lao began in 1994 in Sichuan Province, in China. Their first U.S. location opened in 2013 in Los Angeles. They also have locations in Japan, Hong Kong, Singapore, South Korea, and Taiwan.

The name “haidilao” means “fortune,” and is a term used in the game of mahjong in Sichuan. You’ll also see the name written as simply Haidilao with no spaces; that’s the formal name of the restaurant’s operating company.

Offering a selection of boiling soup bases, such as tomato, spicy butter, and the traditional oil, Haidilao is a classic hot pot set up: You pick your soup and cook your proteins and veg at your table.

But Haidilao is really known for going the extra mile to keep customers happy. As in you can actually get a manicure while you’re waiting for your table. The business itself touts their sweet extras on their Yelp page for the forthcoming Richmond location: “Haidilao is known for their focus on customer service and for offering a variety of free services and entertainment for customers that include: board games, snacks, and manicures for waiting customers.”
