When developing Web applications, you often have to add search capabilities. I didn't even know what to search, so I drew a magnifying glass on the sketch.
Search is a very important feature, so lucene based tools like Elasticsearch and SOLR become popular. They're all great. But before using these massive "killer" search weapons, you might want to have a lightweight, but good enough search tool.

PostgreSQL is the first choice for open source relational databases, because the MySQL database is now being acquired by Oracle, so let's introduce a tutorial on compiling the PostgreSQL database in CentOS.
ReadLine is an open source Cross-platform library that provides interactive text editing capabilities.
structure is in the generated script mtk_aegisdb_table_ddl.sql, and the generated script has mapped incompatible items among heterogeneous databases such as most data types, but it also requires manual modification of the exported build statement for PostgreSQL. If the condition allows the database to be built in the first time to run this script, check the log

For this reason, I set some standards to compare the performance differences on different operating systems. I use the same hardware and software to obtain
