Streaming Large JSON Response in Spring.
To put things simply, this method findAllStreaming() takes an OutputStream to write the whole json response into. To write json into the stream chunk by chunk we are using JsonGenerator. JsonGenerator is provided by Jackson-Core. More detailed about how to write stream event is covered in this blog post by the author of the library.

Ryū: fast float-to-string conversion (Java lib, 2018 paper)
Jackson already has some improvements for string-to-number conversion over stock JDK parser (https://github.com/FasterXML/jackson-core/pull/677). Would be great if they added faster number-to-string too.

Python: executing PostgreSQL stored functions which return multiple result sets.
To recap, the source database is the MySQL test data released by Oracle Corporation. Downloadable from https://github.com/datacharmer/test_db. I've migrated it over to PostgreSQL as discussed in pgloader Docker: migrating from Docker & localhost MySQL to localhost PostgreSQL, please see command ❷.

pgloader Docker: migrating from Docker & localhost MySQL to localhost PostgreSQL.
The employees database is a MySQL test data database released by Oracle Corporation. Downloadable from https://github.com/datacharmer/test_db. It is a simple database with only a few tables, easy to setup. The main tables have several hundreds thousand records, which is very good for testing purposes.
