Thread Pools

Thread pools on the JVM should usually be divided into the following three categories:

1. CPU-bound
2. Blocking IO
3. Non-blocking IO polling

Each of these categories has a different optimal configuration and usage pattern.

//load Global Terrorism Database
//Copy/Paste the load script below into your Neo4j-shell command-line utility

//In order to accelerate the loading process, you want to download the CSV file from
//https://www.dropbox.com/s/oequ58lrp8f9w6v/gtdb_transform.csv?dl=1 and then to a local file.
//After that, you would of course need to replace the URL in all of the queries below, and replace it with 
//load csv with headers from "file:/path/to/your/file.csv" as csv

//load the countries

Switch to mysql_native_password plugin

By default MariaDB use the unix_socket plugin to authenticate users.

But it's easier to use mysql_native_password for dev (and only for dev because it's way less secure).

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

• -E: will describe the underlaying queries of the \ commands (cool for learning!)
• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

# This is just a cheat sheet:

# On production
sudo -u postgres pg_dump database | gzip -9 > database.sql.gz

# On local
scp -C production:~/database.sql.gz
dropdb database && createdb database
gunzip < database.sql.gz | psql database

docker exec CONTAINER /usr/bin/mysqldump -u root --password=root DATABASE > backup.sql
