In order to enable debugging for your Django app running in a Docker container, follow these steps using Visual Studio (Code):
- Add
ptvsd
to your requirements.txt file
ptvsd == 4.3.2
- To your
launch.json
, add this:
## Consumer Throughput: Single consumer thread, no compression | |
## Consumer Throughput: 3 consumer thread, no compression | |
bin/kafka-consumer-perf-test.sh --topic benchmark-3-3-none \ | |
--zookeeper kafka-zk-1:2181,kafka-zk-2:2181,kafka-zk-3:2181 \ | |
--messages 15000000 \ | |
--threads 1 |
Once in a while, you may need to cleanup resources (containers, volumes, images, networks) ...
// see: https://github.com/chadoe/docker-cleanup-volumes
$ docker volume rm $(docker volume ls -qf dangling=true)
$ docker volume ls -qf dangling=true | xargs -r docker volume rm
Picking the right architecture = Picking the right battles + Managing trade-offs
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)I have moved this over to the Tech Interview Cheat Sheet Repo and has been expanded and even has code challenges you can run and practice against!
