Currently, the tests don't work in parallel. The tests try to create a data directory in the same path and clash with each other. That should be fixed, but for now, let's at least fix the instructions on how it works now.

# Zenith
|
|
|
|
Zenith substitutes PostgreSQL storage layer and redistributes data across a cluster of nodes
|
|
|
|
## Running tests
|
|
|
|
```sh
|
|
git clone --recursive https://github.com/libzenith/zenith.git
|
|
./pgbuild.sh # builds postgres and installs it to ./tmp_install
|
|
cargo test -- --test-threads=1
|
|
```
|
|
|
|
## Source tree layout
|
|
|
|
/walkeeper:
|
|
|
|
WAL safekeeper. Written in Rust.
|
|
|
|
/pageserver:
|
|
|
|
Page Server. Written in Rust.
|
|
|
|
Depends on the modified 'postgres' binary for WAL redo.
|
|
|
|
/integration_tests:
|
|
|
|
Tests with different combinations of a Postgres compute node, WAL safekeeper and Page Server.
|
|
|
|
/mgmt-console:
|
|
|
|
Web UI to launch (modified) Postgres servers, using S3 as the backing store. Written in Python.
|
|
This is somewhat outdated, as it doesn't use the WAL safekeeper or Page Servers.
|
|
|
|
/vendor/postgres:
|
|
|
|
PostgreSQL source tree, with the modifications needed for Zenith.
|
|
|
|
/vendor/postgres/src/bin/safekeeper:
|
|
|
|
Extension (safekeeper_proxy) that runs in the compute node, and connects to the WAL safekeepers
|
|
and streams the WAL
|
