Line data Source code
1 : //! This program dumps a remote Postgres database into a local Postgres database
2 : //! and uploads the resulting PGDATA into object storage for import into a Timeline.
3 : //!
4 : //! # Context, Architecture, Design
5 : //!
6 : //! See cloud.git Fast Imports RFC (<https://github.com/neondatabase/cloud/pull/19799>)
7 : //! for the full picture.
8 : //! The RFC describing the storage pieces of importing the PGDATA dump into a Timeline
9 : //! is publicly accessible at <https://github.com/neondatabase/neon/pull/9538>.
10 : //!
11 : //! # This is a Prototype!
12 : //!
13 : //! This program is part of a prototype feature and not yet used in production.
14 : //!
15 : //! The cloud.git RFC contains lots of suggestions for improving e2e throughput
16 : //! of this step of the timeline import process.
17 : //!
18 : //! # Local Testing
19 : //!
20 : //! - Comment out most of the pgxns in compute-node.Dockerfile to speed up the build.
21 : //! - Build the image with the following command:
22 : //!
23 : //! ```bash
24 : //! docker buildx build --platform linux/amd64 --build-arg DEBIAN_VERSION=bullseye --build-arg GIT_VERSION=local --build-arg PG_VERSION=v14 --build-arg BUILD_TAG="$(date --iso-8601=s -u)" -t localhost:3030/localregistry/compute-node-v14:latest -f compute/compute-node.Dockerfile .
25 : //! docker push localhost:3030/localregistry/compute-node-v14:latest
26 : //! ```
