README

vaults-cli

License standard-readme compliant

Continuously publish data from your database or file uploads to the Tableland Vaults network.

Table of Contents

Background

Textile Vaults is a secure and verifiable open data platform. The Vaults CLI is a tool that allows you to continuously replicate a table or view from your database to the network (currently, only PostgreSQL is supported). Or, you can directly upload files to the vault (currently, parquet is only supported)

🚧 Vaults is currently not in a production-ready state. Any data that is pushed to the network may be subject to deletion. 🚧

Usage

Install

You can either install the CLI from the remote source:

go install github.com/tablelandnetwork/basin-cli/cmd/vaults@latest

Or clone from source and run the Makefile install command:

git clone https://github.com/tablelandnetwork/basin-cli.git
cd basin-cli
make install
Postgres Setup
Self-hosted
  • Make sure you have access to a superuser role. For example, you can create a new role such as CREATE ROLE vaults WITH PASSWORD NULL LOGIN SUPERUSER;.

  • Check that your Postgres installation has the wal2json plugin installed.

  • Check if logical replication is enabled:

    SHOW wal_level;
    

    The wal_level setting must be set to logical: ALTER SYSTEM SET wal_level = logical;.

  • Restart the database in order for the new wal_level to take effect (be careful!).

Amazon RDS
  • Make sure you have a user with the rds_superuser role, and use psql to connect to your database.

    psql -h [HOST] -U [USER] -d [DATABASE]
    
  • Check if logical replication is enabled:

    SELECT name, setting
    FROM pg_settings
    WHERE name = 'rds.logical_replication';
    
  • If it's on, go to Create a vault

  • If it's off, follow the next steps:

  • After reboot, check if logical replication is enabled

Supabase
  • Log into the Supabase dashboard and go to your project, or create a new one.
  • Check if logical replication is enabled. This should be the default setting, so you shouldn't have to change anything. You can do this in the SQL Editor section on the left hand side of the Supabase dashboard by running SHOW wal_level; query, which should log logical.
  • You can find the database connection information on the left hand side under Project Settings > Database. You will need the Host, Port, Database, Username, and Password to connect to your database.
Create a vault

Vaults define the place you push data into.

Vaults uses public key authentication, so you will need an Ethereum style (ECDSA, secp256k1) wallet to create a new vault. You can use an existing wallet or set up a new one with vaults wallet create. Your private key is only used locally for signing.

vaults account create [FILENAME]

A new private key will be written to FILENAME.

The name of a vault contains a namespace (e.g. my_company) and the name of an existing database relation (e.g. my_table), separated by a period (.). Use vaults create to create a new vault. See vaults create --help for more info.

vaults create  --account [WALLET_ADDRESS] namespace.relation_name

🚧 Vaults currently only replicates INSERT statements, which means that it only replicates append-only data (e.g., log-style data). Row updates and deletes will be ignored. 🚧

Start replicating a database

Use vaults stream to start a daemon that will continuously push changes to the underlying table/view to the network. See vaults stream --help for more info.

vaults stream --dburi [DB_URI] --tables t1,t2 --private-key [PRIVATE_KEY] namespace.relation_name

The --dburi should follow this format:

postgresql://[USER]:[PASSWORD]@[HOST]:[PORT]/[DATABASE]
Write a Parquet file

Before writing a Parquet file, you need to Create a vault, if not already created. Then, use vaults write to write a Parquet file.

vaults write --vault [namespace.relation_name] --private-key [PRIVATE_KEY] filepath

You can attach a timestamp to that file write, e.g.

vaults write --vault [namespace.relation_name] --private-key [PRIVATE_KEY] --timestamp 1699984703 filepath

# or use data format
vaults write --vault [namespace.relation_name] --private-key [PRIVATE_KEY] --timestamp 2006-01-02 filepath

# or use RFC3339 format
vaults write --vault [namespace.relation_name] --private-key [PRIVATE_KEY] --timestamp 2006-01-02T15:04:05Z07:00 filepath

If a timestamp is not provided, the CLI will assume the timestamp is the current client epoch in UTC.

Listing Vaults

You can list the vaults from an account by running:

vaults list --account [ETH_ADDRESS]
Listing Events

You can list events of a given vault by running:

vaults events --vault [VAULT_NAME] --latest 5

Events command accept --before,--after , and --at flags to filter events by timestamp

# examples
vaults events --vault demotest.data --at 1699569502
vaults events --vault demotest.data --before 2023-11-09T19:38:23-03:00
vaults events --vault demotest.data --after 2023-11-09
Retrieving

You can retrieve a file from a vault by running:

vaults retrieve bafybeifr5njnrw67yyb2h2t7k6ukm3pml4fgphsxeurqcmgmeb7omc2vlq

You can specify the file where the retrieved content will be save:

vaults retrieve --output filename bafybeifr5njnrw67yyb2h2t7k6ukm3pml4fgphsxeurqcmgmeb7omc2vlq

Development

Running

You can make use of the scripts inside scripts to facilitate running the CLI locally without building.

# Starting the Provider Server
PORT=8888 ./scripts/server.sh

# Create an account
./scripts/run.sh account create pk.out

# Start replicating
./scripts/run.sh vaults stream --dburi [DB_URI] --tables t1,t2 --private-key [PRIVATE_KEY] namespace.relation_name
Run tests
make test

Note: One of the tests requires Docker Engine to be running.
