The goal of this change is to improve the storagenode_storage_tallies table by removing the unneeded id column that is not being used but only taking up space, and also to add an index on a different column that needs it. Removing and adding a column seems simple, but ended up being more complicated because of some cockroachdb limitations. The cockroachdb limitation when trying to remove a column from a table and create a new primary key are: 1. only allows primary key creation at table creation time (docs: https://www.cockroachlabs.com/docs/stable/primary-key.html) 2. table drop or rename is performed async and cannot be done in a transaction (issue: https://github.com/cockroachdb/cockroach/issues/12123, https://github.com/cockroachdb/cockroach/issues/22868) To address these differences between cockroachdb and Postgres, this PR performs different migrations for the two database. The Postgres migration is straight forward and what you would expect, but the cockroach migration has two main changes: 1. To change a primary key, use the recommended process from the cockroachdb docs to create a new table with the new primary key you want and then migrate the data. 2. In order to do 1, we needed to do the new table renaming in a separate transaction from the data migration. Ref: SM-65 Change-Id: Idc9aee3ab57aa4d5570e3d2980afea853cd966bf |

Storj V3 Network
Storj is building a decentralized cloud storage network. Check out our white paper for more info!
Storj is an S3-compatible platform and suite of decentralized applications that allows you to store data in a secure and decentralized manner. Your files are encrypted, broken into little pieces and stored in a global decentralized network of computers. Luckily, we also support allowing you (and only you) to retrieve those files!

Contributing to Storj
All of our code for Storj v3 is open source. Have a code change you think would make Storj better? Please send a pull request along! Make sure to sign our Contributor License Agreement (CLA) first. See our license section for more details.
Have comments or bug reports? Want to propose a PR before hand-crafting it? Jump on to our forum and join the Engineering Discussions to say hi to the developer community and to talk to the Storj core team.
Want to vote on or suggest new features? Post it on ideas.storj.io.
Issue tracking and roadmap
See the breakdown of what we're building by checking out the following resources:
Install required packages
To get started running Storj locally, download and install the latest release of Go (at least Go 1.13) at golang.org.
You will also need Git. (brew install git, apt-get install git, etc).
If you're building on Windows, you also need to install and have gcc setup correctly.
We support Linux, Mac, and Windows operating systems. Other operating systems supported by Go should also be able to run Storj.
Download and compile Storj
Aside about GOPATH: Go 1.11 supports a new feature called Go modules, and Storj has adopted Go module support. If you've used previous Go versions, Go modules no longer require a GOPATH environment variable. Go by default falls back to the old behavior if you check out code inside of the directory referenced by your GOPATH variable, so make sure to use another directory,
unset GOPATHentirely, or setGO111MODULE=onbefore continuing with these instructions.
First, fork our repo and clone your copy of our repository.
git clone git@github.com:<your-username>/storj storj
cd storj
Then, let's install Storj.
go install -v ./cmd/...
Make changes and test
Make the changes you want to see! Once you're done, you can run all of the unit tests:
go test -v ./...
You can also execute only a single test package if you like. For example:
go test ./pkg/identity. Add -v for more informations about the executed unit
tests.
Push up a pull request
Use Git to push your changes to your fork:
git commit -a -m 'my changes!'
git push origin master
Use Github to open a pull request!

License
The network under construction (this repo) is currently licensed with the AGPLv3 license. Once the network reaches beta phase, we will be licensing all client-side code via the Apache v2 license.
For code released under the AGPLv3, we request that contributors sign our Contributor License Agreement (CLA) so that we can relicense the code under Apache v2, or other licenses in the future.
