Jacob BarzeeandGitHub 06171037f0 Import alignment (#6426)
## What changed?
Make import formatting a part of the build, and test validity with
"ensure-no-changes" target

## Why?
So we never discuss import order again (hopefully)

## How did you test it?
its a build change, so the build will test it!

## Potential risks
As long as build works, the only thing I risk is the ire of coworker who
want imports to be different ;)

## Documentation
N/A

## Is hotfix candidate?
No

Using the cassandra schema tool

This package contains the tooling for temporal cassandra operations.

For localhost development

For the very first time run:

make

then run:

make install-schema-cass

to create schema in your cassandra instance.

For production

Create the binaries

  • Run make
  • You should see an executable temporal-cassandra-tool

Do one time database creation and schema setup for a new cluster

This uses Cassandra's SimpleStratagey for replication. For production, we recommend using a replication factor of 3 with NetworkTopologyStrategy.

temporal-cassandra-tool --ep $CASSANDRA_SEEDS create -k $KEYSPACE --rf $RF

See https://www.ecyrd.com/cassandracalculator for an easy way to determine how many nodes and what replication factor you will want to use. Note that Temporal by default uses LOCAL_QUORUM and LOCAL_SERIAL for read and write consistency.

./temporal-cassandra-tool -ep 127.0.0.1 -k temporal setup-schema -v 0.0 -- this sets up just the schema version tables with initial version of 0.0
./temporal-cassandra-tool -ep 127.0.0.1 -k temporal update-schema -d ./schema/cassandra/temporal/versioned -- upgrades your schema to the latest version

Update schema as part of a release

You can only upgrade to a new version after the initial setup done above.

./temporal-cassandra-tool -ep 127.0.0.1 -k temporal update-schema -d ./schema/cassandra/temporal/versioned -v x.x    -- executes the upgrade to version x.x
