Using the SQL schema tool

This package contains the tooling for cadence sql operations. The tooling itself is agnostic of the storage engine behind the sql interface. So, this same tool can be used against, say, OracleDB and MySQLDB

For localhost development

SQL_USER=$USERNAME SQL_PASSWORD=$PASSWD make install-schema-mysql

NOTE: See CONTRIBUTING for prerequisite of make command.

For production

Get the SQL Schema tool

  • Use brew to install CLI: brew install cadence-workflow which includes cadence-sql-tool
    • The schema files are located at /usr/local/etc/cadence/schema/.
    • Follow the instructions if you need to install older versions of schema tools via homebrew. However, easier way is to use new versions of schema tools with old versions of schemas. All you need is to check out the older version of schemas from this repo. Run git checkout v0.21.3 to get the v0.21.3 schemas in the schema folder.
  • Or build yourself, with make cadence-sql-tool. See CONTRIBUTING for prerequisite of make command.

Note: The binaries can also be found in the ubercadence/server docker images

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

  • All command below are taking MySQL as example. For postgres, simply use with "--plugin postgres"
./cadence-sql-tool --ep $SQL_HOST_ADDR -p $port --plugin mysql create-database --db cadence
./cadence-sql-tool --ep $SQL_HOST_ADDR -p $port --plugin mysql create-database --db cadence_visibility

./cadence-sql-tool --ep $SQL_HOST_ADDR -p $port --plugin mysql --db cadence setup-schema -v 0.0 -- this sets up just the schema version tables with initial version of 0.0
./cadence-sql-tool --ep $SQL_HOST_ADDR -p $port --plugin mysql --db cadence update-schema -d ./schema/mysql/v8/cadence/versioned -- upgrades your schema to the latest version

./cadence-sql-tool --ep $SQL_HOST_ADDR -p $port --plugin mysql --db cadence_visibility setup-schema -v 0.0 -- this sets up just the schema version tables with initial version of 0.0 for visibility
./cadence-sql-tool --ep $SQL_HOST_ADDR -p $port --plugin mysql --db cadence_visibility update-schema -d ./schema/mysql/v8/visibility/versioned  -- upgrades your schema to the latest version for visibility

Update schema as part of a release

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

./cadence-sql-tool --ep $SQL_HOST_ADDR -p $port --plugin mysql --db cadence update-schema -d ./schema/mysql/v8/cadence/versioned -v x.x --dryrun -- executes a dryrun of upgrade to version x.x
./cadence-sql-tool --ep $SQL_HOST_ADDR -p $port --plugin mysql --db cadence update-schema -d ./schema/mysql/v8/cadence/versioned -v x.x    -- actually executes the upgrade to version x.x

./cadence-sql-tool --ep $SQL_HOST_ADDR -p $port --plugin mysql --db cadence_visibility update-schema -d ./schema/mysql/v8/cadence/versioned -v x.x --dryrun -- executes a dryrun of upgrade to version x.x
./cadence-sql-tool --ep $SQL_HOST_ADDR -p $port --plugin mysql --db cadence_visibility update-schema -d ./schema/mysql/v8/cadence/versioned -v x.x    -- actually executes the upgrade to version x.x
