Database Concerns for Corda Enterprise Nodes
|
||||
============================================
|
||||
|
||||
Corda - the platform, and the installed third-party CorDapps store their data in a relational database (see :doc:`api-persistence`).
|
||||
|
||||
When Corda is first installed, or when a new CorDapp is installed, associated tables, indexes, foreign-keys, etc must be created.
|
||||
|
||||
Similarly, when Corda is upgraded, or when a new version of a CorDapp is installed, their database schemas may have changed,
|
||||
but the existing data needs to be preserved or changed accordingly.
|
||||
|
||||
Corda supports multiple database management systems, so CorDapp developers need to keep this database portability requirement in mind when writing and testing the code.
|
||||
|
||||
To address these concerns, Corda Enterprise provides a mechanism to make it straightforward to migrate from the old schemas to the new ones whilst preserving data.
|
||||
It does this by integrating a specialised database migration library.
|
||||
|
||||
Also Corda Enterprise makes it easy to "lift" a CorDapp that does not handle the database migration (e.g.: the CorDapp developers did not include db migration scripts)
|
||||
|
||||
This document is addressed to Node Administrators and CorDapp developers.

|
||||

Database Migration
|
||||
==================
|
||||

|
||||
that a Corda Node uses when new releases of Corda or CorDapps are installed.

|
||||
foreign-keys, etc. must be created. Similarly, when Corda is upgraded, or when a new version of a CorDapp is installed,
|
||||
their database schemas may have changed, but the existing data needs to be preserved or changed accordingly.
|
||||
|
||||
On a high level, this means that the corda binaries will ship with scripts that cover everything from the creation of the schema
|
||||
for the initial install to changes on subsequent versions.

About Liquibase
|
||||
---------------
|
||||
|
||||
Liquibase is a generic framework to implement an automated, version based database migration framework that supports a large number of databases.
|
||||
Liquibase is a tool that implements an automated, version based database migration framework with support for a
|
||||
large number of databases. It works by maintaining a list of applied changesets. A changeset can be something very
|
||||
simple like adding a new column to a table. It stores each executed changeset with columns like id, author, timestamp,
|
||||
description, md5 hash, etc in a table called ``DATABASECHANGELOG``. This changelog table will be read every time a
|
||||
migration command is run to determine what changesets need to be executed. It represents the "version" of the database
|
||||
(the sum of the executed changesets at any point). Changesets are scripts written in a supported format (xml, yml,
|
||||
sql), and should never be modified once they have been executed. Any necessary correction should be applied in a new
|
||||
changeset.
|
||||
|
||||
It works by maintaining a list of applied change sets.
|
||||
For documentation around Liquibase see: `The Official website <http://www.liquibase.org>`_ and `Tutorial <https://www.thoughts-on-java.org/database-migration-with-liquibase-getting-started>`_.

Integration with the Corda node

||||
===============================
|
||||
-------------------------------
|

|
||||
Operational
|
||||
-----------
|
||||
By default, a node will *not* attempt to execute database migration scripts at startup (even when a new version has been deployed), but will check the database "version" (see above),
|
||||
and halt if the database is not in sync with the node, to avoid data corruption.
|
||||
|
||||
To bring the database to the correct state we provide an advanced migration tool. (see below)
|
||||
|
||||
Running the migration at startup automatically can be configured by specifying true in the ``database.runMigration`` node configuration setting (default behaviour is false).
|
||||
|
||||
We recommend Node administrators to leave the default behaviour in production, and use the migration tool to have better control. (See below)
|
||||
|
||||
It is safe to run at startup if you have implemented the usual best practices for database management ( e.g. running a backup before installing a new version, etc).

Migration scripts structure
|
||||
---------------------------
|
||||
Corda provides migration scripts in an XML format for its internal node and vault tables.
|
||||
CorDapps should provide migration scripts for the tables they manage.
|
||||
|
||||
In Corda, ``MappedSchemas`` (see :doc:`api-persistence`) manage JPA Entities and thus the corresponding database tables.
|
||||
So ``MappedSchemas`` are the natural place to point to the changelog file(s) that contain the changesets for those tables.
|
||||
|
||||
Nodes can configure which ``MappedSchemas`` are included which means only the required tables are created.
|
||||
|
||||
To follow standard best practices, our convention for structuring the changelogs is to have a "master" changelog file per ``MappedSchema`` that will only include release changelogs. (see example below )

Migration tool
|
||||
--------------
|
||||
|

The migration tool is distributed as a standalone jar file named ``db-migration-tool-${corda_version}.jar``.
|
||||
It is intended to be used by Corda Enterprise node administrators.
|
||||
|
||||
Currently it has these features:
|
||||
1. It allows running the migration on the database (`--execute-migration` )
|
||||
2. Offers the option to inspect the actual sql statements that will be run as part of the current migration (`--dry-run` )

||||
1. It allows running the migration on the database (``--execute-migration`` )
|
||||
2. Offers the option to inspect the actual SQL statements that will be run as part of the current migration (``--dry-run`` )
|
||||
3. Sometimes, when a node or the migration tool crashes while running migrations, Liquibase will not release the lock.
|
||||
This can happen during some long database operation, or when an admin kills the process.
|
||||
( This cannot happen during normal operation of a node. Only during the migration process.)
|
||||
See: <http://www.liquibase.org/documentation/databasechangeloglock_table.html>.
|
||||
The tool provides a "release-lock" command that would forcibly unlock the db migration.

using this tool, the CorDapp can be "lifted" (`--create-migration-sql-for-cordapp`).

using this tool, the CorDapp can be "lifted" (``--create-migration-sql-for-cordapp``).

=======
|
||||
Examples
|
||||
--------
|
||||
|
||||
Node Administrator installing Corda for the first time
|
||||
------------------------------------------------------
|
||||
- run normal installations steps
|
||||
- Using the db migration tool attempt a dry-run to inspect the output sql
|
||||
``--base-directory /path/to/node --dry-run``
|
||||
- The output sql from the above command can be executed directly on the database or this command can be run:
|
||||
``--base-directory /path/to/node --execute-migration``
|
||||
- At this point the corda node can be started successfully

Node Administrator installing new version of Corda
|

--------------------------------------------------
|
||||
- deploy new version of Corda
|
||||
- attempt to start node. If there are db migrations in the new release, then the node will exit and will show how many changes are needed
|
||||
- The same steps as above can be executed: dry-run and/or execute-migration
|
||||
The output sql from the above command can be executed directly on the database or this command can be run::
|
||||

Node Administrator installing new CorDapp
|

|
||||
- same steps as above
|
||||

|
||||
|
||||
When upgrading, deploy the new version of Corda. Attempt to start the node. If there are database migrations in the new
|
||||
release, then the node will exit and will show how many changes are needed. You can then use the same commands
|

as above, either to do a dry run or execute the migrations.

|

|

To help Corda Enterprise users, we offer support in the migration tool for "lifting" a CorDapp to support Liquibase.
|
||||
|
||||
These are the steps:
|
||||
- deploy the CorDapp on your node (copy the jar in the `cordapps` folder)
|
||||
- find out the name of the MappedSchema containing the new contract state entities.
|
||||
- call the migration tool: ``--base-directory /path/to/node --create-migration-sql-for-cordapp com.example.MyMappedSchema``
|
||||
- this will generate a file called ``my-mapped-schema.changelog-master.sql`` in a folder called ``migration`` in the `base-directory`
|
||||
- in case you don't specify the actual MappedSchema name, the tool will generate one sql file for each schema defined in the CorDapp
|
||||
- inspect the file(s) to make sure it is correct. This is a standard sql file with some liquibase metadata as comments.
|
||||
- create a jar with the `migration` folder (by convention it could be named: originalCorDappName-migration.jar), and deploy this jar together with the CorDapp
|
||||
- To make sure that the new migration will be used, the migration tool can be run in a `dry-run` mode and inspect the output file
|
||||
|
||||
1. Deploy the CorDapp on your node (copy the jar into the ``cordapps`` folder)
|
||||
2. Find out the name of the ``MappedSchema`` containing the new contract state entities.
|
||||
3. Call the migration tool: ``--base-directory /path/to/node --create-migration-sql-for-cordapp com.example.MyMappedSchema``
|
||||
This will generate a file called ``my-mapped-schema.changelog-master.sql`` in a folder called ``migration`` in the ``base-directory``.
|
||||
In case you don't specify the actual ``MappedSchema`` name, the tool will generate one SQL file for each schema defined in the CorDapp
|
||||
4. Inspect the file(s) to make sure it is correct. This is a standard SQL file with some Liquibase metadata as comments.
|
||||
5. Create a jar with the ``migration`` folder (by convention it could be named: ``originalCorDappName-migration.jar``),

6. To make sure that the new migration will be used, do a dry run with the migration tool and inspect the output file.

CorDapp developers who decide to store contract state in custom entities can create migration files for the ``MappedSchema`` they define.

There are 2 ways of associating a migration file with a schema:
|
||||
1) By overriding ``val migrationResource: String`` and pointing to a file that needs to be in the classpath
|

2) By putting a file on the classpath in a `migration` package whose name is the hyphenated name of the schema. (All supported file extensions will be appended to the name)

CorDapp developers can use any of the supported formats (xml, sql, json, yaml) for the migration files they create.

|
||||
|
||||
Supporting the messaging layer is a network map service, which is responsible for tracking public nodes on the network.
|
||||
|
||||
Nodes have an internal component, the network map cache, which contains a copy of the network map (which is just a
|
||||
document). When a node starts up its cache fetches a copy of the full network map, and requests to be notified of
|
||||
changes. The node then registers itself with the network map service, and the service notifies subscribers that a new
|
||||
node has joined the network. Nodes do not automatically deregister themselves, so (for example) nodes going offline
|
||||
briefly for maintenance are retained in the network map, and messages for them will be queued, minimising disruption.
|
||||
Nodes have an internal component, the network map cache, which contains a copy of the network map (which is backed up in the database
|
||||
to persist that information across the restarts in case the network map server is down). When a node starts up its cache
|
||||
fetches a copy of the full network map (from the server or from filesystem for development mode). After that it polls on
|
||||
regular time interval for network map and applies any related changes locally.
|
||||
Nodes do not automatically deregister themselves, so (for example) nodes going offline briefly for maintenance are retained
|
||||
in the network map, and messages for them will be queued, minimising disruption.
|
||||
|
||||
Nodes submit signed changes to the map service, which then forwards update notifications on to nodes which have
|
||||
requested to be notified of changes.
|
||||
|
||||
The network map currently supports:
|
||||
|
||||
* Looking up nodes by service
|
||||
* Looking up node for a party
|
||||
* Suggesting a node providing a specific service, based on suitability for a contract and parties, for example suggesting
|
||||
an appropriate interest rates oracle for an interest rate swap contract. Currently no recommendation logic is in place.
|
||||
Additionally, on every restart and on daily basis nodes submit signed `NodeInfo`s to the map service. When network map gets
|
||||
signed, these changes are distributed as new network data. `NodeInfo` republishing is treated as a heartbeat from the node,
|
||||
based on that network map service is able to figure out which nodes can be considered as stale and removed from the network
|
||||
map document after `eventHorizon` time.

Cleaning the network map cache
|
||||
------------------------------
|
||||
|
||||
Sometimes it may happen that the node ends up with an inconsistent view of the network. This can occur due to changes in deployment
|
||||
leading to stale data in the database, different data distribution time and mistakes in configuration. For these unlikely
|
||||
events both RPC method and command line option for clearing local network map cache database exist. To use them
|

you either need to run from the command line:
|
||||
|
||||
.. code-block:: shell
|
||||
|
||||
java -jar corda.jar --clear-network-map-cache
|
||||
|
||||
or call RPC method `clearNetworkMapCache` (it can be invoked through the node's shell as `run clearNetworkMapCache`, for more information on
|
||||
how to log into node's shell see :doc:`shell`). As we are testing and hardening the implementation this step shouldn't be required.
|
||||
After cleaning the cache, network map data is restored on the next poll from the server or filesystem.
