Ledger Databases

Adds support for MySQL, H2, and PostgreSQL databases in Ledger

Use

Common

For both MySQL, H2, and PostgreSQL, you will need to place Ledger Databases in your mods folder along with Ledger 1.1.0 or newer

H2

Add the following to the bottom of your Ledger config file:

[database_extensions]
database = "H2"

MySQL

Add the following to the bottom of your Ledger config file:

[database_extensions]
database = "MYSQL"
url = ""
username = ""
password = ""
properties = []
maxPoolSize = 10
connectionTimeout = 60000

url: Must be URL of database with /<database_name> appended. An example URL would be localhost/ledger. You can optionally add port information such as localhost:3000/ledger

PostgreSQL

[database_extensions]
database = "POSTGRESQL"
url = ""
username = ""
password = ""
properties = []
maxPoolSize = 10
connectionTimeout = 60000

SQLite

[database_extensions]
database = "SQLITE"

Connector properties

For some databases, such as MySQL, you can provide properties to the database connector. For each property, add a string entry to the properties array.

properties = ["useJDBCCompliantTimezoneShift=true", "useLegacyDatetimeCode=false", "serverTimezone=UTC"]
