Create new database
Example I - Create database
- The following simple example creates a non-sharded database with the default replication factor of 1.
DatabaseRecord databaseRecord = new DatabaseRecord();
databaseRecord.setDatabaseName("MyNewDatabase");
store.maintenance().server().send(new CreateDatabaseOperation(databaseRecord));
Example II - Ensure database does not exist before creating
- To ensure the database does not already exist before creating it, follow this example:
public void ensureDatabaseExists(IDocumentStore store, String database, boolean createDatabaseIfNotExists) {
database = ObjectUtils.firstNonNull(database, store.getDatabase());
if (StringUtils.isBlank(database)) {
throw new IllegalArgumentException("Value cannot be null or whitespace");
}
try {
store.maintenance().forDatabase(database).send(new GetStatisticsOperation());
} catch (DatabaseDoesNotExistException e) {
if (!createDatabaseIfNotExists) {
throw e;
}
try {
DatabaseRecord databaseRecord = new DatabaseRecord();
databaseRecord.setDatabaseName(database);
store.maintenance().server().send(new CreateDatabaseOperation(databaseRecord));
} catch (ConcurrencyException ce) {
// The database was already created before calling CreateDatabaseOperation
}
}
}
Syntax
public CreateDatabaseOperation(DatabaseRecord databaseRecord)
public CreateDatabaseOperation(DatabaseRecord databaseRecord, int replicationFactor)
Parameter | Type | Description |
---|---|---|
databaseRecord | DatabaseRecord | Instance of DatabaseRecord containing database configuration. |
replicationFactor | int | Number of nodes the database should be replicated to. If not specified, the value is taken from topology.replicationFactor ,or defaults to 1 if that is not set.If topology is provided, the replicationFactor is ignored. |
DatabaseRecord
DatabaseRecord
is a collection of database configurations.
constructor | Description |
---|---|
DatabaseRecord(string databaseName) |
Initialize a new database record |
Note:
- Only the properties listed in the table below can be configured in the
DatabaseRecord
object passed toCreateDatabaseOperation
. - For example, although ongoing task definitions are public on the DatabaseRecord class, setting them during database creation will result in an exception. To define ongoing tasks (e.g., backups, ETL, replication), use the appropriate dedicated operation after the database has been created.
