Method Detail

createTable

void createTable(boolean ifNotExists,
                 CqlIdentifier tableName,
                 Class<?> entityClass,
                 Map<String,Object> optionsByName)

Create a table with the name given and fields corresponding to the given class. If the table already exists and parameter ifNotExists is true, this is a no-op and false is returned. If the table doesn't exist, parameter ifNotExists is ignored, the table is created and true is returned.

Parameters:

ifNotExists - If true, will only create the table if it doesn't exist, else the create operation will be ignored and the method will return false.

tableName - The name of the table.

entityClass - The class whose fields determine the columns created.

optionsByName - Table options, given by the string option name and the appropriate option value.

dropTable

void dropTable(CqlIdentifier tableName)

Drops the named table.

Parameters:

tableName - The name of the table.

getTableMetadata

Optional<com.datastax.driver.core.TableMetadata> getTableMetadata(String keyspace,
                                                                  CqlIdentifier tableName)

Lookup TableMetadata.

Parameters:

keyspace - must not be empty or null.

tableName - must not be null.

Returns:

the TableMetadata or null.
