Method Details

• ​

  getClassSchema

  public static org.apache.avro.Schema getClassSchema()

  This method supports the Avro framework and is not intended to be called directly by the user.

  Returns:

  The schema for the class.

• ​

  getTableNames

  public List<String> getTableNames()

  Names of tables whose metadata will be fetched, each in [schema_name.]table_name format, using standard name resolution rules. All provided tables must exist, or an error is returned. A single entry of ’*’ expands to every user table the caller may read (excluding system schemas, views, and temporary tables); when used it must be the only entry.

  Returns:

  The current value of tableNames.

• ​

  setTableNames

  public ShowStatisticsRequest setTableNames(List<String> tableNames)

  Names of tables whose metadata will be fetched, each in [schema_name.]table_name format, using standard name resolution rules. All provided tables must exist, or an error is returned. A single entry of ’*’ expands to every user table the caller may read (excluding system schemas, views, and temporary tables); when used it must be the only entry.

  Parameters:

  tableNames - The new value for tableNames.

  Returns:

  this to mimic the builder pattern.

• ​

  getOptions

  public Map<String,String> getOptions()

  Optional parameters.

  • NO_ERROR_IF_NOT_EXISTS: If TRUE and if the table names specified in tableNames does not exist, no error is returned. If FALSE and if the table names specified in tableNames does not exist, then an error is returned. Supported values:
    • TRUE
    • FALSE
    The default value is FALSE.
  • COLUMN_NAMES: Columns, per table in tableNames, to collect statistics for when @input.key options.collect_now is TRUE; ignored otherwise. Encoded as a ’;‘-separated parallel array aligned with tableNames (e.g. ‘x,y;z’ requests columns x,y for the first table and z for the second). A value of ’*’ expands to every collectable column on each table (geometry, vector, JSON, and array columns are skipped). An explicit list may not be combined with a ’*’ table_names wildcard. The default value is ”.
  • COLLECT_NOW: If TRUE, the columns named by @input.key options.column_names are collected synchronously during this request and reflected in the response. Supported values:
    • TRUE
    • FALSE
    The default value is FALSE.

  The default value is an empty Map.

  Returns:

  The current value of options.
