Constructor Detail

Builder

public Builder(CalciteSchema schema,
               String sql)

Method Detail

auto

public Lattice.Builder auto(boolean auto)

Sets the "auto" attribute (default true).

algorithm

public Lattice.Builder algorithm(boolean algorithm)

Sets the "algorithm" attribute (default false).

algorithmMaxMillis

public Lattice.Builder algorithmMaxMillis(long algorithmMaxMillis)

Sets the "algorithmMaxMillis" attribute (default -1).

rowCountEstimate

public Lattice.Builder rowCountEstimate(double rowCountEstimate)

Sets the "rowCountEstimate" attribute (default null).

statisticProvider

public Lattice.Builder statisticProvider(String statisticProvider)

Sets the "statisticProvider" attribute.

If not set, the lattice will use Lattices.CACHED_SQL.

build

public Lattice build()

Builds a lattice.

resolveArgs

public com.google.common.collect.ImmutableList<Lattice.Column> resolveArgs(Object args)

Resolves the arguments of a JsonMeasure. They must either be null, a string, or a list of strings. Throws if the structure is invalid, or if any of the columns do not exist in the lattice.

resolveColumnByAlias

private Lattice.Column resolveColumnByAlias(String name)

Looks up a column in this lattice by alias. The alias must be unique within the lattice.

resolveColumn

public Lattice.Column resolveColumn(Object name)

resolveQualifiedColumn

private Lattice.Column resolveQualifiedColumn(String table,
                                              String column)

resolveMeasure

public Lattice.Measure resolveMeasure(String aggName,
                                      Object args)

resolveAgg

private SqlAggFunction resolveAgg(String aggName)

addMeasure

public void addMeasure(Lattice.Measure measure)

addTile

public void addTile(Lattice.Tile tile)
