Example 1 with PartialIndexDefinitionBuilder

use of org.apache.ignite.schema.definition.builder.PartialIndexDefinitionBuilder in project ignite-3 by apache.

the class SchemaConfigurationConverterTest method testPartialIndex.

/**
 * Add/remove PartialIndex into configuration and read it back.
 */
@Test
public void testPartialIndex() throws Exception {
    PartialIndexDefinitionBuilder builder = SchemaBuilders.partialIndex("TEST");
    builder.addIndexColumn("A").done();
    builder.withExpression("WHERE A > 0");
    PartialIndexDefinition idx = builder.build();
    getTbl().change(ch -> SchemaConfigurationConverter.addIndex(idx, ch)).get();
    TableDefinition tbl = SchemaConfigurationConverter.convert(getTbl().value());
    PartialIndexDefinition idx2 = (PartialIndexDefinition) getIdx(idx.name(), tbl.indices());
    assertNotNull(idx2);
    assertEquals("PARTIAL", idx2.type());
    assertEquals(idx.columns().size(), idx2.columns().size());
}

Example 2 with PartialIndexDefinitionBuilder

use of org.apache.ignite.schema.definition.builder.PartialIndexDefinitionBuilder in project ignite-3 by apache.
