    • getPrimaryKeys

      public CompletableFuture<Collection<org.apache.ignite.internal.jdbc.proto.event.JdbcPrimaryKeyMeta>> getPrimaryKeys(String schemaNamePtrn, String tblNamePtrn)
      See DatabaseMetaData.getPrimaryKeys(String, String, String) for details.

      Ignite has only one possible CATALOG_NAME, it is handled on the client (driver) side.

      Parameters:
      schemaNamePtrn - Sql pattern for schema name.
      tblNamePtrn - Sql pattern for table name.
      Returns:
      Future of the collection of primary keys information for tables that matches specified schema and table name patterns.

    • getTablesMeta

      public CompletableFuture<List<org.apache.ignite.internal.jdbc.proto.event.JdbcTableMeta>> getTablesMeta(String schemaNamePtrn, String tblNamePtrn, @Nullable @Nullable String[] tblTypes)
      See DatabaseMetaData.getTables(String, String, String, String[]) for details.

      Ignite has only one possible value for CATALOG_NAME and has only one table type so these parameters are handled on the client (driver) side.

      Result is ordered by (schema name, table name).

      Parameters:
      schemaNamePtrn - Sql pattern for schema name.
      tblNamePtrn - Sql pattern for table name.
      tblTypes - Requested table types.
      Returns:
      Future of the list of metadatas of tables that matches.

    • getColumnsMeta

      public CompletableFuture<Collection<org.apache.ignite.internal.jdbc.proto.event.JdbcColumnMeta>> getColumnsMeta(String schemaNamePtrn, String tblNamePtrn, String colNamePtrn)
      See DatabaseMetaData.getColumns(String, String, String, String) for details.

      Ignite has only one possible CATALOG_NAME, it is handled on the client (driver) side.

      Parameters:
      schemaNamePtrn - Schema name java regex pattern.
      tblNamePtrn - Table name java regex pattern.
      colNamePtrn - Column name java regex pattern.
      Returns:
      Future of the list of metadatas about columns that match specified schema/tablename/columnname criterias.

    • getSchemasMeta

      public CompletableFuture<Collection<String>> getSchemasMeta(String schemaNamePtrn)
      See DatabaseMetaData.getSchemas(String, String) for details.

      Ignite has only one possible CATALOG_NAME, it is handled on the client (driver) side.

      Parameters:
      schemaNamePtrn - Sql pattern for schema name filter.
      Returns:
