Examples of org.kiji.schema.layout.impl.HBaseTableLayoutDatabase

org.kiji.schema.layout.impl.HBaseTableLayoutDatabase

Manages Kiji table layouts using a column family in an HBase table as a backing store.

The HTable row key is the name of the table, and the row has 3 columns:
the layout update, as specified by the user/submitter;
the effective layout after applying the update;
a hash of the effective layout.

Layouts and layout updates are encoded as Kiji cells, using Avro schema hashes, and as TableLayoutDesc Avro records.

A static method, getHColumnDescriptor returns the description of an HColumn that should be used to construct the HTable for the backing store.

      throws IOException {
    this(
        kijiURI,
        htable,
        new HBaseTableLayoutDatabase(kijiURI, htable, LAYOUT_COLUMN_FAMILY, schemaTable),
        new HBaseTableKeyValueDatabase(htable, META_COLUMN_FAMILY));
  }
