Method Detail

readTablet

public TabletMetadata readTablet(KeyExtent extent,
                                 Ample.ReadConsistency readConsistency,
                                 TabletMetadata.ColumnType... colsToFetch)

Description copied from interface: Ample

Read a single tablets metadata. No checking is done for prev row, so it could differ.

Specified by:

readTablet in interface Ample

Parameters:

extent - Reads tablet metadata using the table id and end row from this extent.

readConsistency - Controls how the data is read.

colsToFetch - What tablets columns to fetch. If empty, then everything is fetched.

readTablets

public TabletsMetadata.TableOptions readTablets()

Description copied from interface: Ample

Entry point for reading multiple tablets' metadata. Generates a TabletsMetadata builder object and assigns the AmpleImpl client to that builder object. This allows readTablets() to be called from a ClientContext. Associated methods of the TabletsMetadata Builder class are used to generate the metadata.

Specified by:

readTablets in interface Ample
