getMetadataWriter

public final Option<HoodieTableMetadataWriter> getMetadataWriter(String triggeringInstantTimestamp)

Get Table metadata writer.

Parameters:

triggeringInstantTimestamp - - The instant that is triggering this metadata write

Returns:

instance of HoodieTableMetadataWriter

isTableServiceAction

public abstract boolean isTableServiceAction(String actionType)

Check if action type is a table service.

Parameters:

actionType - action type of interest.

Returns:

true if action represents a table service. false otherwise.

getMetadataWriter

public <R extends org.apache.avro.specific.SpecificRecordBase> Option<HoodieTableMetadataWriter> getMetadataWriter(String triggeringInstantTimestamp,
                                                                                                                   Option<R> actionMetadata)

Get Table metadata writer.

Note: Get the metadata writer for the conf. If the metadata table doesn't exist, this wil trigger the creation of the table and the initial bootstrapping. Since this call is under the transaction lock, other concurrent writers are blocked from doing the similar initial metadata table creation and the bootstrapping.

Parameters:

triggeringInstantTimestamp - - The instant that is triggering this metadata write

Returns:

instance of HoodieTableMetadataWriter

maybeDeleteMetadataTable

public void maybeDeleteMetadataTable()

Deletes the metadata table if the writer disables metadata table with hoodie.metadata.enable=false
