Method Detail

setShardProvider

public SpannerTableTailer.Builder setShardProvider(ShardProvider provider)

Sets the ShardProvider that this SpannerTableTailer should use.

setCommitTimestampRepository

public SpannerTableTailer.Builder setCommitTimestampRepository(CommitTimestampRepository repository)

Sets the CommitTimestampRepository to use with this SpannerTableTailer.

If none is set, it will default to a SpannerCommitTimestampRepository which stores the last seen commit timestamp in a table named LAST_SEEN_COMMIT_TIMESTAMPS. The table will be created if it does not yet exist.

setPollInterval

public SpannerTableTailer.Builder setPollInterval(org.threeten.bp.Duration interval)

Sets the poll interval for the table. Defaults to 1 second.

setExecutor

public SpannerTableTailer.Builder setExecutor(ScheduledExecutorService executor)

Sets the executor to use to poll the table and to execute the SpannerTableChangeWatcher.RowChangeCallbacks. Defaults to a single daemon threaded executor that is exclusively used for this SpannerTableTailer.

setCommitTimestampColumn

public SpannerTableTailer.Builder setCommitTimestampColumn(String column)

This should only be set if your table contains more than one commit timestamp column.

Sets the commit timestamp column to use. It is only necessary to set this property if the table contains more than one column with the allow_commit_timestamp=true option. If the table only contains one column that can hold a commit timestamp, the SpannerTableTailer will find the column automatically.

build

public SpannerTableTailer build()

Creates the SpannerTableTailer.
