方法详细资料

close

protected void close()

write

public void write(TimestreamIdentifier identifier,
                  Point point)

Synchronously write data, and if the data writing fails, an exception will be thrown.

参数:

identifier - Timeline identifier

point - Data point

asyncWrite

public void asyncWrite(TimestreamIdentifier identifier,
                       Point point)

Asynchronously write data, if the write fails, it needs to be obtained through TableStoreCallback

Asynchronous interface, writes data via TableStoreWriter. Compared to synchronous interfaces, this interface offers better throughput for data writing.

Note: If the buffer of TableStoreWriter is full, this operation will be blocked.

参数:

identifier - Timeline identifier

point - Data point

get

public DataGetter get(TimestreamIdentifier identifier)

Query a single timeline data

参数:

identifier - The timeline identifier

返回:

flush

public void flush()

Write all the data cached in memory to the database
