Using English characters to prevent garbled characters
to fix garbled characters
Stream as Table: A stream can be considered a changelog of a table,
where each data record in the stream captures a state change of the table. A
stream is thus a table in disguise, and it can be easily turned into a
é¥æ¸ealé¥ï¿½ table by replaying the changelog from beginning to end to
reconstruct the table. Similarly, in a more general analogy, aggregating data
records in a stream é¥ï¿½ such as computing the total number of pageviews by
user from a stream of pageview events é¥ï¿½ will return a table (here with the
key and the value being the user and its corresponding pageview count,
respectively).
Table as Stream: A table can be considered a snapshot, at a point in
time, of the latest value for each key in a stream (a stream's data records are
key-value pairs). A table is thus a stream in disguise, and it can be easily
turned into a é¥æ¸ealé¥ï¿½ stream by iterating over each key-value entry in
the table.
