Need help to understand the sentence in DSE Cassandra documentation -

http://www.datastax.com/documentation/cassandra/2.0/cassandra/dml/dml_ltwt_transaction_c.html

The SERIAL sequence level allows the current (and possibly uncommitted) state of the data to be read without suggesting a new addition or update. If the SERIAL read detects an unfinished transaction, it will commit it as part of the read.

What I didn't understand is how can a read operation commit a transaction in progress? Does this mean that he will consider it part of the commit?

Thank you for spotting a problem in the docs. The sentence should say, "If a SERIAL read detects an incomplete transaction, Cassandra will repair the read as part of the commit. The read fixes updates with the most recent version of frequently read data.
