# 
# Simple test of the serial event log for single INSERT/DELETE statements
# 
# We create a table and insert some records
# into it then delete a record. 
# 
# We then use the transaction_reader in drizzled/message/ to read the events.

# are specified in a DELETE statement.  In the absence
# of triggers, this equates to a TRUNCATE TABLE statement, 
# and this is what should be written to the transaction log, 
# not multiple DeleteRecord events.
#
# However, right now this optimization does not occur. We
# write individual DeleteRecord message to the log.  We will
# optimize this away once TableShare has been refactored
