# This grammar is designed to generate a workload suitable for testing the Drizzle
19
# transaction_log. It is intended for use with --threads=1 and with the DrizzleTransactionLog Validator
20
# Using the Validator requires that we have a validation server running somewhere so we
21
# can try to replicate from SQL generated from the transaction_log (via drizzled/message/transaction_reader
23
# This is still a work in progress and is likely to change.
24
# We are generating a fair number of invalid queries and we could tighten things up, however,
25
# we have found a number of bugs with this grammar as it currently exists.
