# Test case to verify that concurrent transactions with intersecting
# write set, the same unique key, do conflict.
#
# Scenario 8.1: WL#6834
#
# T1: WS={t1.c1=1,t1.c2=2}
#
# T2: WS={t1.c1=3,t1.c2=2}
#
# Outcome: T1 must abort, T2 must commit.
#
# Full details on WL#6834 QA notes.
#
# Test:
# 0. The test requires two servers: M1 and M2.
# 1. With both members ONLINE. Create a table on M1.
# 2. Test the following two scenarios by calling
# gr_parallel_local_and_remote_transactions.inc.
# Scenario 1: UNIQUE NOT NULL KEY, conflicting case (1,2) vs (3, 2).
# Scenario 2: UNIQUE NOT NULL KEY, non-conflicting case (5,6) vs (7,8).
# 3. Check the data sanity after the above two scenarios are executed.
# 4. Clean up.
