# Validate that huge GTID_EXECUTED values are properly handled on distributed
|
|
# recovery, transactions certification and certification garbage collection
|
|
# procedure.
|
|
#
|
|
# Test:
|
|
# 0. The test requires two servers: M1 and M2.
|
|
# 1. Generate a huge GTID_EXECUTED with 70043 characters length. It will be
|
|
# like:
|
|
# aaaaaaaa-aaaa-aaaa-aaaa-aaaaaaaaaaaa:10000:10002:...:120000
|
|
# 2. Set huge GTID_EXECUTED on both M1 and M2.
|
|
# 3. Bootstrap start on M2. The huge GTID_EXECUTED will be exchanged on
|
|
# distributed recovery process on M1.
|
|
# 4. Execute some transactions and check that nothing bad happens. Validate
|
|
# that data is delivered to both members.
|
|
# 5. Wait for stable set propagation and certification info garbage collection.
|
|
# 6. Check that stable set is properly updated after stable set propagation and
|
|
# certification info garbage collection.
|
|
# 7. Clean up.
