# INSERT
#
# INSERT and commit new rows, using the constants "40" for most values.
# For each new transaction, the constant is increased by 1.
#
# This test runs a number of consecutive transactions to generate high 
# concurrency:
#
# Tx 1:
#  - multi-statemement insert, inserting first positive then negative number (0-sum).
#
# Tx 2:
#  - insert multiple rows using a single statement.
#
# Tx 3:
#  - INSERT IGNORE using both known duplicate values and non-duplicates.
#
# Net effect: 6 more rows
#
# In this test we need some kind of valid unique integer value for the columns
# with unique indexes.
#
# Alternatively: 
#  - Set unique value as 0 and rollback if ERR_DUP_KEY (see 
#    check_error_rollback.inc), then make sure to UPDATE where unique value is 0
#    in other tests.
#  - OR: insert NULL (requires special handling when calculating row sums in 
#    other tests).
#  - OR: skip unique indexes entirely (except `pk`) (remove from t1 in init).
#
# Using CONNECTION_ID (swithcing sign and doing +/- 3) as unique value, meaning 
# that some of the INSERTs will fail with duplicate key until this is high 
# enough (should not take long with a relatively high number of threads and some
# duration, given that the number of initial rows is relatively low, ~1000). 
# Let's just say this is a warm-up period.
#
# Alternatively, add some random integer to the value or use UNIX_TIMESTAMP()
# (the latter requires that some care is taken in subsequent updates etc. For
# example, simply doubling the value will cause overflow/truncation).
# 
# No need to ROLLBACK if all statements in a transaction by themselves are
# consistent.
