# Deadlock in conjunction with the innodb change buffering.
|
|
|
|
# When innodb change buffering kicks in, i.e secondary non-unique index
|
|
# does not fit into the bufferpool, then, on Windows, innodb
|
|
# background threads could deadlock whenever index page is
|
|
# read, and the page needs load/merge change buffer.
|
|
# The test tries to reproduce this situation, by creating index
|
|
# that does not fit into bufferpool, and doing a large update.
