# Grammar for generation of templates of testing objects (tables).
#
# Attention:
# 1. The SQL grammar concurrency_1.yy is highly adjusted to the objects
#    generated by concurrency_1.zz.
#    So please do not modify concurrency_1.zz without adjusting
#    concurrency_1.yy too.
# 2. In concurrency_1.yy we
#    - work on copies of the objects
#    - do not modify the objects
#    created here.
#    Therefore specialities like
#    1. "Special" tables like partitioned, merged, views etc.
#    2. Variation of the storage engine
#    make no sense.
#
# Please read conf/runtime/concurrency_1.yy for more information.
#

# rows => [0, 1, 10, 100 ], might look nice but causes some significant growth
# of data in vardir per server.
# vardir in tmpfs + several parallel RQG runs becomes critical because of the
# limited space in tmpfs. I got a crowd of rare or never seen + not good
# reproducible crashes in various server components. It is till now not clear
# if these crashes are caused by the shortage of free space in tmpfs at all.
# But the likelihood of crashes drops drastic in case there is enough free space.
