Benchmark:
[https://github.com/cmu-db/benchbase/tree/main/src/main/java/com/oltpbenchmark/benchmarks/tpch]
h1. Setup
* 1 Ignite 3 server node, raft.fsync = false
* TPC-H with scale factor = 0.1
h1. Steps
# Start an Ignite 3 node
# Run benchbase with {{-s 1 --create=true --load=true --execute=false}} to
preload data
# Observe via the benchbase log that the data was successfully loaded
# Run {{benchbase with -s 1 --create=false --load=false --execute=true}} to
run the benchmark
h1. Expected result
The benchmark finishes after warmup + duration time
h1. Actual result
The benchmark hangs on Q21 query:
