benchmark 5.0 压测 tbase 报错 about tbase HOT 1 OPEN

1、TPCC推荐配置：
如三台机器16core + 64G，则tpcc的参数配置可以是
conn=jdbc:postgresql://192.168.0.2:11379,102.168.0.3:11381,192.168.0.4:11379/global？loadBalanceHosts=true&oracle_compile=true
warehouses=500
loadWorkers=32
terminals=96

内核参数：
persistent_datanode_connections = 'on'
enable_material = 'off'
enable_bitmapscan = 'off'
max_wal_size = '12GB'
shared_buffers = '16GB'
checkpoint_timeout = '600'
min_wal_size = '4GB'
pooler_scale_factor = '64'
archive_status_control = 'continue'
maintenance_work_mem = '4GB'
effective_cache_size = '50GB'
max_parallel_workers_per_gather = '0'
max_pool_size = '65535'
work_mem = '8MB'
wal_keep_segments = '4096'

2、针对你说的 select * from pg_prepared_xacts; 查询到的是2PC事务中处于prepare阶段的事务，在分布式系统中属于正常会自动结束，如果某个事务长时间不结束可能存在2PC残留的情况，可参考下面的材料进行人工自动清理：
