在这篇文章中的性能调优参数
https://www.oceanbase.com/docs/community-observer-cn-10000000000901379
alter system set _ob_get_gts_ahead_interval=‘1ms’;
alter system set _enable_defensive_check=False;
alter system set _rowsets_enabled=false tenant=t1;
alter system set _enable_newsort=false;
alter system set _trace_control_info=’’ tenant=t1;
alter system set _lcl_op_interval=‘0ms’;
这种参数在官方文档中都没有介绍,请问在哪里能否找到相关介绍?
