+- STT_TRIGGER: specifies the number of file merges triggered by flushed files. The default is 8, ranging from 1 to 16. For high-frequency scenarios with few tables, it is recommended to use the default configuration or a smaller value for this parameter; For multi-table low-frequency scenarios, it is recommended to configure this parameter with a larger value.
 - TABLE_PREFIX：The prefix length in the table name that is ignored when distributing table to vnode based on table name.
 - TABLE_SUFFIX：The suffix length in the table name that is ignored when distributing table to vnode based on table name.
 - TSDB_PAGESIZE: The page size of the data storage engine in a vnode. The unit is KB. The default is 4 KB. The range is 1 to 16384, that is, 1 KB to 16 MB.
