Impala ClickHouse 建表工作已经接近尾声，前瞻一下
https://github.com/apache/impala/blob/master/be/src/service/query-options.h#L53
Impala 也有这么愚蠢的代码，我就放心改了
代码语言：javascript复制// Macro to help generate functions that use or manipulate query options.
// If the DCHECK is hit then handle the missing query option below and update
// the DCHECK.
// Specifically, the DCHECK will make sure that the number of elements in
// the map _TImpalaQueryOptions_VALUES_TO_NAMES automatically generated in
// ImpalaService_types.cpp is equal to the largest integer associated with an
// option in the enum TImpalaQueryOptions (defined in ImpalaService.thrift)
// plus one. Thus, the second argument to the DCHECK has to be updated every
// time we add or remove a query option to/from the enum TImpalaQueryOptions.
#define QUERY_OPTS_TABLE
DCHECK_EQ(_TImpalaQueryOptions_VALUES_TO_NAMES.size(),
TImpalaQueryOptions::LOCK_MAX_WAIT_TIME_S 1);
