Impala:ClickHouse external table support 01

问题描述

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

// 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);\
  REMOVED_QUERY_OPT_FN(abort_on_default_limit_exceeded, ABORT_ON_DEFAULT_LIMIT_EXCEEDED)\
  QUERY_OPT_FN(abort_on_error, ABORT_ON_ERROR, TQueryOptionLevel::REGULAR)\
  REMOVED_QUERY_OPT_FN(allow_unsupported_formats, ALLOW_UNSUPPORTED_FORMATS)\
  QUERY_OPT_FN(batch_size, BATCH_SIZE, TQueryOptionLevel::DEVELOPMENT)\
  QUERY_OPT_FN(debug_action, DEBUG_ACTION, TQueryOptionLevel::DEVELOPMENT)\
  REMOVED_QUERY_OPT_FN(default_order_by_limit, DEFAULT_ORDER_BY_LIMIT)\
