建表语句

CREATE TABLE `qfcx_owner_incoming_alldata` (
  `guid` VARCHAR(36) NOT NULL COMMENT '主键',
  `area_guid` BIGINT NOT NULL COMMENT 'GUID',
  `object_guid` VARCHAR(36) NULL DEFAULT "" COMMENT 'GUID'
	.
    .
    .
    .
    .
 `area_name` VARCHAR(200) NULL DEFAULT "" COMMENT '名称',
) ENGINE=OLAP
UNIQUE KEY(`guid`, `area_guid`)
COMMENT 'OLAP'
DISTRIBUTED BY HASH(`area_guid`) BUCKETS 10
PROPERTIES (
"replication_allocation" = "tag.location.default: 1",
"min_load_replica_num" = "-1",
"is_being_synced" = "false",
"storage_medium" = "hdd",
"storage_format" = "V2",
"inverted_index_storage_format" = "V1",

"enable_single_replica_compaction" = "false",
"group_commit_interval_ms" = "2000",

);

请各位大佬指点~感谢
问题描述:
1、在用flink读取kafka数据然后生成sql,采用jdbc的方法实时更新doris宽表。在sql没有攒批,单条执行的情况下,速度只有每秒100-200左右条的更新。
2、如果换成flink-doris-connector,更新速度会有提升吗,提升有多少?

这种不建议使用jdbc的方式写入,建议直接用flink-doris-connector,这种情况在机器性能不错的话,可以达到几万条/秒的导入
