Dear Doris，
我部署了一台单机doris，库中有一张60G的数据表，添加索引后达到了96G，但在添加索引后，执行查询时，报了SQL 错误 [1105]
[HY000]: RpcException, msg: io.grpc.StatusRuntimeException: UNAVAILABLE:
Network closed for unknown reason
然后BE宕掉，重启BE后，再次查询依然宕掉，请问是什么原因呢？如果还需要其他配置，还请提出，期待你的回复。
建表语句如下
CREATE TABLE `kktlog_syncdata` (
`topicname` varchar(500) NULL,
`jsonstr` text NULL,
`data_day` date NULL,
`data_time` datetime NULL DEFAULT CURRENT_TIMESTAMP,
INDEX idx_bitmap_jsonstr (`jsonstr`) USING BITMAP COMMENT ''
) ENGINE=OLAP
DUPLICATE KEY(`topicname`)
COMMENT 'instance ikt data'
DISTRIBUTED BY HASH(`topicname`) BUCKETS 10
PROPERTIES (
"replication_allocation" = "tag.location.default: 1",
"is_being_synced" = "false",
"storage_format" = "V2",
"light_schema_change" = "true",
"disable_auto_compaction" = "false",
"enable_single_replica_compaction" = "false"
);
