Support to get tables in materialized view when collecting table in plan
table scehma as fllowing:
create materialized view mv1
BUILD IMMEDIATE REFRESH COMPLETE ON MANUAL
DISTRIBUTED BY RANDOM BUCKETS 1
PROPERTIES ('replication_num' = '1')
as
select
t1.c1,
t3.c2
from
table1 t1
inner join table3 t3 on t1.c1 = t3.c2
if get table from the plan as follwoing, we can get [table1, table3, table2], the mv1 is expanded to get base tables;
SELECT
mv1.*,
uuid()
FROM
mv1 LEFT SEMI
JOIN table2 ON mv1.c1 = table2.c1
WHERE
mv1.c1 IN (
SELECT
c1
FROM
table2
)
OR mv1.c1 < 10
Fix Reach limit of connections error
in fe.conf , arrow_flight_token_cache_size is mandatory less than qe_max_connection/2. arrow flight sql is a stateless protocol, connection is usually not actively disconnected, bearer token is evict from the cache will unregister ConnectContext.

The reason is misuse of cosn's file sytem. according to cosn's doc, its fs.cosn.impl should be org.apache.hadoop.fs.CosFileSystem

get_query_ctx(hold query ctx map lock) ---> QueryCtx ---> runtime statistics mgr --->
runtime statistics mgr ---> allocate block memory ---> cancel query
memtracker will try to cancel query when memory is not available during allocator.
BUT the allocator is a foundermental API, if it call the upper API it may deadlock.
Should not call any API during allocator.
