Will delete/update affect the schema?
What's the meaning of 'schema' here?

yes, this config works. thanks.
My sql is a very big sql?? so 60 concurrent queries does not work.

: Re: can CarbonThriftServer configure the max number of submit
Yes, it is really a bug. You can raise a jira for this problem.
I tried the following queries and they are OK. Hope it will help you bypass the
bug.
```
create table IF NOT EXISTS test.Account(CAP_CHARGE Array,CAP_CR_INT
Array) partitioned by (current_dt DATE) STORED BY 'carbondata'
```
```

Spark dataframe does not have char/varchar datatype, it only has string type.
Suppose we are saving spark dataframe to carbonata, if the length of value is
longer than 32000 and its datatype is string, how will carbondata know to store
it as longstring?
In my opinion, a property to indicate whi
+1 for solution 2
I think it's ok to truncate the string value to N if its length is longer
than N, it's acceptable.

In traditional RDBMS, varchar(N) means the value contains at least N
characters, at the DBMS will truncate the value if its length is longer than N.
Will we implement like this too? Truncate the string value to N if its length
is longer than N?
Maybe you can try `hive.server2.thrift.max.worker.threads` and set a smaller
value for it.
You can configure it in hive-site.xml or pass the configuration through
??hiveconf when you start the thrift-server.
At last, you need to find out the root cause of the failed sqls. 60 concurrent
queries

Hi Dev,
Currently DataMap while pruning is considering SegmentProperties from the
0th block of Segment DataMap.
It is not correct as post schema restructure if the table is updated
(*Update/Delete record*) then within the segment, all the block will not
have symmetric schema.
To support schema

hi dev,
I start CarbonThriftServer, then use beeline to connect it. But when I submit
60 sqls at the same time, all task failed.
So I want to know, is there a configure to restrict the max number of running
sql in carbonthriftserver, for example, if the number of running sql is larger
than this
12 matches
