Todd Lipcon commented on KUDU-1891:
-----------------------------------
I think this is expected - with manual flush, if you try to buffer more than
fits in the configured buffer, you'll get an error. I think switching to
auto_flush_background is probably the right approach here, not sure if this
should be considered a bug.

> Key: KUDU-1891
> URL: https://issues.apache.org/jira/browse/KUDU-1891
> Project: Kudu
> Issue Type: Bug
> Components: python
> Affects Versions: 1.2.0
> Environment: Ubuntu 16.04
> Reporter: Roger
>
> The table had one timestamp column and 19 single precision columns with only
> the timestamp as the primary key.
> The tuples were uploaded in the following way:
> {code}
> table = client.table('new_table')
> session = client.new_session()
> for t in tuples[:100000]:
> session.apply(table.new_insert(t))
> {code}
> Please note that the default flush mode in Python is manual.
> This resulted in the bellow error:
> {code}
