Kevin Minder commented on CALCITE-2322:
---------------------------------------
An additional parameter for fetch_bytes or buffer_size seems like a useful
addition. The interplay between them however may become confusing. What would
the behavior be if the bytes required to supply fetch_size rows exceeds the
byte could suppled by fetch_bytes?
> Add fetch size support to connection url and JDBC statement

> Key: CALCITE-2322
> URL: https://issues.apache.org/jira/browse/CALCITE-2322
> Project: Calcite
> Issue Type: Improvement
> Components: core
> Affects Versions: 1.11.0
> Reporter: Kevin Minder
> Assignee: Julian Hyde
> Priority: Major
>
> Currently the remote driver defaults to hard coded fetch size of 100 rows.
> When a connection is operating in HTTP mode having such a small fetch size
> can add enormous overhead. This is especially true if TLS connections are
> used and made worse if each connection flows throw multiple proxies.
> Consider that 100K rows returned 100 rows at a time will make 1K HTTP POST
> requests. One might say that nobody should ever do that but some tools like
> Spotfire may end up doing this.
