Kevin Minder created CALCITE-2322: ------------------------------------- Summary: 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 Attachments: calcite-avatica.patch
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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
