Julian Hyde commented on CALCITE-2322: -------------------------------------- Same would go for other Statement properties (escapeProcessing, fetchDirection, maxRows, poolable, queryTimeout) and Connection properties (autoCommit, catalog, holdability, readOnly, transactionIsolation) we might add in the future. We already have a "schema" connection property, which maps to Connection.setSchema(String). > 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
