[kano5252]

It seems 1.2 Oracle r2dbc doesn't support defaultRowPrefetch ConnectionPropety

here's the issue: Oracle version: 19c spring boot r2dbc 3.2.5 I have a table (80k rows ), select all data using R2dbcTemplate which needs nearly 63 seconds, on DB visualizer Tool after set JDBC Fetch size to 5000, it only needs 0.6s, As far as I know, JDBC fetch Size is defaultRowPrefetch in Oracle, but seems it's not supported yet, please advise how to set it.
