Subject: pgsql: Change the default value of the streaming option to 'parallel'.
Date: Mon, 28 Oct 2024 03:25:04 +0000
Message-ID: <E1t5GNM-002mZB-Hu@gemulon.postgresql.org> (raw)
Change the default value of the streaming option to 'parallel'.
Previously the default value of streaming option for a subscription was
'off'. The parallel option indicates that the changes in large
transactions (greater than logical_decoding_work_mem) are to be applied
directly via one of the parallel apply workers, if available.
The parallel mode was introduced in 16, but we refrain from enabling it by
default to avoid seeing any unpleasant behavior in the existing
applications. However we haven't found any such report yet, so this is a
good time to enable it by default.
