It would be nice to add the transfer latency to the log statements in the defer. That way we can dig into the source of unexpectedly high/low latency.
Done.
Previously, we added support for connection migration in cockroachdb#76805. This commit adds a new `proxy.conn_migration.attempted.latency` metric that tracks latency for attempted connection migrations. Having this metric would be beneficial as we can now know how long users were blocked during connection migrations. Release justification: Low-risk metric-only change within sqlproxy.

This commit adds a new proxy.conn_migration.transfer_response.message_size metric that will track the distribution of the transfer response message size. This will be used to tune a value for the SQL cluster setting: sql.session_transfer.max_session_size. Release justification: Low-risk metric-only change within sqlproxy. Release note: None

ccl/sqlproxyccl: add metric that measures connection migration latency
Previously, we added support for connection migration in #76805. This commit
adds a new
proxy.conn_migration.attempted.latencymetric that tracks latencyfor attempted connection migrations. Having this metric would be beneficial
as we can now know how long users were blocked during connection migrations.
Release justification: Low-risk metric-only change within sqlproxy.

ccl/sqlproxyccl: add metric that records the transfer response message size
Informs #76000, and follow up to #76805.
This commit adds a new proxy.conn_migration.transfer_response.message_size
metric that will track the distribution of the transfer response message size.
This will be used to tune a value for the SQL cluster setting:
sql.session_transfer.max_session_size.
Release justification: Low-risk metric-only change within sqlproxy.
Release note: None
