Bumps @clickhouse/client from 0.2.10 to 0.3.0.

Changelog

Sourced from @​clickhouse/client's changelog.

0.3.0 (Node.js only)

This release primarily focuses on improving the Keep-Alive mechanism's reliability on the client side.

New features

• Idle sockets timeout rework; now, the client attaches internal timers to idling sockets, and forcefully removes them from the pool if it considers that a particular socket is idling for too long. The intention of this additional sockets housekeeping is to eliminate "Socket hang-up" errors that could previously still occur on certain configurations. Now, the client does not rely on KeepAlive agent when it comes to removing the idling sockets; in most cases, the server will not close the socket before the client does.

• There is a new keep_alive.idle_socket_ttl configuration parameter. The default value is 2500 (milliseconds), which is considered to be safe, as ClickHouse versions prior to 23.11 had keep_alive_timeout set to 3 seconds by default, and keep_alive.idle_socket_ttl is supposed to be slightly less than that to allow the client to remove the sockets that are about to expire before the server does so.

• Logging improvements: more internal logs on failing requests; all client methods except ping will log an error on failure now. A failed ping will log a warning, since the underlying error is returned as a part of its result. Client logging still needs to be enabled explicitly by specifying the desired log.level config option, as the log level is OFF by default. Currently, the client logs the following events, depending on the selected log.level value:

  • TRACE - low-level information about the Keep-Alive sockets lifecycle.
  • DEBUG - response information (without authorization headers and host info).
  • INFO - still mostly unused, will print the current log level when the client is initialized.
  • WARN - non-fatal errors; failed ping request is logged as a warning, as the underlying error is included in the returned result.
  • ERROR - fatal errors from query/insert/exec/command methods, such as a failed request.

Breaking changes

• keep_alive.retry_on_expired_socket and keep_alive.socket_ttl configuration parameters are removed.
• The max_open_connections configuration parameter is now 10 by default, as we should not rely on the KeepAlive agent's defaults.
• Fixed the default request_timeout configuration value (now it is correctly set to 30_000, previously 300_000 (milliseconds)).

Bug fixes

• Fixed a bug with Ping that could lead to an unhandled "Socket hang-up" propagation.
• Ensure proper Connection header value considering Keep-Alive settings. If Keep-Alive is disabled, its value is now forced to "close".
