@clickhouse/client 0.1.0

npm / @clickhouse/client / 0.1.0 source ↗

Breaking changes

• connect_timeout client setting is removed, as it was unused in the code.

New features

• command method is introduced as an alternative to exec. command does not expect user to consume the response stream, and it is destroyed immediately. Essentially, this is a shortcut to exec that destroys the stream under the hood. Consider using command instead of exec for DDLs and other custom commands which do not provide any valuable output.

Example:

// incorrect: stream is not consumed and not destroyed, request will be timed out eventually
await client.exec('CREATE TABLE foo (id String) ENGINE Memory')

// correct: stream does not contain any information and just destroyed
const { stream } = await client.exec('CREATE TABLE foo (id String) ENGINE Memory')
stream.destroy()

// correct: same as exec + stream.destroy()
await client.command('CREATE TABLE foo (id String) ENGINE Memory')

Bug fixes

• Fixed delays on subsequent requests after calling insert that happened due to unclosed stream instance when using low number of max_open_connections. See #161 for more details.
• Request timeouts internal logic rework (see #168)
