# Tenzir Node v4.30.1

## 🚀 Features

### Move rebatching into the `importer` actor

Mar 19, 2025 · [@dominiklohmann](https://github.com/dominiklohmann) · [#5056](https://github.com/tenzir/tenzir/pull/5056)

The import buffer timeout is now configurable via the `tenzir.import-buffer-timeout` option. The option defaults to 1 second, and controls how long the `import` operator buffers events for batching before forwarding them. Set the option to `0s` to enable an unbuffered mode with minimal latency, or to a higher value to increase performance.

### Move rebatching into the `importer` actor

Mar 19, 2025 · [@dominiklohmann](https://github.com/dominiklohmann) · [#5056](https://github.com/tenzir/tenzir/pull/5056)

The default value for the `tenzir.active-partition-timeout` option increased from 30s to 5min. The option controls how long the `import` operators waits until flushing events to disk. In the past, this value was set so low because the `export` operator was only able to access already flushed events. This is no longer the case, removing the need for the low timeout. Note that the `import` operator always immediately flushes events after a pipeline with `import` completes, or when the node shuts down.
