* FEATURE: [stream aggregation](https://docs.victoriametrics.com/stream-aggregation/): add `dedup_interval` option, which allows configuring individual [deduplication intervals](https://docs.victoriametrics.com/stream-aggregation/#deduplication) per each [stream aggregation config](https://docs.victoriametrics.com/stream-aggregation/#stream-aggregation-config).

|
||||
* FEATURE: [stream aggregation](https://docs.victoriametrics.com/stream-aggregation/): add `keep_metric_names` option, which can be set at [stream aggregation config](https://docs.victoriametrics.com/stream-aggregation/#stream-aggregation-config) in order to keep the original metric names in the output aggregated samples instead of using [the default output metric naming scheme](https://docs.victoriametrics.com/stream-aggregation/#output-metric-names).
|
||||
* FEATURE: [stream aggregation](https://docs.victoriametrics.com/stream-aggregation/): align the time of aggregated data flush to the specified aggregation `interval`. For example, if `interval` is set to `1m`, then the aggregated data will be flushed at the end of every minute. The alginment can be disabled by setting `no_align_flush_to_interval: true` option at [stream aggregation config](https://docs.victoriametrics.com/stream-aggregation/#stream-aggregation-config). See [these docs](https://docs.victoriametrics.com/stream-aggregation/#flush-time-alignment) for details.
|
||||
* FEATURE: [stream aggregation](https://docs.victoriametrics.com/stream-aggregation/): add [unique_samples](https://docs.victoriametrics.com/stream-aggregation/#unique_samples) output, which can be used for calculating the number of unique sample values over the given `interval`.

## Ignoring old samples
|
||||
|
||||
By default all the input samples are taken into account during stream aggregation. If samples with old timestamps outside the current [aggregation interval](#stream-aggregation-config)
|
||||
must be ignored, then the following options can be used:
|
||||
|
||||
- To pass `-remoteWrite.streamAggr.ignoreOldSamples` command-line flag to [vmagent](https://docs.victoriametrics.com/vmagent/)
|
||||
or `-streamAggr.ignoreOldSamples` command-line flag to [single-node VictoriaMetrics](https://docs.victoriametrics.com/).
|
||||
This enables ignoring old samples for all the [aggregation configs](#stream-aggregation-config).
|
||||
|
||||
- To set `ignore_old_samples: true` option at the particular [aggregation config](#stream-aggregation-config).
|
||||
This enables ignoring old samples for that particular aggregation config.
|
||||
|
||||
## Flush time alignment
|
||||

||||
By default the time for aggregated data flush is aligned by the `interval` option specified in [aggregate config](#stream-aggregation-config).
