For the realtime dataSources, it's recommended to set `skipOffsetFromLatest` to some sufficiently large values to avoid frequent compact task failures.

This compaction task merges _all segments_ of the interval `2017-01-01/2018-01-01` into a _single segment_.
To merge each day's worth of data into a separate segment, you can submit multiple `compact` tasks, one for each day. They will run in parallel.
This compaction task reads _all segments_ of the interval `2017-01-01/2018-01-01` and results in new segments.
Note that intervals of the input segments are merged into a single interval of `2017-01-01/2018-01-01` no matter what the segmentGranularity was.
To controll the number of result segments, you can set `targetPartitionSize` or `numShards`. See [indexTuningConfig](#tuningconfig) for more details.
To merge each day's worth of data into separate segments, you can submit multiple `compact` tasks, one for each day. They will run in parallel.

A compaction task internally generates an `index` task spec for performing compaction work with some fixed parameters.
For example, its `firehose` is always the [ingestSegmentSpec](./firehose.html), and `dimensionsSpec` and `metricsSpec`
