# Logging
Druid nodes will emit logs that are useful for debugging to the console. Druid nodes also emit periodic metrics about their state. For more about metrics, see [Configuration](../configuration/index.html#enabling-metrics). Metric logs are printed to the console by default, and can be disabled with `-Ddruid.emitter.logging.logLevel=debug`.

# Deep Storage
Deep storage is where segments are stored. It is a storage mechanism that Druid does not provide. This deep storage infrastructure defines the level of durability of your data, as long as Druid nodes can see this storage infrastructure and get at the segments stored on it, you will not lose data no matter how many Druid nodes you lose. If segments disappear from this storage layer, then you will lose whatever data those segments represented.

The plumber handles generated segments both while they are being generated and when they are "done". This is also technically a pluggable interface and there are multiple implementations. However, plumbers handle numerous complex details, and therefore an advanced understanding of Druid is recommended before implementing your own.

Druid aggregators based on [datasketches](http://datasketches.github.io/) library. Sketches are data structures implementing approximate streaming mergeable algorithms. Sketches can be ingested from the outside of Druid or built from raw data at ingestion time. Sketches can be stored in Druid segments as additive metrics.

# DataSketches HLL Sketch module
This module provides Druid aggregators for distinct counting based on HLL sketch from [datasketches](http://datasketches.github.io/) library. At ingestion time, this aggregator creates the HLL sketch objects to be stored in Druid segments. At query time, sketches are read and merged together. In the end, by default, you receive the estimate of the number of distinct values presented to the sketch. Also, you can use post aggregator to produce a union of sketch columns in the same row.

# DataSketches Quantiles Sketch module
This module provides Druid aggregators based on numeric quantiles DoublesSketch from [datasketches](http://datasketches.github.io/) library. Quantiles sketch is a mergeable streaming algorithm to estimate the distribution of values, and approximately answer queries about the rank of a value, probability mass function of the distribution (PMF) or histogram, cummulative distribution function (CDF), and quantiles (median, min, max, 95th percentile and such). See [Quantiles Sketch Overview](https://datasketches.github.io/docs/Quantiles/QuantilesOverview.html).

# Router Node
You should only ever need the router node if you have a Druid cluster well into the terabyte range. The router node can be used to route queries to different broker nodes. By default, the broker routes queries based on how [Rules](../operations/rule-configuration.html) are set up. For example, if 1 month of recent data is loaded into a `hot` cluster, queries that fall within the recent month can be routed to a dedicated set of brokers. Queries outside this range are routed to another set of brokers. This set up provides query isolation such that queries for more important data are not impacted by queries for less important data.

TopN queries return a sorted set of results for the values in a given dimension according to some criteria. Conceptually, they can be thought of as an approximate [GroupByQuery](../querying/groupbyquery.html) over a single dimension with an [Ordering](../querying/limitspec.html) spec. TopNs are much faster and resource efficient than GroupBys for this use case.
