* Various documentation updates.
1) Split out "data management" from "ingestion". Break it into thematic pages.
2) Move "SQL-based ingestion" into the Ingestion category. Adjust content so
all conceptual content is in concepts.md and all syntax content is in reference.md.
Shorten the known issues page to the most interesting ones.
3) Add SQL-based ingestion to the ingestion method comparison page. Remove the
index task, since index_parallel is just as good when maxNumConcurrentSubTasks: 1.
4) Rename various mentions of "Druid console" to "web console".
5) Add additional information to ingestion/partitioning.md.
6) Remove a mention of Tranquility.
7) Remove a note about upgrading to Druid 0.10.1.
8) Remove no-longer-relevant task types from ingestion/tasks.md.
9) Move ingestion/native-batch-firehose.md to the hidden section. It was previously deprecated.
10) Move ingestion/native-batch-simple-task.md to the hidden section. It is still linked in some
places, but it isn't very useful compared to index_parallel, so it shouldn't take up space
in the sidebar.
11) Make all br tags self-closing.
12) Certain other cosmetic changes.
13) Update to node-sass 7.
* make travis use node12 for docs

Apache Druid stores data [partitioned by time chunk](../design/architecture.md#datasources-and-segments) in immutable
|
|
files called [segments](../design/segments.md). Data management operations involving replacing, or deleting,
|
|
these segments include:
|
|
|
|
- [Updates](update.md) to existing data.
|
|
- [Deletion](delete.md) of existing data.
|
|
- [Schema changes](schema-changes.md) for new and existing data.
|
|
- [Compaction](compaction.md) and [automatic compaction](automatic-compaction.md), which reindex existing data to
|
|
optimize storage footprint and performance.
