AsterixDB supports various storage and indexing options:

• [Managed datasets]({{ site.DOCS_BASE_URL }}/{{ site.STABLE_VERSION }}/aql/primer.html), internal LSM-based storage
• [External datasets]({{ site.DOCS_BASE_URL }}/{{ site.STABLE_VERSION }}/aql/externaldata.html), e.g., data on HDFS
• [Secondary indexes]({{ site.DOCS_BASE_URL }}/{{ site.STABLE_VERSION }}/aql/primer.html), for both storage options.
