DocumentDB Indexing Policies–Portal Choices I have been using Azure DocumentDB for a good while now and think it is a very interesting service. The fact that all attributes by default are able to be indexed with no real sign of performance impact on insertion speaks volumes for the team in Redmond. The Azure DocumentDB Data Migration Tool is an open source solution that imports data to DocumentDB, Azure's NoSQL document database service. The latest release of the tool opens up not only additional import sources, but also the ability to apply an indexing policy to DocumentDB collections during import. id is implicitly treated as the document's primary key - in which, id will always be indexed with uniqueness enforced. _ts is an epoch timestamp of when a document was last written (create or replace), and will also always be indexed. This property will be explicitly noted within the index policy.

We can choose different indexing policies, but for most applications the default indexing policy will be the best choice between performance and storage

22 Dec 2015 You can also choose a pricing tier and indexing policy other than the default options.

The default index Modifying the indexing policy. A container's indexing policy can be updated at any time by using the Azure portal or one of the supported SDKs. An update to the indexing policy triggers a transformation from the old index to the new one, which is performed online and in place (so no additional storage space is consumed during the operation). Every DocumentDB collection has an associated “Indexing policy” to control aspects of index management including index storage overhead, write and query throughput and query consistency. The indexing policy associated with a DocumentDB collection will automatically index all properties of all documents in addition to providing consistent query. In automatic indexing, documents can be explicitly excluded from indexing using RequestOptions. In manual indexing, documents can be explicitly included. getExcludedPaths() Gets the paths that are not indexed. getIncludedPaths() Gets the paths that are chosen to be indexed by the user. getIndexingMode() Gets the indexing mode (consistent or lazy).

17 Feb 2019 By default, the Azure Cosmos DB data is indexed. Azure applies its default indexing policy while creating a collection. However, a user can set

Relational SQL database which is designed for working with sets, DocumentDB, on the other hand, is for schemaless unstructured data, optimized for working by individual documents and designed for scale. You should never do a full scan and read all documents as it would not scale. Indexing Policy Tip #3: Specify range index path type for all paths used in range queries DocumentDB currently supports two index path types: Hash and Range. Choosing an index path type of Hash enables efficient equality queries. Choosing an index type of Range enables range queries (using >, <, >=, <=). Procedures for Scanning and Indexing. Document is received by office- Correct employee processes the request. Check for information to redact. Once the document has been processed. The employee places the document in the bins by last name over by the scanning and indexing station. Every DocumentDB collection has an associated “Indexing policy” to control aspects of index management including index storage overhead, write and query throughput and query consistency. The indexing policy associated with a DocumentDB collection will automatically index all properties of all documents in addition to providing consistent query. DocumentDB indexing policies. While many customers are happy to let Azure DocumentDB automatically handle all aspects of indexing, DocumentDB also supports specifying a custom indexing policy for collections during creation. Indexing policies in DocumentDB are more flexible and powerful than secondary indexes offered in other database platforms, because they let you design and customize the DocumentDB now supports online index transformations. With this release, you can create and modify the indexing policy configuration of your DocumentDB collections. The index transformations are applied online/in place, so you can continue to read, write and query while the indexing is in progress.
