RavenDB workshop in NDC, Oslo 4-5th June

Tue, 31 Jan 2012 14:00:24 GMT

The RavenDB workshop is coming to Oslo, Norway in June!

Join us to an intensive RavenDB hands-on workshop just before the great NDC conference starts.

During the first day of this workshop we will get to know RavenDB and its core concepts, get comfortable with its API, learn how to build and customize indexes, and how to correctly model data for use in a document database.

After getting familiar with all the basics in the first day, during the second day we will build on that knowledge to properly grok Map⁄Reduce, Multi–maps and other advanced usages of indexes, learn how to extend RavenDB and the various options of scaling out.

More details on the workshop and the conference can be found here.

New stable build (#615)

Mon, 30 Jan 2012 13:12:04 GMT

The new stable build (#616) introduces many fixes and some new features. See the complete change log below.

The new build is now available for download both from our build server and from nuget. See our download page for more details.

New features:

Incremental backups
Boosting is now supported for querying and indexing
Will automatically handle casts for indexes
Better handling of errors from RavenDB, will not hide them in json text any more
Added the ability to randomly sort values
Easier way to handle dynamic fields, with the new CreateField method.
Added ability to defer database commands to be called on SaveChanges()
Added a way to get the current user from a trigger

BREAKING CHANGES:

Moving the methods that expose indexing behavior to a separate namespace. That way, they don't pollute the query namespace.
Moving to a more strict behavior for existing backups. Backup will FAIL for full backups if destination directories exist.
Removing support for contains from linq API, will generate a big error with explanation why.

Studio:

Can delete all docs in a collection
Fix a bug when typing a not valid query an error dialog was appear.
Show a busy indicator when documents are loading
Can search for documents in the
Supporting api key for the studio
now ctrl+click on any navigation will open in new tab
Add mapped results button to index edit
Fix a NRE. In case of a projection Metadata can be null, and ToJson assumes Metadata is always not null.
Fix spatial query not sending parameters
Add the current URI to the error message
Store the URL of the request that is faulted.
Convert SecurityException to ServerNotFound exception.
Logs are now sorted by date descending
Ctrl+Click on the Studio will open in a new tab.
Better errors in the studio.

Client API:

Implement DeleteByIndexAsync
Optimizations - don't create copy of the strings we send to the server, send them directly
Added IDatabaseCommands.Head() method to retrieve a document's metadata (JsonDocumentMetadata).
Fix a bug where nested aggressively caching operation wasn't allowed
Adding better error handling for when we can't parse json from the server
Properly translate a custom identity property in a base type
Filter out OR, AND etc that might create issues parsing during Search
Will automatically handle _Range postfix if the values are numeric and there isn't a _range postfix for range queries
fixed anonymous arrays in expression string builder
Moved to Reading Json directly, rather than the string, better error handling that way
Avoid calling TryEnlist if we don't have to, will avoid full trust issues
Better support for handling equality of guids to strings
Fixing an issue where multi load would optimize itself on the wire and will give different results when running remote vs. local

Indexing & Searching:

Adding a way to access the metadata in strongly typed indexes. MetadataFor().
Fixing #410 - reserved words in indexes
Fixed aliases in projection using Linq chained method syntax
Supporting boosting when using Linq Search API
Support boosting on search phrases
Better error handling when the facet document is not found
Adding support for boosting a value during indexing
Allow to set boost level over the entire document
We can now specify boosting on a per field basis
Fixed an issue where some Enumerable extension methods couldn't be bound
Fixing an issue where we doubly handled reverse
Can generate complex indexes with the appropriate lambda casting
Adding a method that allows us to access the entity as a document. AsDocument().
Fixing an issue with OrderBy followed by a Search
Add a helper method to dynamically store fields in an index, without explicitly using the Lucene.Net.Document.Field class.
Fixing an issue where we have an issue with multiplication of decimals would generate an error
Fixing an issue where we weren't comparing to null properly
Fixing an issue where very complex dynamic query wouldn't hash properly

Mvc Integration:

Fixing an issue where we would generate a recursive check for ajax requests

Server:

Can get the database size using: GET /database/size
Reduce the size that we use for transactional logging
Reduced the size that the db would grow by default, smaller db dir sizes
Allow customizing the index storage path and logs path for each tenant
Better way to handle disposal of database resources when running in IIS.
Safe handling of errors during disposal
Handle the scenario where an idle database cannot be properly disposed in a nicer fashion
Fix typo: Non-Authoritive-Information to Non-Authoritative-Information
Support both "~\" and "~/" for configuration of relative paths.
Better handling of concurrency problems when shutting down the server
Added a way to configure esent circular log
Fixing things so we can register the nlog config properly for http endpoint in IIS
Support copying indexes on incremental backups
Don't send an etag for the case where the Studio.xap cannot be found (force the browser to always recheck)
Ensure that we can't get into duplicate index errors because of concurrency issues
Allow parsing of more free form [[ ]] elements
Fixing an issue where we couldn't read an inflight transaction document using Munin
Allow to define tokens that have read / write permissions per db, not globally
Better handling of disposal concerns when running inside IIS
Better logging for start/end on IIS
Add support for env variables in paths
Better output for when we are running in memory
Fixing incremental backups support
Can now support administrator in OAuth
Auth bundle now support admin users

Licensing:

Allow to specify license string using Raven/License
Allow to specify license path using Raven/LicensePath
Won't do multiple license checks when running using OEM
Don't run licensing for each database on the server, run it only once
Avoid publishing presence again if we get notification within the publish limit

Replication:

Will not replication recovery information attachments
Added a way to explicitly avoid replication for certain documents / documents
Adding option to control transitive replication (default is OFF)
Fixing an issue where deleting a document with the replication bundle active wouldn't physically remove it from the index

Smuggler:

Adding smuggler option to skip pushing indexes

Free session: RavenDB indexes explained, London Feb 28th

Afraid of Map/Reduce?

Itamar Syn-Hershko will be giving a talk in Tuesday Februrary 28th, explaining RavenDB indexes and how to work with them correctly. In this session we will walk through the RavenDB indexing process, grok it, and while at it master techniques with frightful names like Map/Reduce, MultiMap, Live Projections, Full text search, Boosting and more.

The session is free for all, and will be held at the Skills Matter eXchange facilities in London.

Here is a short list of the important things that are new:

A brand new look
Comprehensive documentation
Community-driven Knowledge Base - add content, comment on others' articles, browse by tags
Commenting on content (documentation, news items, KB articles)
News feed you can subscribe to to always stay up-to-date
New events page
