We just noticed a nice feedback from a mORMot user. Vojko Cendak commented the well-known DataSnap analysis based on Speed & Stability tests blog article written by Roberto some months years (!) ago. It is not meant to be the final word, perhaps there was some tuning possible for RTC (which is […]

Performance issue in NextGen ARC model - much better now
2015-09-14.
Back in 2013, I found out an implementation weakness in the implementation
of ARC weak references in the RTL.
A giant lock
was freezing all threads and cores, so would decrease a lot the performance
abilities of any ARC application, especially in multi thread.
I just investigated that things are now better.

Delphi 10 = DX Seattle is out, mORMot supports it
2015-08-31. Pascal Programming
We expected Delphi XE9, and now we have Rad Studio 10 Seattle, with Delphi renamed as Delphi 10 Seattle, or simply DX. No big news for the Delphi compiler itself (we are still waiting for Linux server support), but a lot of FireMonkey updates, Windows 10 compatibility enhancements, enhancements to […]

Introducing Delphinus PackageManager
2015-08-24. Pascal Programming
You may have missed the news. So I relay here the information from Delphinus PackageManager blog article. Delphinus is a new Package Manager, which runs on Delphi XE and newer, directly from within your IDE. It is GitHub-based, and fairly easy to add a reference to. Of course, I tried to add mORMot […]

"SQL and NoSQL", not "SQL vs NoSQL"
2015-08-23. Open Source › mORMot Framework
You know certainly that our mORMot Open Source framework is an ORM,
i.e. mapping objects to a relational / SQL database (Object
Relational Mapping).
You may have followed also that it is able to connect to a
NoSQL database, like MongoDB, and
that the objects are then mapped via an ODM (Object
Document Mapping) - the original SQL SELECT are even
translated on the fly to MongoDB queries.
But thanks to mORMot, it is not "SQL vs NoSQL" - but
"SQL and NoSQL".
You are not required to make an exclusive choice.
You can share best of both worlds, depending on your application needs.
In fact, the framework is able to add NoSQL features to a regular relational / SQL database, by storing JSON documents in TEXT columns.
In your end-user code, you just define a variant field in
the ORM, and store a
TDocVariant document within.
We also added some dedicated functions at SQL level, so that
SQLite3 could be used as embedded fast engine, and provide
advanced WHERE clauses on this JSON content.

Breaking Change in mORMot WebSockets binary protocol
2015-08-15. Open Source › mORMot Framework
Among all its means of transmission, our mORMot framework
features
WebSockets, allowing bidirectional communications, and interface-based
callbacks for real time notification of SOA events.
After several months of use in production, we identified some needed changes
for this just emerged feature.
We committed
today a breaking change of the data layout used for our proprietary
WebSockets binary protocol.
From our tests, it would increase the performance and decrease the resource
consumption, especially in case of high number of messages.

New blog about mORMot
2015-07-14. Open Source › mORMot Framework
An enthusiastic mORMot user, named willo in the forum, just started a blog about his experiments with our framework.
The information there is clear, simple, and right to the point.
If you are a little lost in our huge documentation, it is a good place to
start!

Faster String process using SSE 4.2 Text Processing Instructions STTNI
2015-06-30. Open Source › mORMot Framework
A lot of our code, and probably yours, is highly relying on text process. In our mORMot framework, most of its features use JSON text, encoded as UTF-8. Profiling shows that a lot of time is spent computing the end of a text buffer, or comparing text content. You may know that In its SSE4.2 feature […]
