Editor's Notes
- Short introduction + about myself
- Short agenda
- general microservices stuff
- Local Data(Structured Data) * Data model explicitly determines the structure of data * Schema is fixed * Easy to visualize * A lot of Math * Ready-made query language, SQL
- Shared data(Semi-structured Data) * Self-describing structure * The schema can easily be changed * Helps to not worry about object-relational impedance mismatch * Support for nested or hierarchical data * Support for lists of objects * Can represent the information of some data sources that cannot be constrained by schema * Flexible format for data exchange between different types of databases
- Overview and choose of document db * Why not xml, json in SQL/Oracle - speed * Why not RavenDB – not usable * Why not Mongo – too complicated in configuration
- Standard for JSON in RDMS from ISO Only Oracle and partially SQL Server support parts of standart
- non standard json operators but with native jsonb
- Oleg Bartunov(Бартунов) RIT++ 2017 Yahoo! Cloud Serving Benchmark
- show how jsonb works everything is good with JOSNB except it is not supported by EF
- One standard(IQueryable) for access both local data and shared data PostgreSQL 9.5+ .NET 4.6+ how it works in short Document Database & Event store
- start up with marten set up storage write data read data
- Advanced features of Marten
- B-Tree and GIN indexes, how to use it in Marten
- Shot summary Live experience of using Marten in company Amount of data that we used
