Some M:N². It is not pure fiction but taken from a closer view of OEX Contests that we run on a regular base. #Other 9 2 1 336

In a previous example, this all was processed in memory.

Article Robert Cemper · Mar 19, 2022 2m read Compare Global Write in ePy vs. ISOS/COS This example demonstrates the difference you may experience when you write toGllobals directly from Embedded Python compared to native ObjectScript. To make this demo useful I start 2 background jobs that simply write sequentiallyto a dedicated global. A common control method signals for a synchronous start.Similar a common stop & view interrupts data feeding. That's the principle process: #Embedded Python #Globals #ObjectScript #InterSystems IRIS 2 1 0 221
Article Robert Cemper · Mar 8, 2022 2m read ePython - mixed or pure ? You may have seen my series of articles on GlobalToJSON closing with Embedded Python.And to me, Embedded means inside a Class and not PEX or other external variants.The first variants showed that ePy is not an ultimate requirement. ISOS/COS may do it as well.Here I try to position ePy inside IRIS. #Embedded Python #Globals #ObjectScript #InterSystems IRIS 6 1 0 319

Article Robert Cemper · Jan 2, 2022 3m read DB Migration using SQLgateway Thanks to @Yuri Marx we have seen a very nice example for DB migration from Postgres to IRIS.My personal problem is the use of DBeaver as a migration tool.Especially as one of the strengths of IRIS ( and also Caché) before is the availability of theSQLgateways that allow access to any external Db as long as for them an access usinig JDBC or ODBC is available. So I extended the package to demonstrate this. #Best Practices #Data Import and Export #Docker #SQL #InterSystems IRIS 10 3 2 651
