Re: Optimistic Serializable SQL Transactions

Hi Justin, Thank you for sharing a details about your use case. Quite interesting. It seems that in Ignite something like that is possible with optimistic cache transactions (key-value API). Technically it seems to be achievable when transaction protocol accumulates transaction read-write set in

Re: Striim support for Ignite

So my use case is to be able use SQL/Query API on my existing system to retrieve from Ignite in-memory Grid. I don't expect a lot of write-through from Ignite. I DO expect most of my writes to happen on my RDBMS. I don't see any option rather than writing custom code on RDBMS(may be triggers) to

Re: Ingite node in SpringBoot App

Thanks! That worked. Now when I try to fetch object using thin client from a seperate process I get no object. However, when I fetch object using the same server process I get object. Difference on fetching object is the usage of Ignite or IgniteClient. Attached is the client driver.

Hi Ilya, Sorry for the late response. We don't use lock mechanism in our environment. We have a lot of put, get operaitons, as far as i remember these operations does not hold the locks. In addition to these operations, in many update/put operations we use CacheEntryProcessor which also does not

so spark + jdbc thin client is the only way to go forward? Reading:- val df = spark.read .format("jdbc") .option("url", "jdbc:ignite:thin://18.206.247.40") .option("fetchsize",100) //.option("driver", "org.apache.ignite.IgniteJdbcDriver") .option("dbtable", "Person2").load()

Re: Ingite node in SpringBoot App

This happens because you create your node inside try () statement. So it is being stopped as soon as try section ends. If you want to keep it active change code to try { Ignite ignite = Ignition.start("example-ignite.xml"); On Fri, Oct 18, 2019 at 4:35 PM niamin wrote: > springbeans.zip
