Hi all
I have a code page conversion issue
I have a flow that reads records from mongoDB and inserts the result into oracle
The mongo encoding is utf-8 , and the oracle is iso8859-8
Some special characters are not shown correctly in oracle – shows ???
I tried using the convertcharacterset function
What is your use case? Because this sounds vaguely like something that you
could implement implicitly with the HBase version by just creating one big
cache table with an eye for not overlapping column qualifiers and possibly
liberal use of HBase TTLs.

Is there any way to automate the creation of a DistributedMapCacheService
I was hoping I could do this via a template but it doesn’t to get exported the
way the DistributedMapCacheClientService does.
The client got created just fine but there’s no service.
I don’t see away to do this with
You can also use the Redis map cache implementation here as well.

I think you answered my question. The DistributedMapCacheServer that comes with
Nifi utilizes memory, as such, memory will be the constraint. If all I store in
the map cache is a key + a small avro/json with 4 columns, I could probably fit
millions without a problem.

If your using an external one like HBase I wouldn’t expect there to be any
issue assuming it had enough space. However if you are using the built in one
aka DistributedMapCacheServer then all the values need to fit in memory. One
thing I see an issue with is there isn’t a bulk way to get data
How many items within a distributed map cache service would be considered
excessive? I have a situation where I was considering dropping in around 200
million, but I was thinking where the limitation (wall or performance hit)
exists within the service.
