Re: [Dev] [SP]Incremental processing not working with SP + RDBMS

[Gokul Balakrishnan]

Hi Charini,

Are you sure that this worked with the RDBMS store before? It has not
supported function namespaces from the start.

Thanks,

Re: [Dev] [SP]Incremental processing not working with SP + RDBMS

[Charini Nanayakkara]

Hi Gokul,

It worked when I tested without the retrieval part of incremental processor
if I remember correctly.

To be more precise, there are two parts in incremental aggregation. The
part where we aggregate, and the part where we retrieve.

RDBMS store is used in the aggregation level. We refer to that table and
perform a join to retrieve aggregated values in the second phase.

The issue occurs due to a function 'within'  (which has the namespace
'incrementalAggregator') being used in the retrieval part of the query. The
retrieval implementation was not done at the time I tested with RDBMS.
Hence I seem to have overlooked this issue. It should still work when only
the aggregation part is defined in the siddhi application. I will further
verify this matter and update you. Will check how we can fix this.

Thank you
Charini

Hi Suho,

Incremental processing is not working with RDBMS due to a new change
introduced at RDBMS extension level which rejects function namespaces. I
will discuss this with Gokul as well and find a solution.

Thank you
Charini

Hi Charini

Please look into this.

The attached Siddhi file is not compiling with RDBMS Aggregation.

Thanks
