Hi,
Please someone tell whether Javacompute node (using Java) or Compute node(using ESQL) will be bale to give better throughput(mean faster processing of messages).
Thanks in advance |

| It used to be that ESQL performed about 10-15% faster than Java. Perhaps that gap has reduced now. My bet would that ESQL still performs a little faster than Java. |

| Stick to ESQL for consistency in the broker. Think of Java as for "emergencies only". |

It really depends on what you're trying to do. As a basic rule of thumb, use ESQL for complex message manipulation, Java for general-purpose logic.
Also, do consider Mapping and XSLT and WTX as alternative transformation options.
If in doubt, use the language you have most skills in. |

AFAIK JCN's are faster in processing then eSQL...
Sometime back i had testing the performance of eSQl code vs custome node written in C and found a huge performance difference..
BUT entry n exit in JCN is costly affair and hence its not recommended to have 2-3 JCNs in one flow...
eSQL is easy and is broker language so stick to it for general transformation/routing logic...
I use JCN for XML operation like XPath etc etc

Most important ...
eSQL is much easier tthe java  {Not many people would support me on this though... }
eSQL is faster for the things which can be done in it e.g. formatting, transformation, routing etc etc
eSQL is broker's in built langague...
as zpat said.. use java when absolute necessary... else always stick to eSQL
