So my client want me to validate all messages coming from the MB and from the WCS, headers and body.
What this means is that potentially I can have alot data in the body which is being output by the WCS and they want me to validate each variable, line by line. They then want me to compile a list of of all the errors and then throw that, instead of throwing at the first error.
So my question is, which is faster to compile a list of validations errors, an ESQL compute node or a Java compute node?
Thanks

My question is which version of WMB? Java support improves as you move through from older versions to newer, so Java in 6.1.0.3 runs slower than Java in 8.0.0.2.
But "slower" does not mean "slow".
A more important point in that 8.0.0.2 badly written ESQL will perform worse than well written Java, and well written ESQL will better than badly written Java. I'd be more concerned with the code than any marginal difference between the execution of 2 1st class WMB languages.

If using references, ESQL Compute is slightly faster than JCN. In a small test run on 7.0.0.2 in 2010, on 1 million records, side-by-side with three lines of validation (1m x 3 = 3m validations), ESQL Compute finished about 3 seconds faster than JCN. In other words, the difference is negligible, but ESQL outperforms JCN.
