Hi, The STDDEV* and VAR* SQL functions are documented on both Ignite and GridGain websites but are not implemented. https://www.gridgain.com/docs/latest/sql-reference/aggregate-functions#stddev_pop https://apacheignite-sql.readme.io/docs/aggregate-functions
The enums were commented out 6 years ago in https://github.com/apache/ignite/commit/63ec158e8dcfa9294c0727b8b778c87477416e10 So these do not work STDDEV_POP, STDDEV_SAMP, VAR_POP, VAR_SAMP, BOOL_OR, BOOL_AND, SELECTIVITY, HISTOGRAM. What's the story here? Shouldn't they be removed from the docs until/if they are ever implemented? Using Ignite 2.8.
