The following example takes the firstDynamicFramereceived, converts it to aDataFrameto apply the native filter method (keeping only records that have over 1000 votes), then converts it back to aDynamicFramebefore returning it. defFilterHighVoteCounts(glueContext, dfc) -> DynamicFrameCollection:df...
