Hi Guys, I found in documentation for 3.2 version new amazing feature $filter(aggregation) which significant improve performance of array filtering. Unfortunately, I couldn't found java API for this feature usage. Could you provide details when this feature will come to java driver? Also I will grateful if you provide some workaround how to use this feature with current driver. |

The driver currently provides typed builders only for aggregation stages and accumulators, but not the full expression language, which $filter is a part of. |

@Jeff Yemin, Thanks, I'm seeing. I'll make my own builder, but anyway are you planning implement this method? |

This type of question if better handled in the MongoDB user forum, where I see you already started this thread. |
