Hi Shushuai,
Like Mikhail said, bulking your updates will be way faster than sending individual update requests. Depending on how large (or should I say small) the actual value is you're setting, you might be able to send a few hundred or even a few thousand updates per request. If you're querying one million documents to update from Solr, have a look at Cursors in the ref guide. https://solr.apache.org/guide/solr/latest/query-guide/pagination-of-results.html#fetching-a-large-number-of-sorted-results-cursors Thomas Op di 29 nov. 2022 om 07:31 schreef Mikhail Khludnev <m...@apache.org>: > Hello Shushuai. > There's no 'columnar update' handler which you are asking for.
