Dear solr users, when updating documents in bulk (i.e. 40.000 documents at once), and only changing the value of a single Boolean-Flag, I currently re-index all whole 40.000 objects. However, the process of obtaining all relevant information for each object from the database is one of relatively high cost.
I now wonder, if in this situation it would be a good idea to implement a single-field update routine using atomic updates? In that case, I could skip any necessary lookups in the relational database, since the only information would be the new value for that Boolean-Flag, and the list of those 40.000 document ids. I am aware of the requirements to use atomic updates, but as I understood, those would not have a big impact on performance and only a slight increase in index size? What is your opinion on that? Thanks for your input, have a nice evening! Sebastian
