I think users can live with a 1-minute delay, but I'll have to ask :) Is the log file the best resource for information on (soft) commit-duration? >> In our case, we don't have a huge number of documents being >> created in a minute.

Sorry, that was just a copy/paste directly from the default solr.in.sh script that ships with Solr. I wouldn't do a 3-second soft-commit. > I believe that when you use "bin/solr create" to create an index > with the default config, that it does set the autoSoftCommit to 3 > seconds. Which as I stated, I believe to be far too frequent. Nope, it sets it to "never soft commit", unless the defaults have changed since I built this service with, I think, 7.3.0. Is there any way to change this value at runtime, or does it require a service-restart? - -chris -----BEGIN PGP SIGNATURE----- Comment: Using GnuPG with Thunderbird - https://www.enigmail.net/ iQIzBAEBCAAdFiEEMmKgYcQvxMe7tcJcHPApP6U8pFgFAlyKxt8ACgkQHPApP6U8 pFg9ChAAkSgsvn3+xufyLM9bA8WIWqICwmDWRdFM9nbSiy4bDH1Zl/86FKjzcvbB lmyVFYlpFGedcSKLVsqXGEZiu8n0YgR6iVw6udfIJOWzex5JkwUBUsmS6bHP5ZAj 8wkTyWPyBQVBSBWUxQnEzfrgJCFxzEbzBt8no0gt0f7vbgXm+HaFBkb+l2MQzTK9 wrhsLh36cb17ig+/w16Eo4Rq5VQ5f/P4Y7PkTfzS5CaWyPi16mTP8Z7vTxQ+ltHQ IPAVnZ4U6Tx4hFxf2Ox99qRX5wAlX0lMD063Gx7Q348Xn+u8VH8Aur8hudnb9Icf MK9OqU0bxdeWkhDxGDCuxY4h+t+kE1YI0cPI5KWTkBVAU24dCOAPkJQ0LMGs/rGR B3KareFltLztowvM8rxOeNcLzeoKn1ZpWrtPuK9tuaCy9LnwxgfTOGJFRuzhzxPF WHA7R4LtQrjjmAXV1a/BgkNVXXmGnq1qJNyICiV6nYS/ALJXKidrexgcyJ4FoWK4 uEcy/62mtbTVz7I4mdmkNH/vwjjOTxZy2FXfwoUIQYe9R2RHM9NbF0Fzzrvx3hQH vp2GD+AhzhIQUuqBe50XqUkC0T199ZgR4YkCBX7LdPDPcv54QgAfgjfImidQAiqn s+i/J/rBFZPTD2vAgix+A74UNpePrKhODt0GNg92J4NvTU8P9kM= =FwiA -----END PGP SIGNATURE-----
