Jonathan Ellis updated CASSANDRA-946: ------------------------------------- Attachment: 946-v7.txt looks pretty good, v7 tweaks it to allow using preload even with less than 100% cached rows by just reading the first rows in the sstables up to the cache capacity. (obviously this is not always useful but for cache of 90% for instance there is no reason to disallow it entirely.) what do you think? > Add a configuration and implementation to populate the data into memory > ----------------------------------------------------------------------- > > Key: CASSANDRA-946 > URL: https://issues.apache.org/jira/browse/CASSANDRA-946 > Project: Cassandra > Issue Type: Improvement > Components: Core > Affects Versions: 0.7 > Environment: Linux, Cassandra > Reporter: Vijay > Assignee: Vijay > Priority: Minor > Fix For: 0.7, 0.8 > > Attachments: 946-Add_Config_v003.txt, 946-Documentation_v002.txt, > 946-Load_Data_v003.txt, 946-v4.txt, 946-v5.txt, 946-v6.patch, 946-v7.txt, > screenshot.png > > > Proactively load data into the memory when the node is started, there will be > a configuration to enable this function and will be per Columnfamily. The > requirement is to speed up the reads for data which can reside 100% of in the > memory.... In addition to enabling the RowCache to 100% we can do this so as > upgrades or any other means of restart will not clear the cache in the server. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
