ZhaoYang updated CASSANDRA-13622: --------------------------------- Fix Version/s: 4.0 > Better config validation/documentation > -------------------------------------- > > Key: CASSANDRA-13622 > URL: https://issues.apache.org/jira/browse/CASSANDRA-13622 > Project: Cassandra > Issue Type: Bug > Reporter: Kurt Greaves > Assignee: ZhaoYang > Priority: Minor > Labels: lhf > Fix For: 4.0 > > > There are a number of properties in the yaml that are "in_mb", however > resolve to bytes when calculated in {{DatabaseDescriptor.java}}, but are > stored in int's. This means that their maximum values are 2047, as any higher > when converted to bytes overflows the int. > Where possible/reasonable we should convert these to be long's, and stored as > long's. If there is no reason for the value to ever be >2047 we should at > least document that as the max value, or better yet make it error if set > higher than that. Noting that although it's bad practice to increase a lot of > them to such high values, there may be cases where it is necessary and in > which case we should handle it appropriately rather than overflowing and > surprising the user. That is, causing it to break but not in the way the user > expected it to :) > Following are functions that currently could be at risk of the above: > {code:java|title=DatabaseDescriptor.java} > getThriftFramedTransportSize() > getMaxValueSize() > getCompactionLargePartitionWarningThreshold() > getCommitLogSegmentSize() > getNativeTransportMaxFrameSize() > # These are in KB so max value of 2096128 > getBatchSizeWarnThreshold() > getColumnIndexSize() > getColumnIndexCacheSize() > getMaxMutationSize() > {code} > Note we may not actually need to fix all of these, and there may be more. > This was just from a rough scan over the code. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
