Re: List of serious issues fixed in 3.0.x
Sankalp, thanks for sending the spreadsheet and Josh for preparing this analysis (pending image issues; look forward to reading)! I'd encourage everyone involved in the project to review the list of tickets captured here. These issues aren't theoretical and represent real scenarios that result in data loss, data corruption, incorrect responses to queries, and other violations of fundamental properties of the database. As a community, we've made great progress over the past two years. The focus on quality has dramatically improved the safety of Cassandra as a database -- especially in the most recent patchlevel releases of the 3.0.x and 3.11.x series. That said, we're also not out of the woods. The following three issues have been reported and confirmed genuine in the past week: – CASSANDRA-15789: Rows can get duplicated in mixed major-version clusters and after full upgrade – CASSANDRA-15778: CorruptSSTableException after a 2.1 SSTable is upgraded to 3.0, failing reads – CASSANDRA-15790: EmptyType doesn't override writeValue so could attempt to write bytes when expected not to Regarding Dinesh's point on regression tests, we're beginning to go even further. In response to the issues in this spreadsheet, we're evolving new approaches toward *active assertion* of data integrity. C-15789 adds read/repair/compaction-path detection of primary key duplication, a great way to audit and remediate instances of corruption detected in a cluster. Repaired data tracking introduced in C-14145 and improvements to Preview Repair are also great examples, enabling Cassandra to assert the consistency of repaired data (something we'd taken for granted). Active assertion of data integrity invariants in Cassandra is an important frontier -- and one we need to explore further. Previously-adopted methodologies like property-based testing, large-scale diff tests asserting identity of data between 2.1- and 3.0.x clusters post-upgrade via billions of randomized queries, fault injection, model-based tests, CI improvements, and flaky test reduction have helped us make huge progress toward quality and continue to pay dividends. I want to thank everyone for their work on safety and stability. It's clear we have more ahead, but it's critical to Apache Cassandra's future and toward shipping a 4.0 release that users can trust and adopt quickly. – Scott From: Joshua McKenzie Sent: Thursday, May 7, 2020 9:31 AM Cc: dev@cassandra.apache.org Subject: Re: List of serious issues fixed in 3.0.x Hearing the images got killed by the web server.

I did a little analysis on this data (any defect marked with fixversion 4.0 that rose to the level of critical in terms of availability, correctness, or corruption/loss) and charted some things the rest of the project community might find interesting: 1: Critical (availability, correctness, corruption/loss) defects fixed per month since about 6 months before 3.11.0: [image: monthly.png] 2: Components in which critical defects arose (note: bright red bar == sum of 3 dark red): [image: Total Defects by Component.png] 3: Type of defect found and fixed (bright red: cluster down or permaloss, dark red: temp corrupt/loss, yellow: incorrect response): [image: Total Defects by Type.png] My personal takeaways from this: a ton of great defect fixing work has gone into 4.0.
