Lineage: DataStax ran Cassandra Summit (San Francisco/Santa Clara, plus Europe/Tokyo editions) until 2016, then replaced it with its own conference, DataStax Accelerate (May 2019, National Harbor MD). Accelerate 2020 (San Diego and London) was cancelled on March 5, 2020 for COVID-19 and no later Accelerate was found. In parallel, the Apache Cassandra community held an 'Apache Cassandra Summit' plus NGCC as part of ApacheCon NA 2019 (Las Vegas). The Cassandra Summit name returned in 2023 under the Linux Foundation with the Apache Cassandra PMC: planned for March 13-14, 2023 in San Jose, postponed and held Dec 12-13, 2023 in San Jose, co-located with AI.dev; DataStax ran the free online 'Cassandra Forward' on March 14, 2023 (and again on March 11, 2025). No standalone Cassandra Summit after 2023 (gap 2024-2026): the community instead runs a Cassandra track at the ASF's Community Over Code (Denver Oct 2024, Minneapolis Sept 2025, Glasgow Oct 2026; tracked under the community-over-code series), plus DataStax 'Cassandra Day' one-day events (2022) and meetups. 2020-2022 had no summit (only ApacheCon@Home tracks and the online Apache Cassandra World Party, July 2022). Social accounts are the Apache Cassandra project's (the LF event used Linux Foundation accounts).
