Please reply to this post with proposed topics to discuss. If these proposed topics won’t take much time, then the remainder would be used to present the design of the Hash-Join Spill; I will describe the basic changes, and Tim will talk briefly about the memory calculator used in deciding “when to spill”. These basic changes to the Hash-Join for spilling are described in the design document: https://urldefense.proofpoint.com/v2/url?u=https-3A__docs.google.com_document_d_1-2Dc-5FoGQY4E5d58qJYv-5Fzc7ka834hSaB3wDQwqKcMoSAI_edit-23heading-3Dh.6wkihnd871vj&d=DwIGaQ&c=cskdkSMqhcnjZxdQVpwTXg&r=EqulKDxxEDCX6zbp1AZAa1-iAPQGgCioAqgDp7DE2BU&m=OGzUcUS9n9pZ7zMbkeUXfCL9fqX_DFDuwZG_9OXA_B8&s=zuCTx3B9i23dHLsTca2nzR0pmQD49yrrxiyBWsHZ63A&e= The Hangout link: https://urldefense.proofpoint.com/v2/url?u=https-3A__plus.google.com_hangouts_-5F_event_ci4rdiju8bv04a64efj5fedd0lc&d=DwIGaQ&c=cskdkSMqhcnjZxdQVpwTXg&r=EqulKDxxEDCX6zbp1AZAa1-iAPQGgCioAqgDp7DE2BU&m=OGzUcUS9n9pZ7zMbkeUXfCL9fqX_DFDuwZG_9OXA_B8&s=MutN0ei7uja5VbpK0eu8gtITT6iHiwYWbaXgKLZucL8&e= Thank you, Boaz
