Re: Transactions in Druid?
Hi Edward, There are a couple of ways to do transactional updates to Druid today: 1) When using streaming ingestion with the "parseBatch" feature (see io.druid.data.input.impl.InputRowParser), rows in the batch are inserted transactionally. 2) When using batch ingestion in overwrite mode (the default), all operations are transactional. Of course, you must be willing to overwrite an entire time interval in this mode. With (1) scans are not transactionally consistent. With (2) scans of a particular interval _are_ transactionally consistent, due to the nature of how we handle overwrite-style ingestion (the new segment set has a higher version number, and queries will use either the older or newer version). However Druid never offers read-your-writes consistency. There is always some delay (however small) between when you trigger an insert and when that insert is actually readable.

Podling Report Reminder - June 2018
Dear podling, This email was sent by an automated system on behalf of the Apache Incubator PMC. It is an initial reminder to give you plenty of time to prepare your quarterly board report. The board meeting is scheduled for Wed, 20 June 2018, 10:30 am PDT. The report for your podling will form a part of the Incubator PMC report. The Incubator PMC requires your report to be submitted 2 weeks before the board meeting, to allow sufficient time for review and submission (Wed, June 06). Please submit your report with sufficient time to allow the Incubator PMC, and subsequently board members to review and digest. Again, the very latest you should submit your report is 2 weeks prior to the board meeting. Candidate names should not be made public before people are actually elected, so please do not include the names of potential committers or PPMC members in your report. Thanks, The Apache Incubator PMC Submitting your Report -- Your report should contain the following: * Your project name * A brief description of your project, which assumes no knowledge of the project or necessarily of its field * A list of the three most important issues to address in the move towards graduation. * Any issues that the Incubator PMC or ASF Board might wish/need to be aware of * How has the community developed since the last report * How has the project developed since the last report. * How does the podling rate their own maturity. This should be appended to the Incubator Wiki page at: https://wiki.apache.org/incubator/June2018 Note: This is manually populated. You may need to wait a little before this page is created from a template. Mentors --- Mentors should review reports for their project(s) and sign them off on the Incubator wiki page. Signing off reports shows that you are following the project - projects that are not signed may raise alarms for the Incubator PMC.

Transactions in Druid?
Hi, Community, Do we have any existing or perceived use cases of transactional (multi-row) updates to Druid? Same about transactionally consistent scans? Thanks, Edward
