There is also a GitHub mirror at {{https://github.com/apache/asterixdb-site}}.
There are instructions how to edit and build the site at

ASTERIXDB-1479: Change storage valid int and add explicit version

This change will stop old versions from possibly corrupting data written
by newer versions of Hyracks. It also adds an explicit version to the
tree metadata that must match the version at runtime.

[jira] [Commented] (ASTERIXDB-1556) Prefix-based multi-way Fuzzy-join generates an exception.

[Michael J. Carey (JIRA)]

[ 
https://issues.apache.org/jira/browse/ASTERIXDB-1556?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=15399984#comment-15399984
 ] 

Michael J. Carey commented on ASTERIXDB-1556:
-

Agreed.  A few big-picture-ish thoughts are:
1 - Having many operators is not necessarily a problem (as it seems Wenhai also 
pointed out).  The real question will be, for these plans, how much 
simultaneously-in-use memory can there be in the worst case (where every 
operator is using its budget).  We'll see what Taewoo's analysis shows.
2 - I agree that N=2 will be the normal case and that we should optimize that 
at first.  However, since AQL allows users to write N-way joins for N>2, they 
have to work - as in, they need to return answers eventually (as opposed to 
blowing up).  Users will quickly learn not to ask queries that take too long - 
but - we can't fall over with an NPE or OOM.
Let's see what Taewoo's analysis turns up!

[jira] [Commented] (ASTERIXDB-1556) Prefix-based multi-way Fuzzy-join generates an exception.

[Chen Li (JIRA)]

 ] 

Chen Li commented on ASTERIXDB-1556:


Per our discussion today, the next step is the following.  Taewoo will look at 
the 3-way fuzzy-join plan, and manually calculate the total amount of budget 
memory.  If the total amount is within the available memory but the plan runs 
out of memory, then there should a bug in the way we use memory.  We either 
have memory leak, or are not respecting the budget within each operator when 
allocating memory.

Till Westmann has submitted this change and it was merged.

Change subject: Implement EXPLAIN for SQL++

Implement EXPLAIN for SQL++

- move some code from static methods in ResultUtils to a stateful
  ResultPrinter to facilitate reuse (we create one ResultWriter per request)
- tiny cleanup in LogicalOperatorPrettyPrintVisitor

Change in asterixdb[master]: Implement EXPLAIN for SQL++

[Till Westmann (Code Review)]

Hello Yingyi Bu, Jenkins,

I'd like you to reexamine a change.  Please visit

https://asterix-gerrit.ics.uci.edu/1020

to look at the new patch set (#8).

Change subject: Implement EXPLAIN for SQL++
..

Implement EXPLAIN for SQL++

- move some code from static methods in ResultUtils to a stateful
  ResultPrinter to facilitate reuse (we create one ResultWriter per request)
- tiny cleanup in LogicalOperatorPrettyPrintVisitor

Attached the asterix plan, hyracks plan as well as the workflow. Notice that 
the number in the pdf comes from the operators (node number) and the connectors 
(line number).

Change in asterixdb[master]: Implement EXPLAIN for SQL++

[Till Westmann (Code Review)]

Hello Yingyi Bu, Jenkins,

I'd like you to reexamine a change.  Please visit

https://asterix-gerrit.ics.uci.edu/1020

to look at the new patch set (#7).

Implement EXPLAIN for SQL++

- move some code from static methods in ResultUtils to a stateful
  ResultPrinter to facilitate reuse (we create one ResultWriter per request)
- tiny cleanup in LogicalOperatorPrettyPrintVisitor
