Xu Mingmin commented on BEAM-301:
---------------------------------
[~julianhyde] It's great that {{EMIT}} is supported soon. Will look into it
for more details. QQ, from parser/grammar, is {{EMIT}} limited to Streaming or
workable for both? We would like to remove {{STREAM}} in Beam SQL as BEAM model
is unified for both streaming/batch data.
> Add a Beam SQL DSL

> Components: sdk-ideas
> Reporter: Jean-Baptiste Onofré
> Assignee: Xu Mingmin
>
> The SQL DSL helps developers to build a Beam pipeline from SQL statement in
> String directly.
> In Phase I, it starts to support INSERT/SELECT queries with FILTERs, one
> example SQL as below:
> {code}
> INSERT INTO `SUB_USEREVENT` (`SITEID`, `PAGEID`, `PAGENAME`, `EVENTTIMESTAMP`)
> (SELECT STREAM `USEREVENT`.`SITEID`, `USEREVENT`.`PAGEID`,
> `USEREVENT`.`PAGENAME`, `USEREVENT`.`EVENTTIMESTAMP`
> FROM `USEREVENT` AS `USEREVENT`
> WHERE `USEREVENT`.`SITEID` > 10)
> {code}
> A design doc is available at
> https://docs.google.com/document/d/1Uc5xYTpO9qsLXtT38OfuoqSLimH_0a1Bz5BsCROMzCU/edit?usp=sharing.
