Sorry for the typo...
I mean it will not take too much time.

Hi, Yuval.
I have opened a ticket about this[1]. But I don't think we have any
solution to solve.
Do you have time to help us to solve this? I think it will take too much
time.

Thank you Shenkai,
That does explain what I'm seeing.
Jark / Shenkai - Is there any workaround to get Flink to work with push
watermarks and predicate pushdown until this is resolved?

Hi, Yuval, Jark, Timo.
Currently the watermark push down happens in the logical rewrite phase but
the filter push down happens in the local phase, which means the planner
will first check the Filter push down and then check the watermark push
down.
I think we need a rule to transpose between the
Hi Jark,
Even after implementing both, I don't see the watermark being pushed to the
tablesource in the logical plan and avoids predicate pushdown from running.

Hi Yuval,
That's correct you will always get a LogicalWatermarkAssigner if you
assigned a watermark.
If you implement SupportsWatermarkPushdown, the LogicalWatermarkAssigner
will be pushed
into TableSource, and then you can push Filter into source if source
implement SupportsFilterPushdown.

Hi Timo,
After investigating this further, this is actually non related to
implementing SupportsWatermarkPushdown.
Once I create a TableSchema for my custom source's RowData, and assign it a
watermark (see my example in the original mail), the plan will always
include a LogicalWatermarkAssigner. T
Hi Yuval,
sorry that nobody replied earlier. Somehow your email fell through the
cracks.
If I understand you correctly, could would like to implement a table
source that implements both `SupportsWatermarkPushDown` and
`SupportsFilterPushDown`?
The current behavior might be on purpose. Filt
