-----------------------------------------------
Hi [~TsReaper]
Im sory for a long delay. I was actyally trying to develop a PoC fix for this
problem. I think I managed to at least proof a concept. You can find my raft PR
here -> https://github.com/apache/flink/pull/21393 The code from this PR made
the SQL from this ticket to compile and execute which is at least something :)
The idea is to enhance FunctionSplitter that for every codeBlock
(getMergedCodeBlocks method) that is bigger than "maxMethodLength" try to
further split it by calling two new splitters that I've created:
1. BlockStatementSplitter
2. BlockStatementGrouper
The BlockStatementSplitter splits body of WHILE, IF/ELSE statements to new
methods. The original statement is rewritten that will call those new methods.
Next ,the *BlockStatementGrouper* is groping those new method calls created by
*BlockStatementSplitter* to blocks with lengths < "maxMethodLength" and
extracting those to yet another new method. Finally *BlockStatementGrouper*
rewrites original code block to call methods created by *BlockStatementGrouper*.
For example, an input statement:
{code:java}
while (
(kvPair$9687 =
(org.apache.flink.api.java.tuple.Tuple2<org.apache.flink.table.data.binary.BinaryRowData,
org.apache.flink.table.data.binary.BinaryRowData>) iterator.next()) != null) {
key$6207 = (org.apache.flink.table.data.binary.BinaryRowData)
kvPair$9687.f0;
val$9688 = (org.apache.flink.table.data.binary.BinaryRowData)
kvPair$9687.f1;
// prepare input
local$5912.replace(key$6207, val$9688);
if (lastKey$6208 == null) {
// found first key group
lastKey$6208 = key$6207.copy();
agg0_sumIsNull = true;
agg0_sum = ((org.apache.flink.table.data.DecimalData) null);
agg1_sumIsNull = true;
agg1_sum = ((org.apache.flink.table.data.DecimalData) null);
agg3_sum = ((org.apache.flink.table.data.DecimalData) null);
agg3_sum = ((org.apache.flink.table.data.DecimalData) null);
} else if (lastKey$6209 == null) { agg2_sum =
((org.apache.flink.table.data.DecimalData) null);
agg3_sumIsNull = true;
} else { agg2_sumIsNull = true;
}};
{code}
will be converted by BlockStatementSplitter to:
{code:java}
while (
(kvPair$9687 =
(org.apache.flink.api.java.tuple.Tuple2<org.apache.flink.table.data.binary.BinaryRowData,
org.apache.flink.table.data.binary.BinaryRowData>) iterator.next()) != null) {
top_whileBody0_0();
if (lastKey$6208 == null) {
// found first key group
top_whileBody0_0_ifBody0();
} else if (lastKey$6209 == null) {
top_whileBody0_0_ifBody1_ifBody0();
} else { top_whileBody0_0_ifBody1_ifBody1();
}};
{code}
Further this will be converted by BlockStatementGrouper with maxMethodLength
parameter set to 4000 to:
{code:java}
while (
(kvPair$9687 =
(org.apache.flink.api.java.tuple.Tuple2<org.apache.flink.table.data.binary.BinaryRowData,
org.apache.flink.table.data.binary.BinaryRowData>) iterator.next()) != null) {
top_rewriteGroup_0();
}
{code}
New methods body would be:
{code:java}
private void top_whileBody0_0_ifBody1_ifBody0 {
agg2_sum = ((org.apache.flink.table.data.DecimalData) null);
agg3_sumIsNull = true;
}
private void top_whileBody0_0_ifBody1_ifBody1 {
agg2_sumIsNull = true;
}
private void top_whileBody0_0 {
key$6207 = (org.apache.flink.table.data.binary.BinaryRowData) kvPair$9687.f0;
val$9688 = (org.apache.flink.table.data.binary.BinaryRowData) kvPair$9687.f1;
local$5912.replace(key$6207, val$9688);
}
private void top_whileBody0_0_ifBody0 {
lastKey$6208 = key$6207.copy();
agg0_sumIsNull = true;
agg0_sum = ((org.apache.flink.table.data.DecimalData) null);
agg1_sumIsNull = true;
agg1_sum = ((org.apache.flink.table.data.DecimalData) null);
agg3_sum = ((org.apache.flink.table.data.DecimalData) null);
agg3_sum = ((org.apache.flink.table.data.DecimalData) null);
}
void top_rewriteGroup_0() {
top_whileBody0_0();
if (lastKey$6208 == null) {
// found first key group
top_whileBody0_0_ifBody0();
} else if (lastKey$6209 == null) {
top_whileBody0_0_ifBody1_ifBody0();
} else {
top_whileBody0_0_ifBody1_ifBody1();
}
}
{code}
