IBX-704: Added aggregation support to NodeFactory #1792

mateuszbieniek · 2021-07-02T09:50:14Z

Jira's issue: https://issues.ibexa.co/browse/IBX-704

requires:
ezsystems/ezplatform-kernel#215
ezsystems/ezplatform-solr-search-engine#215

Children counts call to Solr can create an overhead for load-subtree calls.
This PR adds Aggregation support for NodeFactory to speed it up when supported.

@webhdx would be great for reviewing this next week.

I'm not too experienced with SOLR/Elastic usage so it needs attention from Adam or Andrew. Anyway I don't quite like the general idea here. NodeFactory becomes more and more complicated/bloated with all performance improvements. Would be nice to provide alternative NodeFactory which could utilize different handling when ES/SOLR is being used. But I understand this would require more refactoring and providing some extension points. I put some remarks in the comments, please consider them.

I think this should be configurable if there is possibility to fine tune performance on different setups.

It would be cleaner if you used empty array instead of null value.

Passing null here indicates that Aggregation results are not available (for example: using a legacy search engine) and the "legacy" way of counting children should be used inside the supplyChildrenCount method. An empty array is a totally valid result of aggregation. I can change it to pass to an empty array, but we will have to introduce something like $isAggregationSupported and pass it alongside to supplyChildrenCount

@mateuszbieniek I don't see how distinguishing between [] and null would change the behavior of this method in its current state. Could you show a snippet with [] instead of null?

There are two possibilities:

Aggregations are not supported ($aggregationResult is null). Every single container node will have $this->countSubitems($node->locationId); called

Aggregations are supported and $aggregationResult is an array.

$totalCount = isset($aggregationResult[$node->locationId]) ? $aggregationResult[$node->locationId] : 0;

If $aggregationResult has key $node->locationId then node has children, if a key does not exist, this means that there children count is 0;

So, if I pass it as empty array, when aggregations are not supported current state of method will result on 0 children count for all nodes.

I can change it to an empty array but will have to add a check for aggregation support inside supplyChildrenCount method.

I've changed the check inside from supplyChildrenCount:

if ($aggregationResult) {

to

if ($aggregationResult !== null) {

This should reduce the confusion.

With the change to the method behavior it's clear why you need it there. With test coverage we could avoid this discussion, because you would spot a mistake immediately.
One final request related to forward compatibility of rebranding:
