GEODE-5534: Force CI to re-run
> With oql indexes and compression enabled, memory usage is greater after
> compression than before

> A test that shows the behavior is:
> - xml configuration like:
> {noformat}
> <region name="order">
> <region-attributes scope="distributed-ack"
> data-policy="persistent-replicate" disk-store-name="orderDiskStore"
> disk-synchronous="false" cloning-enabled="true">
> <compressor>
> <class-name>org.apache.geode.compression.SnappyCompressor</class-name>
> </compressor>
> </region-attributes>
> <index name="order_clOrdID" from-clause="/order index_from"
> expression="index_from.clOrdID" type="range"/>
> <index name="order_externalOrderID" from-clause="/order index_from"
> expression="index_from.externalOrderID" type="range"/>
> <index name="order_externalOrderIDSource" from-clause="/order index_from"
> expression="index_from.externalOrderIDSource" type="range"/>
> <index name="order_orderID" from-clause="/order index_from"
> expression="index_from.orderID" type="range"/>
> <index name="order_parentOrderID" from-clause="/order index_from"
> expression="index_from.parentOrderID" type="range"/>
> </region>
> {noformat}
> - an Order object defining string fields for clOrdID, externalOrderID,
> orderID and parentOrderID and an enum field for externalOrderIDSource
> Here are some histograms showing the behavior:
> With indexes and no compression:
> {noformat}
