After some editing for readability, the object and datastream text is highlighted in bold to show data of interest.
Some of these elements are:
87a0a8c7505d64 refers to root node UUID
The grayed out text refers to Modeshape classes responsible for data representation and serialization
...
- The file contains binary data for specifying different internal attributes, so the file might show garbage characters or numbers in strings. /children0<key87a0a8c317f1e7jcr:systemnamejcr:system1Skey387a0a8c7505d64 . Similarly, if object 'chandni' had siblings, the array would appear in the binary as:
- Name/string (53f49a07-8e14-41a1-bab3-abc59d86846enamechandni)
87a0a8c7505d64 refers to root node UUID
Similary, for the datastream:

Using the Infinispan 6.x deprecated FileCacheStore (specified via file/infinispan.xml, currently our ModeShape is on 5.x) results in creation of hundreds of binary files (compared to LevelDB). A hashing algorithm is used to map keys to buckets. The value files contain serialized ModeShape nodes. The key files can be read using org.infinispan.schematic.internal.document.BsonReader. (It does not seem possible to read these files using existing bson tools, like mongoDB bsondump, but further inspection is needed.)
