See https://ignite.apache.org/releases/mobile/org/apache/ignite/configuration/BinaryConfiguration.html#isCompactFooter() .

Hi,

I implement a cacheStore, this cachestore will persist a binaryObject into bytes= and store in MySQL blob.=C2=A0
Exceptions occurred when c= alling loadCache function:
binaryObject.deserialize() will throw = exceptions like "Cannot find metadata for object with compact footer: = -1615140068"
If =C2=A0I just= put the binaryObject=C2=A0into the = cache=C2=A0without deserialization ,= it is ok. =C2=A0when i get it and use it, it will throw the exception agai= n.
How to fix it? Thanks in advance.
