Adaptive asymmetric-key compression for idempotent data stores in computer messaging

A system comprising:

• a memory;
• and
• a processing device coupled to the memory, the processing device to perform operations comprising:
• determining, by a server node, to invoke a compression process used to compress message identifiers stored in a first node of a cluster of nodes, wherein the nodes are managed by the server node;
• receiving a first public key associated with the first node;
• generating a compression key;
• generating a first encrypted compression key by encrypting the compression key with the first public key;
• sending, to the first node, the first encrypted compression key;
• and
• receiving, from the first node, a second notification of storing, in a compressed form using a key decrypted from the first encrypted compression key, at least one message identifier in a data store of the first node.

A non-transitory computer-readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to perform operations comprising:

• receiving, by a server node, a first notification indicating that a first message received by a first node of a cluster of nodes is not a redundant message and cannot be stored by a data store of the nodes, wherein the nodes are managed by the server node;
• determining to invoke a compression process used to compress message identifiers stored in the first node;
• receiving a first public key associated with the first node;
• generating a compression key;
• generating a first encrypted compression key by encrypting the compression key with the first public key;
• sending, to the first node, the first encrypted compression key;
• and
• receiving, from the first node, a second notification of storing, in a compressed form using a key decrypted from the first encrypted compression key, at least one message identifier in a data store of the first node.
