Optimize Gaz passing a large UINT8Array as a parameter

I have a very simple smart contract that stores data.

The data has already been binary encoded in Javascript,

const data: UInt8Array = await compress(customBinaryEncoder(userData));

With an array size of 2000, I end up with a ridiculous amount of gaz.

How to make the best usage of uint256 solidity?

const optimizeForUint256 = (data: UInt8Array): DataFormat => {}

const Uint256toUInt8 = (data: any): UInt8Array => {}

I will then edit the contract method to accept DataFormat instead of uint8[].


 function addPatches( uint8[] memory data) public returns (bool  ok) {
     require(userIds[msg.sender] > 0, "must Be registered");
     uint64 id =  userIds[msg.sender];
     records[id].records.push(data);
     ok = true;
     return ok;
 }

No need to decode the data in solidity, it is stored as is.
