## Trace format
The traces are zstd compressed and have the following format:

typedef struct __attribute__((packed)) {
    uint32_t timestamp;
    uint64_t obj_id;
    uint32_t obj_size;
    int64_t next_access_vtime;  // -1 if no next access
} request_t;
The compressed traces can be used with libCacheSim without decompression.
