Trackers exceed cache size

[codihuston]

If a tracker is tracking, the size of the persistent storage cache (local storage) is increasing around 2KB per.

There is a snippet here that can calculate the remaining local storage space

[codihuston]

Only increases as tracker is ticking, or on "play"

[codihuston]

Remarking out the cache.writeQuery() in updateTracker resolver reduces the increase by some few KBs, but not completely. Remarking cache.readQuery() removes the increase entirely!

Potential alternatives to local storage? https://spectrum.chat/apollo/apollo-client/large-datasets-in-apollo-cache-inmemory-and-persist~e6e98cd4-a442-497c-9efb-5e8df016b97b

Cache appears to be expanded due to the caching of the actual query/mutation execution; "application > storage > local storage > apollo-cache-persist", and inside of the that "ROOT_QUERY" and "ROOT_MUTATION" keys, there are mutations that are being cached per request addTracker()...|updateTracker(...); each key has its name set to stringified JSON of the entire object that is being updated...

Either need to find a way to delete those, or specify a key (so that only one key is used per updateTracker() mutation...

I posted a question, and a solution that I came up with here:

          Object.keys(cache.data.data.ROOT_MUTATION).forEach(key => {
            // console.log("KEY", key);
            if (
              key.includes("updateTracker") &&
              key.includes(task.userTaskInfo.id)
            ) {
              delete cache.data.data.ROOT_MUTATION[key];
            }
          });
          Object.keys(cache.data.data.ROOT_MUTATION).forEach(key => {
            // console.log("KEY", key);
            if (
              key.includes("updateTracker") &&
              key.includes(task.userTaskInfo.id)
            ) {
              delete cache.data.data.ROOT_MUTATION[key];
            }
          });
