| Iirc, Spanner is eventually consistent.

| When you get down to it, between cache coherency across CPUs

| And if you want to operate over a distributed network, which

| CAP and will need eventual consistency mechanisms.

| What is the use case for this ?

| How does OrbitDB compare to GUN?
| olah_1 wrote:
| Gun is a graph database. I don't think Orbit uses a graph
| system, but instead uses feeds or KV stores. So that's a
| another difference. But Gun can use IPFS as a storage adapter
| if you wanted.
| lildata wrote:
| One of the main difference is it is based on IPFS
| continuations wrote:
| What does GUN use instead of IPFS? What are the pros and cons
| of the 2 approaches?
| ekseda wrote:
| Another one is that the source code of OrbitDB is not

| Can you elaborate? Source code to GUN is right here:

| What I'd like to know is do they support authorization?
