Commands not listed above are not implemented.
NOTES:
[1] COMMAND is implemented only with no subcommands.
[2] HSCAN, SSCAN, ZSCAN. Native Redis supports a range of values of +/- the capacity of unsigned 64-bit integers (+/- 1.8446744e+19) for the CURSOR, but 64-bit signed integers for COUNT.
VMware GemFire for Redis matches native Redis’s behavior for COUNT, but only supports values of +/- the capacity of a signed 64-bit integer (+/- 9223372036854775807) for CURSOR.
[3] INFO is implemented for the sections and fields listed below:
| INFO section | Field(s) |
|---|---|
| clients | connected_clients blocked_clients (always returns 0) |
| cluster | cluster_enabled (always returns 1) |
| keyspace | db0:keys expires (always returns 0) avg_ttl (always returns 0) |
| memory | maxmemory used_memory mem_fragmentation_ratio |
| persistence | loading (always returns 0) rdb_changes_since_last_save (always returns 0) rdb_last_save_time (always returns 0) |
| replication | role (always returns “master”) connected_slaves (always returns 0) |
| server | redis_version redis_mode (always returns “cluster” because VMware GemFire for Redis always runs in cluster mode.) tcp_port uptime_in_seconds uptime_in_days |
| stats | total_commands_processed instantaneous_ops_per_sec total_net_input_bytes instantaneous_input_kbps total_connections_received keyspace_hits keyspace_misses evicted_keys (always returns 0) rejected_connections (always returns 0) pubsub_channels pubsub_patterns |
