Scan
Remarks:
The Keys() call will select either the KEYS or SCAN command based on the version of the Redis server. Where possible it will prefer the usage of SCAN which returns an IEnumerable<RedisKey> and does not block. KEYS on the other hand will block when scanning the key space.
Basic scanning of all keys on server
// Connect to a target server using your ConnectionMultiplexer instance
IServer server = conn.GetServer("localhost", 6379);
// Write out each key in the server
foreach(var key in server.Keys()) {
Console.WriteLine(key);
}
Iterating using a cursor
// Connect to a target server using your ConnectionMultiplexer instance
IServer server = conn.GetServer("localhost", 6379);
var seq = server.Keys();
IScanningCursor scanningCursor = (IScanningCursor)seq;
// Use the cursor in some way...
Syntax:
public IEnumerable<RedisKey> Keys(int database = 0, RedisValue pattern = default(RedisValue), int pageSize = CursorUtils.DefaultPageSize, long cursor = CursorUtils.Origin, int pageOffset = 0, CommandFlags flags = CommandFlags.None)
Parameters:
| Parameter | Details |
|---|---|
| database | Redis database index to connect to |
| pattern | Unsure |
| pageSize | Number of items to return per page |
| cursor | Unsure |
| pageOffset | Number of pages to offset the results by |
| flags | Unsure |
