Redis batch operation:

GridsTemplate.executePipelined ((RedisCallback) connection-> {gridsMap.forEach ((mmsi, grids)-> {if (! CollectionUtils.isEmpty (grids.getGridList () {connection.set (keyCreator.getKey (mmsi). GetBytes (), grids.toByteArray (), expiration, SetOption.UPSERT);}); return null;}); List result = gridsTemplate.executePipelined ((RedisCallback) connection-> {keys.forEach (key-> connection.get (key.getBytes (StandardCharsets.UTF_8) Return null;}); if (CollectionUtils.isEmpty (result)) {return Collections.emptyMap ();}
