#Concept of Particles

Apache Storm works with tuples every one of which is a data item to be processed. The Particles (that is how we name our primitives) represent a special type of tuple. The features of Particle are:

• Every Particle has a timestamp;
• Every Particle is strongly typed. The Particles are matched to Apache Storm tuples automatically, therefore, there is no any break of compatibility with the basic Storm functionality.

##Data Particles raw data streams

##Meta Particles broadcast of particles of this type

###Grouper for MetaParticles

##Sync buffer

• apply ordering -use time window (now const) -duplicate Metaparticles filter if too late: rejected
