Systems, methods and computer readable medium for storing data elements transmitted via data streams received from distributed devices connected via a network. The received data elements may be stored in block stores on the distributed devices. The stored data elements may be allocated to data blocks of a block store that have assigned block identifiers and further allocated to events of the data blocks. Stream schema of the received plurality of data streams may have the same stream schema, and indices may be generated indices based on the order of the event allocated data elements. Stream schema of the received data streams may comprise a list of token names. Token names may be assigned to the event allocated data elements. Indices may be generated for the event allocated data elements based on the stream schema.
