Indexing and relaying data to hot storage

A method is disclosed. The method comprises receiving, from one or more search nodes of a distributed system, one or more requests for log data, the one or more search nodes being associated with one or more hot storage systems; identifying, from an index catalog, an indexed portion of the log data stored in a cold storage system of one or more cold storage systems based on at least part of the particular request, the index catalog containing pointers to indexed portions of the log data in the one or more cold storage systems, the indexing being performed by one or more indexing nodes independently from the receiving by the one or more search nodes; and sending the indexed portion to the one or more search nodes for storage in the associated one or more hot storage systems, wherein the method is performed using one or more processors.
