GridDB utilizes multicast communication to form its cluster, so it's essential to configure the network for this purpose. Start by verifying the host name and IP address; you can do this by running the command “hostname -i” to check the host's IP address configuration. If the reported IP address matches the specified value below, you can proceed directly to the next section without any further network adjustments. GridDB is a database designed to manage a collection of data entries, each consisting of a key paired with several values. In addition to functioning as an in-memory database that organizes all data within the memory, it also supports a hybrid architecture that combines both memory and disk storage, which can include solid-state drives (SSDs). This flexibility allows for efficient data management and retrieval, catering to various application needs.
