A method and apparatus for automatic schema detection and migration is disclosed. In embodiments, a file including NoSQL data is received and one or more data types are detected in a hierarchical data table description. Within a record of the NoSQL data, which may be stored in a JSON format, a field name and its data type, are stored in a schema describing the data table. As additional records are parsed, the schema is updated to include additional field names and data types, and may include designations such as repeated and optional, for some fields. In embodiments, the schema is a serialized data format, such as Google Protocol Buffers (Protobuf).

Automatic flexible schema detection and migration

A data storage device that, in a first mode, emulates a Wi-Fi adapter to facilitate communication with the host device. When the data storage device is connected to the host device, a processor of the data storage device emulates a Wi-Fi adapter to the connected host device. This includes emulating a Wi-Fi network. Responsive to a request to join the Wi-Fi network, a further notification is sent to trigger a captive portal displayed at the host device. The captive portal facilitates additional communication between the data storage device and the host device. The additional communication can be related to one or more of authentication, access control, firmware updates, and configuration of the data storage device. The data storage device also includes storage medium that, in a second mode, is accessible by the host device.

Communication with a data storage device using an emulated Wi-Fi captive portal

A method and apparatus for carrying out a database select, or query, on a data storage device, upon data stored on that device. Data is received from a host and compressed on the data storage device using a compression code developed on the data storage device for the data. When the host issues a database select request on the compressed data, the compression code is distributed to processing cores of the data storage device and compiled, including the select request, into machine code. The machine code is used to decompress the compressed data while filtering the data with the select request. The filtering result is returned to the host.

Query compiler for record filtering

A method and apparatus for a database management architecture on an SSD. A list of tables is stored in the SSD, and records of a table are stored across multiple FIMs of the SSD such that a group of records may be read in parallel by concurrently reading from multiple FIMs. The records of the table are stored on jumboblocks, organized in an unordered fashion as a linked list. New records are added to the end of the linked list. Records having gaps resulting from data modification or bad portions of an NVM die are re-organized via garbage collection when the gap memory size reaches about 20% of table memory size.

Data storage device database management architecture

A method comprises receiving a set of content items comprising a first content item from one or more media devices via a network, transmitting the first content item to a host device for performance of enhancement tasks related to the first content item, receiving a first enhanced content item comprising the first content item and added metadata from the host device, and storing the first content item and the added metadata.

Assisted multimedia content enhancement

Disclosed herein are mobile devices that are configured to send data to a memory station and to be charged by that same memory station. The mobile device receives a trigger signal from the memory station responsive to the beginning of a charge cycle, the trigger signal indicating to the mobile device to initiate the backup process. The disclosed systems and methods include starting a backup application on the mobile device responsive to the trigger signal. The trigger signal is generated and transmitted wirelessly by the memory station responsive to the memory station detecting the beginning of a charging cycle. In this way, the mobile device can automatically execute a backup program or application without user intervention.

Automatic data backup and charging of mobile devices

A round robin system with interleaved weighted and priority arbiters to serve on-demand bandwidth of a storage system are provided. In one embodiment, a host assigns a priority and weight to each of a plurality of memory commands. The memory commands are sent to the storage system in a priority round-robin manner, in which memory commands assigned to a relatively-higher priority level are sent to the storage system before memory commands assigned to a relatively-lower priority level. Further, memory commands assigned to a given priority level are sent to the storage system in a weighted round-robin manner in accordance with their assigned weight. Other embodiments are provided.

Disclosed herein are memory stations that are configured to charge a mobile device, to receive data for storage from the mobile device, and to transmit a trigger signal to the mobile device responsive to the beginning of a charge cycle to initiate the backup process. The disclosed systems and methods include starting a backup application on a mobile device responsive to a trigger signal. The trigger signal is generated and transmitted wirelessly by a memory station responsive to the memory station detecting the beginning of a charging cycle. In this way, the mobile device can automatically execute a backup program or application without user intervention. The disclosed memory stations and related methods beneficially enable seamless data backup while charging a mobile device. This can be accomplished with no user intervention.
