Abstract: Representative embodiments disclose mechanisms to map natural language input to an application programming interface (API) call. The natural language input is first mapped to an API frame, which is a representation of the API call without any API call formatting. The mapping from natural language input to API frame is performed using a trained sequence to sequence neural model. The sequence to sequence neural model is decomposed into small prediction units called modules. Each module is highly specialized at predicting a pre-defined kind of sequence output. The output of the modules can be displayed in an interactive user interface that allows the user to add, remove, and/or modify the output of the individual modules. The user input can be used as further training data. The API frame is mapped to an API call using a deterministic mapping.

Abstract: In a computing system, data is ingested into a primary row of shards in a stamp data structure. The stamp data structure includes a primary row of data shards and a set of replica rows of data shards so the data shards are arranged in rows and columns in the stamp structure. The ingested data is replicated from the primary row into the replica rows of data shards. Each of the data shards, in each row, is evaluated to identify a particular data shard in each column of shards to generate a logical row of data shards. Queries against the data shards are serviced from the logical row of data shards. The system dynamically controls expansion and contraction of the number of data shards in a row and of the number of replica rows.
