System and method for investigating large amounts of data
First Claim
1. A computer-implemented method comprising:
- receiving a search parameter;
deriving a search criterion from the search parameter;
using the search criterion to obtain one or more first values from a first-key value family of a key-value data repository, the first key-value family mapping keys to data block identifiers;
using the one or more first values to obtain one or more compressed values from a second key-value family of the key-value data repository, the second key-value family mapping data block identifiers to data blocks;
uncompressing the one or more compressed values to produce one or more uncompressed values;
using the search criterion to identify one or more portions of the one or more uncompressed values; and
returning the one or more portions of the one or more uncompressed values as search results, the one or more portions comprising a byte sequential portion of the one or more uncompressed values.

Abstract
A data analysis system is proposed for providing fine-grained low latency access to high volume input data from possibly multiple heterogeneous input data sources. The input data is parsed, optionally transformed, indexed, and stored in a horizontally-scalable key-value data repository where it may be accessed using low latency searches. The input data may be compressed into blocks before being stored to minimize storage requirements. The results of searches present input data in its original form. The input data may include access logs, call data records (CDRs), e-mail messages, etc. The system allows a data analyst to efficiently identify information of interest in a very large dynamic data set up to multiple petabytes in size. Once information of interest has been identified, that subset of the large data set can be imported into a dedicated or specialized data analysis system for an additional in-depth investigation and contextual analysis.

9. A computer system comprising:
-
a key-value data repository comprising a first key-value family mapping keys to data block identifiers and a second key-value family mapping data block identifiers to data blocks; one or more processors configured to; receive a search parameter; derive a search criterion from the search parameter by at least one of transforming, converting, encoding, and canonicalizing the search parameter to produce the search criterion; use the search criterion to obtain one or more first values from the first-key value family; use the one or more first values to obtain one or more compressed values from the second key-value family; uncompress the one or more compressed values to produce one or more uncompressed values; use the search criterion to identify one or more portions of the one or more uncompressed values; return the one or more portions of the one or more uncompressed values as search results, the one or more portions comprising a byte sequential portion of the one or more uncompressed values. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
