Example Embodiment
[0036] The present invention will be further explained below in conjunction with specific embodiments.
[0037] Reference Figure 1-2 , A solr-based Hbase second-level query solution proposed by the present invention includes the following steps:
[0038] Step 1. Insert the original data into the Hbase columnar database, keeping the original Hbase method, without any other changes;
[0039] Step 2. Invoke MapReduce regularly to incrementally update the index in Solr, first obtain the original data inserted into the Hbase columnar database and store the original data in Solr's unique document format in Solr's server. After the document is created, Solr will automatically perform the document Analysis, which involves segmenting the content of the document according to a specific word segmentation technology. After the word segmentation is completed, Solr uses the segmented word as the key and the document as the value for inverted index;
[0040] Step 3. When querying, visit the Solr s...
