Summary: SQL: Investigate parser generators Key: IGNITE-6276 URL: https://issues.apache.org/jira/browse/IGNITE-6276 Project: Ignite Issue Type: Improvement Components: sql Reporter: Sergey Kalashnikov Assignee: Sergey Kalashnikov Now ignite relies on H2 for SQL processing. It has been discussed many times on dev list that we must start introducing our own SQL core in small incremental steps. Let's start with analyzing the options for implementing the parser part. We may begin with http://www.antlr.org/ and create a simple separate project that would generate the parser for some simple DDL commands like DROP INDEX. This will give us a hint on the complexity and limitations of the approach. 1) Set up Maven/ANTLR. 2) Prepare lexer/parser. 3) Generate. 4) Write a test. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
