The solution I am after requires a data engineering development which should be able to query a postgreSQL database of 20 million records (2 crores). In the ideal scenario, the query should return 100,000 records under 5 seconds. I am looking for someone who is experienced in Apache Spark and able to show a proof of concept before developing a full system.

Hi, I'm a DB expert from Bulgaria(EU) with strong experience in wide variety of RDBMS: MySQL, PostgreSQL, MS SQL Server, Oracle, Teradata and a few others.. I have a solid knowledge in writing and tuning complex SQL queries, functions, stored procedures, etc... Besides that, I'm well familiar with the internals of the mentioned RDBMS, so I feel comfortable performance tuning and optimizing the database engines and structures (tables, indexes, statistics). Best Regards, Veselin Z.

I have been experienced in PostgreSQL for about 13 years. I have worked at big PostgreSQL projects like Turkish eGovernment and CableTV operator in Turkey. But I don’t know Spark. Regards,
