Handling Large Amounts of Data with Parquet – Part 1

Know about the internal working of parquets and how does parquet achieve world class performance in terms of reads and writes

Exactly Once Semantics with Non-Idempotent Requests

Using PREPARE and COMMIT operations to make sure we achieve exactly once write or updates for non idempotent requests.

Building Replicated Distributed Systems with Kafka

In this blog, we are going to understand how can we easily build fault tolerant stateful services with kafka. Kafka provides us with concept of partitions which can be used for syncing writes among different replicas making sure that primary and replicas are in almost same state.

Understanding Spectre and Meltdown Vulnerability – Part 3

In this blog post, we are going to talk about spectre vulnerability and how does this vulnerability affect current systems all around the globe. As already discussed in previous blog posts, the processor uses speculative execution along with branch predictor to speculatively execute instructions for better utilization of CPU cycles.

Understanding Spectre and Meltdown Vulnerability – Part 2

One of the core security features of the modern operating system is to provide isolation between the different processes running on a system and make sure that one process should not be able to see the data used by another process.

Understanding Spectre and MeltDown Vulnerabilities – Part 1

In this blog series, we will go through one of the biggest security vulnerabilities of recent times i.e. Spectre and Meltdown. This article is mostly centered around understanding the concepts which will be necessary for then understanding the internals of these two vulnerabilities.

Exploring Code Generation with Janino

In this blog post, we are going to talk about potential advantages of using custom execution plan of a query rather than using the traditional iterator model in which execution is composed of many operators.

JIT Optimizations – Method Inlining

In this blog post, we are going to understand the impact of functions calls in an application and what JIT does to reduce its impact.

JIT Optimizations – Method Compilations

JIT ( Just in Time ) is certainly one of the most interesting features of JVM. This feature makes sure that we are able to run our code with machine level optimizations.

Java Unsafe APIs

Java Unsafe APIs provides various low-level APIs which could be used by programmers but we should be very careful when to use these APIs. These APIs provide a way to access off heap memory in java.
